4Patriots Power Sidekick (299Wh): The specs on this small unit are ok – 87% usable capacity is about the norm and it charges at about one watt-hour per minute. That’s a bit slow, but not unheard-of for these small units. It does come with a small, 40-watt solar panel, but I think it is still overpriced at $500.

4Patriots Power Generator 2000X (1612.8Wh): While I do think this is a better engineered product than the smaller Sidekick offering from 4Patriots, I still feel like their product lines are overpriced. Again, they do come with small solar panels, but that is hardly worth double the sticker price in many instances. Usable capacity is still in line at 87% but this size unit only charging at 7Wh/min is a bit underpowered in my opinion.

Ampace Andes 600 Pro (584Wh): This is an OK unit. It sits right around the industry standard for usable capacity. We did find that the charging moved much slower than the marketing materials claim: 90 minutes to 80% charge vs. the advertised 60 minutes.

Apace Andes 1500 (1462Wh): There are a couple of notable improvements between the smaller Pro unit I previously tested and this larger 1500Wh unit. For one – weight. The spec capacity is almost three times larger, and normally capacity and weight are proportional, but despite the larger capacity, the 1500 weighs only a little over double the smaller unit. This thing charges quickly too. It doesn’t quite hold up to the company’s 55-minute charge time claim, but one hour and sixteen minutes isn’t bad!

Bailibatt 300W (257Wh): Another small, affordable unit. The Bailibatt comes in at 84% usable capacity, which is good. It takes 11 hours to charge, which is…. not as good. If you have specific limited charging needs and plenty of time to recharge, the price tag makes it worth considering.

BigBlue Cellpowa 500 (537.6Wh): This is a better-than-average performing unit at better-than-average pricing, but there’s nothing outstanding about it. 

Dabbsson DBS2300 (2,300Wh): I love that it’s a modular format, expandable up to 8.33kWh. The 87% usable capacity is good and charges relatively quickly. It charges at over 18 watt-hours per minute, for a total of 122 minutes to charge the entire 2,300Wh.

Dakota Lithium PS 2400 (2,060.8Wh) Update: Out of stock: The Dakota Lithium PS2400 is the fastest-charging portable power station on our list. Now, looking at our test data, that doesn’t mean that it took less time to charge than any other unit, but, in using our residential AC charging method, it instead indicates the unit that charges the most watt-hours per minute. This method allows the large-capacity units to compete in this category with much smaller units that naturally charge much faster. It showed a respectable 90.72% in usable capacity while also giving us our fastest charge metric to date. We showed a charge rate of 26.76 watt-hours per minute, just edging out the Oupes Mega 3 by about 0.3 Wh/m.  Also notable is the unit’s 10ms switchover time. Charging from 0% to 100% in 77 minutes, the PS2400 sees 26.76 watts-per-minute charging from a standard 120-volt, 20-amp residential outlet. A close second was the Oupes Mega 3 at 26.48 watts per minute, followed by the VTOMAN Flashspeed in a more distant third at 24.9 watts per minute. Different units make up the bulk of the next-best contenders, from companies like Oupes, VTOMAN, UGreen and Goal Zero. If charging to recover your total capacity is a major concern for you, these are the units to look at. In addition, they all offer simultaneous charging from other inputs like solar or other DC inputs if you need to up your recharge game.

DaranEner NEO2000 (2,073.6Wh): This unit didn’t win any categories, but it did perform in the top tier for our charge tests and came in about average for our usable battery capacity tests. This sturdy unit has plenty of features and one of the lowest prices per watt-hour.

Deeno GT S1500 (1,036Wh): We previously tested the Deeno GT X1500, and the S1500 is a big step up. It has the same capacity and same pricing, but with nearly 20% more usable capacity than the previous model and it charges nearly five times faster.

Deeno X1500 (1,036Wh): The X1500 did not fare well in our tests. It came through with one of the lowest usable capacity scores we’ve collected so far at 69.88%, meaning you see about 724Wh out of the stated 1,036Wh. For the price, there are better options. 

