How we test portable power stations

Currently, we look at two main performance metrics for portable power stations: charge time and discharge capacity. Every company that sells portable power stations provides the expected number of watt-hours its products are supposed to last. For the Jackery Explorer 240, that’s 240 watt-hours; for the Ecoflow River Max, it’s 576 watt-hours. Bluetti AC200P claims 2,000 watt-hours. 

That means if you run a device with a 1-watt output on the Jackery Explorer 240, it should last for about 240 hours. You’d get 576 hours from the Ecoflow model and an impressive 2,000 hours using the Bluetti generator. That would last you almost three months. For reference, a USB-C iPhone charger draws up to 18 watts, a 3-quart Instant Pot draws 700 watts and a standard microwave draws around 600 to 1,200 watts, depending on the model. But how accurate are those figures?

We use 110-watt&nbsp;LED lights to run a controlled load on each power station during our tests, which allows us to calculate the percentage of power that you can actually use.

” image-credit=”Ry Crist/CNET” image-alt-text=”img-4968.jpg” image-filename=”img-4968.jpg” image-date-created=”2024-01-29″ image-width=”4032″ image-height=”3024″ image-do-not-crop=”true” image-do-not-resize=”false” image-watermark=”true” lightbox=”false” edition=”us” class=”c-shortcodeImage u-clearfix c-shortcodeImage-large c-shortcodeImage-hasCaption”>

To run our capacity tests, we connect a number of 10,000-lumen LED work lights, rated at 110 watts, to each unit. (The number of work lights is based on the overall watt-hour rating of the unit under test, or UUT.) We record the outgoing voltage and wattage using external measurement instruments or the UUT’s own measurements if available. Once we have this data, we can leverage the calculations into a dizzying array of information about the UUT’s performance. The main piece of information we look at here is the observed capacity, based on our measurements, compared to the UUT’s stated capacity.

Here’s that mass of data in a nifty chart, where longer bars indicate power stations with greater percentages of battery capacity that you can put to use.

In every case, that percentage ends up at less than 100%. Most manufacturers say you should calculate expected usage at 85% of stated capacity. Two of our smaller units (green bars) both clocked 98% capacity — the Jackery Explorer 240 and the Togo 350. Generally speaking, the midsize units (blue bars) didn’t fare well. The large-sized units (yellow bars) did better, with the Bluetti AC200P scoring highest at almost 96%. As for our extra-large units (purple bars), the 3,600Wh EcoFlow Delta Pro fared the best, with a usable capacity rating just over 92%. Behind it, Oupes, Mango, Yoshino and Dabbsson each had extra-large power stations (at least 2,200Wh) that scored above that 85% benchmark for usable capacity.

A quick word on our math here. If you blindly accept both a unit’s stated capacity and our work light wattage rating of 110 watts, the numbers look very different. For example, we will take the GoSun PowerBank 1100 (to make the math easier) and attach four of the 110-watt lights. That load rating is now 440 watts and the GoSun’s capacity of 1,100 divided by 440 is 2.5. We would expect to see 2.5 hours of usage. The actual run time for this unit was 2 hours, 50 minutes — 113% capacity. Sounds great, Right? We’re missing some key factors. Without going into a long(er) explanation of how to more accurately measure power, the fact that this unit has an output of 110 volts AC (compared to 120VAC) and the actual output wattage to the four lights is 352 watts, our real expected run time is 3 hours, 8 minutes, which drops the capacity rating to 90%.

One other testing note for these numbers — the Oupes 600W data might be off. The unit turned off the lights at 9%. It would allow me to start the lights again but would turn them off again after some time. I repeated this process at least 20 times before the unit wouldn’t power the lights for more than a couple of seconds at a time.

How long does it take to charge each of these things from zero to 100%? Glad you asked!

BioLite BaseCharge 1500 (1,521Wh): Having tested both the 600 and 1500 models of the BioLite BaseCharge, I can tell you that this company is consistent in its product manufacturing. The BaseCharge is about 2.5 times the capacity of the 600. That 2.5 modifier carries across the board fairly accurately from price to capacity, charge times, everything. If you like the 600 but you wish you had two and a half of it, save yourself the effort and just buy the 1500.

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. 

Bluetti AC180 (1152Wh): This unit tested well enough, scoring 88% usable capacity and charging via AC outlet at 13.88 watt hours per minute, but one thing to clarify, unlike many of the other Bluetti units that use the same physical format, this unit does not support capacity expansion via external batteries. 

Bluetti AC2A (204.8Wh): A great option if you don’t need a ton of capacity but do need options beyond just USB connectivity. This unit is in the capacity ballpark of a very large power bank and priced similarly while currently on sale through the manufacturer for $179.

Bluetti AC200P (2,000Wh): This is one of Bluetti’s earlier large portable power stations and a previous winner for “best large portable power station.” It’s currently over $500 off on Bluetti’s site. It still offers plenty of power and options, but is likely nearing the end of its product cycle lifespan (hence the $500 discount). 

Bluetti EB3A (268Wh): If you’re interested in something small to work for your personal charging needs but those pocket-sized battery packs just don’t cut it, this could be your option. As a previous CNET “best value” winner, the EB3A has what you need to keep rocking for a couple of days. 

Bluetti EB55 (537Wh): We’ve liked almost every unit from Bluetti, and three of them took previous titles in this best list, but this unit was overshadowed by its siblings. Offerings that are just as good or better at better prices keep the EB55 out of the winner’s circle.

BougeRV Fort 1000 (1,120Wh): I’m a fan of BougeRV’s approach to camping and outdoor products in this space. It’s worth checking out, especially if you’re looking for more flexibility in areas like solar panels or DIY options. The Fort 1000 did well in our tests but didn’t stand out enough to capture any titles. 

Dabbsson DBS2300 (2300Wh): 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 2300Wh.

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 (1036Wh): 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 5x 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 1036Wh. For the price, there are better options. 

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

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.

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:: 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 Pro 4000 (3993.6Wh): 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 overall 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, and also offers 3,000W 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 6x as long as our largest power station (Jackery Explorer 2000 Pro) — which offers nearly twice the capacity. At $1,299