DJI Power 1000 (1,024Wh): I want to note first off that I do not have a drone that’s compatible with the SDC super-fast charge function for select DJI drones. I think that’s likely to be one of the best selling points for this particular unit. I’m also happy that there are two 140-watt USB C ports. Outside of those features, there isn’t much else to talk about. It does charge fast but it came in low on our usable capacity test.

Duracell Power 500 (515Wh): This is the first Duracell unit I’ve tested, but not the first battery brand to put out a portable power station (see Energizer at the top of this list). So far, the results are similar. Test results come back with under-average performance and questionable prices. 

Duracell M250 (219Wh): Overall, this smaller unit is proportionally comparable to the larger Power 500 Duracell model. The M250 came in at 75% usable capacity, just a couple of points higher than the Power 500. You’re getting approximately half the capacity for half the price. Charging is also in line, taking around the same time (4+ hours) to charge half the capacity (at half the input power). I like the cylindrical shape — I’m guessing Duracell wants it to look like that familiar battery profile — and that the lid opens up to allow for power cable storage within the unit.

EBL MP1000 (999Wh): This is not a bad little unit. Doesn’t charge too quickly, but overall usable battery capacity is good. It has a wireless charge pad and lots of options for inputs and outputs. It isn’t something I’d run out to buy for myself, but if you can catch it on sale, it could be a low-cost way into a smaller power station.

Encalife UAF550 (595Wh): Of the three Encalife chargers, this has the largest usable capacity percentage at 87% but the slowest charging at 1.98-watt hours per minute. 

Encalife UAF1100 (992Wh): Industry standard usable capacity here at about 84%, but a bigger drop in the charge capabilities at 3.35-watt hours per minute from its larger sibling.

Encalife YUE2000 (2,048Wh): A bit of variation in our model hierarchy groupings with Encalife. As you might expect, charging capabilities do increase with larger units. The YUE2000 being the largest of the three charges relatively quickly, at about 11.13 watt-hours per minute. In this series, the usable capacities trend in the other direction, with this unit showing 73% usable capacity.

Enernova ETA 288 (288Wh): This is another example of a hierarchy of models where the smaller units underperform, but larger models improve. This unit took about 3 hours and 40 minutes to charge, but it reached about 81% usable capacity. 

Enernova ETA Pro (1,050Wh): Moving up a notch, this one has 83% usable capacity and charges 1kW in about 1 hour and 30 minutes. It’s a better showing and about 10 cents cheaper per watt-hour than its smaller sibling. 

Enernova ETA Ultra (2,150Wh): This is the best of the three, sporting 2160Wh, 87% usable capacity and it charges in under 2 hours. 

Energizer PPS700 (626Wh) (Update: Currently Unavailable): OK performance and features overall, but one of the lowest-tested capacities, making the usable capacity closer to 477Wh.

Etaker M2000 (2008Wh): While the M2000 didn’t win any of our categories, I do like the platform. More manufacturers are offering increased capabilities like ones you’ll see here: semi-solid state battery engineering, modular platform to increase capacity, ability to expand to 240VAC, direct EV charging and a few more use cases that are more niche. It’s a reasonable grab, especially if you’re looking for something more sturdy like cold weather charging — all with a usable capacity percentage of 91 — above average for the units we normally test.

Fanttik Evo 300 (299Wh): This is a solid pick in the small power station category, and this unit has my favorite display: It’s extra large and easy to read. We did see average performances on our charging and capacity tests.

Generac GB1000 (1,086Wh): Generac has been a household name in the power landscape (especially generators) for dozens of years in the US. It isn’t that surprising to see it here in the portable battery space. I wasn’t blown away by this unit. It tested quite average (if not a smidge below on charge speed) but overall, still does what you need: to transport power.

Geneverse HomePower One (1,002Wh): This unit was the second slowest overall to charge, but did well on its usable capacity rating at 91%. Its display is small but offers all the standard input and output features you’d want.

Geneverse HomePower One Pro (1,210Wh): This is the grownup version of the Geneverse HomePower One. The feature specs are about the same, but at $500 more, you’re only getting about 200 extra watt-hours. In addition, the standard One model comes in at 91% usable capacity versus the Pro model’s 73%. That gives you 912.6 usable watt-hours with the standard and only 886.7Wh on the Pro. The Pro charged in almost a quarter of the time it took the standard version. 

Goal Zero Yeti 200X (187Wh):: The Goal Zero products are solidly made, but we got the lowest score in our “usable capacity” tests from this unit. It’s about 65% compared to the industry-accepted norm of 85%. There are better products in the small portable power station category. 

Goal Zero Yeti 700 (677Wh): Overall this unit tested OK; nothing outstanding. One of the more interesting aspects of the design is the use of plastic protective ‘flaps’ covering the in/output ports. The use case here seems to be for a more rugged durability for camping or otherwise roughing it where you might have an increased exposure to mud, dirt, dust or water. Outside of those environments, the flaps can be bothersome.

Goal Zero Yeti Pro 4000 (3,993.6Wh): Runner-up for our best extra-large power station title, the Yeti Pro 4000 is a tank (which, by the way, is the name of the expansion battery: “Tank Pro 4000”). You get tons of input and output options, and it is expandable to 20kW capacity. We were able to charge this via standard AC outlet in 2 hours and 49 minutes, giving us our third-fastest charging rate so far at 23.63 Wh/min charged. It also offers 3,000-watt solar input. If you’re looking into home backup, also check out the Haven10 transfer switch accessory to bring your home online.

GoSun PowerBank 1100 (1,100Wh): I wanted to like this unit more, partially because of GoSun’s extended offerings of solar-friendly devices. As far as capacity goes, this runs in the middle of the pack, but man is it slow to charge. It took nearly 12 hours — over six times as long as our largest power station (Jackery Explorer 2000 Pro) — which offers nearly twice the capacity. At $1,199, I’d like to see a faster charging option and more outputs or at least wireless charging.

Lion Energy Safari (1,612Wh): I tested two units, the first I’ve had my hands on, from Lion Energy. Two immediate observations on the superficial side: First, I like the physical packaging of these units. It reminds me of Oupes, which I also like. Second, these things sound like the names of energy drinks. Otherwise, I wasn’t impressed. This larger unit also had a bad connection to its display screen. In general, the color screen looks better than most other options. In my case, I had several lines plaguing each view.

Lion Energy Summit (665Wh): The TL;DR is above, with the larger unit, but for additional context, units tested about average in terms of usable capacity. My main performance complaint is the charge speed. Both units are a bit low for their capacity category. I would be happier if the Summit charged at the Safari rate, and the Safari was retooled for nearly double its current speed.

Litheli PowerHUB B600 (562Wh): This one can be slow to charge, but otherwise, there’s a lot to like here. It has good usable capacity at a decent price, since it’s currently marked at about 40% off. Litheli is also offering a battery platform (U-Battery) with this unit. Two smaller batteries plug into the main unit that you can then use with a variety of other tools. Check out our upcoming coverage on handheld vacuums to see Litheli’s performance there. 

Litheli PowerHUB Eclair1000 (1,069Wh): Another unit from Litheli offering the U-Battery platform, but it’s closer to double the capacity of the last unit we tested. The capacity score was low, but the charge speed has vastly improved from the B600. Worth a look if you’re interested in the U-Battery platform.

Mango Power E (3,530Wh): I mentioned this unit earlier as the runner-up in the fastest charging category. This thing is loaded with features, even allowing you to provide 240-volt service by linking a second unit. There are also battery expansions for the Mango Power E. The one downside is the price tag, as this unit also comes through as the most expensive portable power station with a list price of $4,250. 

Milwaukee M18 Carry-On Power Supply: It isn’t a great portable power station. You’re probably considering buying it because you’re already on the platform. If that’s the case, I say go for it. It will work with all batteries on the M18 platform, so you have some control over how much juice you want to carry around. This will put a fair amount of convenience into situations for people who are Milwaukee tool users and find themselves in energy-shy situations.

Monster Power Grid 300 (296Wh): The Power Grid 300 can be slow to charge but did test at over 90% usable capacity. It has all the bells and whistles you’d expect at this level at a price that’s a tad high. 

Oscal PowerMax 700 (666Wh): Another unit that didn’t perform particularly well in our tests, but does boast a ton of features, including a “non-stop continuous power supply mode.”  

Oukitel BP2000 (2,048Wh): This is the first unit we’ve tested from Oukitel (along with its expansion battery — we will be publishing more on expansion batteries soon) and we were pleasantly surprised. To begin, the BP2000 scored an impressive 90% on usable battery capacity and also scored well in our charge tests, taking less than 2 hours to charge all 2048Wh of capacity. Oukitel is also leaning into the modular and expandable approach, allowing you to add up to seven additional units for a total of just over 16kWh of power. The BP2000 also boasts sub 10ms switchover time as its UPS feature.

Pecron E1500 (1,536Wh): I will say that I’m a bit torn with this unit. I tested the E2000LFP model first and was impressed with the results. The E1500LFP did not fare as well. Specifically, the usable capacity came in especially low at 68% compared to the E2000 at 94%. Other than that, the charging is beefier, charging at about twice the rate as the other unit. And you still get perks like wireless charging and expandability from 1536Wh up to 7680Wh.

Pecron E2000LFP (1,920Wh): I discussed this unit briefly earlier as the runner-up to the Delta Mini in the “best portable power station for camping” race. It has more options than the Mini and is suitably priced. I’m also a fan of any of the companies that adopt the modular approach with the capability to expand capacity with external batteries, like Pecron has done. You can also pick up a rolling caddy for the unit if you’re on the go.

Phyleko ENF1000S (1,024Wh) (Update: Currently Unavailable): I’ve seen this body style before in the GoSun 1100; it feels super sturdy and I do like the larger colorful display. Otherwise, this unit landed just under average in our tests. 

Power Cache 300 (293.76Wh): We tested a trio of power stations from Power Cache. The 300 model did well as far as usable capacity goes (91%) but took over 7 hours to charge. Another upside is that it’s affordable, with a $200 retail tag.

Power Cache 600 (642.6Wh): Costing $250 more than its smaller sibling, this middle child showed the least impressive performance of all three models, coming in at only 72% usable capacity and taking over 8 hours to charge to 100%. If price is your main concern, it’s an affordable option.

Power Cache 1000 (1,075Wh): The largest of the three units, this one performed moderately, coming in at 82% usable capacity and taking about the same amount of time to charge as the small 300 model, which is just over 7 hours. That does mean it charges over four times faster than the small unit, but 7 hours is still 7 hours. Selling at $470.

Renogy Phoenix 200 (189Wh) (Update: Currently Unavailable): Slower to charge, but it has 96% usable battery capacity paired with the lowest price of any unit we’ve tested. This a great option for smaller use cases or for people generally interested in checking out portable power stations at a reasonable price. 

Renogy 1000 (998.4Wh) (Update: Currently Unavailable): This is another decent performer. It charges fast enough for its relative capacity category, but only offered us about 80% usable capacity. Normally, I wouldn’t be too bothered, but the smaller Renogy unit we tested clocked in at 96% usable capacity, so I was hoping for more. 

Rockpals 300W (Update: Currently Unavailable): This unit also came in under the line in usable capacity. Given the industry standard of 85%, Rockpals’ 78% is lacking. In terms of charge speed, this unit is one of the faster small portable power stations. It has decent features and kind of looks like a handheld radio. 

Rocksolar Nomad RS650 (444Wh): Until the company updates this unit, there are likely better options for almost anything you’re looking to do. It has a high price, low usable capacity, slow charge time and is low on features and options, but it does work. 

Runhood Rallye 600 (648Wh): There are a couple of these types of units on the market now, and I’ve been waiting for their arrival. This Runhood unit is the first modular-style portable power station I’ve been able to get my hands on, and I love what it means for the industry. Performance-wise, this model was about average, but it could offer you more flexibility and convenience than many other units. The batteries are swappable, so you can pick up extras, in addition to standalone AC and USB modules that can use those extra batteries without being plugged into the main power station unit. This could be a game-changer for trips where every member of the family is off in a different area draining some electronic device. I look forward to adding a “best modular power station” category soon.

Runhood Rallye 1200 (648Wh) (Update: Currently Unavailable): The capacity is the same for this unit as it is for its younger sibling, the 600 (listed above). The 600 and 1200 designations refer to the constant power output in watts, with each unit’s peak power doubling that constant power number. You do get an extra AC outlet but the increase in power output is the main difference. Likely worth it if you’re into the modular design, but need more power than the 600 has to offer.

Segway Cube 1000 (1024Wh): I am always excited to check out new entries into the portable power station category, especially from companies that are already in similar spaces. The Segway Cubes are a solid first product, leaning into modularity and avoiding an attempt to match all the latest bells and whistles. The units show an average usable capacity percentage, the same for charge speed.

Segway Cube 2000 (2040Wh): The Segway Cubes are offered in retail capacities of either 1 or 2kW. The platform is expandable to 5kW. The interesting choice is Segway’s decision to offer both the 1kW and 2kW retail options, when both options are otherwise identical and identically expandable. It seems that either retail option contains an identical inverter and 1kW battery. The Cube 2000 offers an additional battery expansion that goes between the two previously mentioned units. At that point, you can add a total of four battery expansions to max out the platform at 5kW.

Togo Power Advance 346 (346Wh): This unit held the title for best small portable power station for about two years on this list; solid performance, great features and an attractive price tag. 

Ugreen Power Roam 600 (680Wh): This unit didn’t do great in our tests, but it has a reasonable price. It charges quickly, but that has more to do with the smaller capacity than an elevated charging capability. 

Ugreen PowerRoam 2400 (2,048Wh): I was happy to see that this model did better than the previous smaller model we tested. 83% on usable capacity and it charged in the same amount of time as the smaller unit, about 1.5 hours for each one, which means the 2400 was charging at about four times the rate. This one also has wheels and a telescoping handle for ease of movement.

VTOMAN Flashspeed 1000 (828Wh): This is the second VTOMAN Flashspeed I’ve tested and the smaller of the two. This smaller unit didn’t fare as well as its big brother in our tests. While it’s a capable machine, I struggle to find a scenario where the minimal cost difference between the two would keep me from buying the 1500 over the 1000.

VTOMAN Flashspeed 1500 (1,548Wh): This unit did about average on our usable capacity test, but, charging from 0 to 100% in 64 minutes, the FlashSpeed 1500 sees 24.19 watts-per-minute charging from a standard 120-volt, 20-amp residential outlet, which is one of the fastest charge rates we’ve seen here in the test labs. If charge speed and time are primary concerns for you, it’s almost impossible to do better than the Flashspeed 1500.

Yoshino B330 SST (241Wh): This is a cute little power station. It has a USB-C 100-watt port, a couple of AC outlets and is pretty light for what it offers. It comes in just above average for usable capacity but does have a slow charge rate. If you’re looking for a little power in a compact package, it’s worth considering.

Yoshino B4000SST (2,611Wh): This unit tested fairly well in our lab. 87% usable capacity, blazing-fast charge speeds and a decent feature set. It’s an option worth considering, if you can find it on sale. 

Zendure SuperBase Pro 2000 (2,096Wh) (Update: Out of stock): The first unit we tested with the Li-NMC battery composition. This unit also just missed the best large portable power station title. It has a weight-to-capacity ratio, likely thanks to the NMC composition, and boasts our highest solar charging capacity to date at 2,400 watts. Its telescoping handle and wheels make it easier to manage, but the form makes it better for navigating paved walkways than “off-road” terrain. 

70mai Hiker 400 (378Wh) (Update: Out of stock): This unit didn’t fare too well in our tests, coming in at about 75% usable capacity (versus the industry standard of 85%) and taking about 4 hours and 30 minutes to charge its 378Wh. 

70mai Tera 1000 (1043.9Wh): The larger of the two 70mai units tested better, hitting the industry standard for usable capacity and taking about 20 minutes less to charge nearly three times the capacity of the smaller model.
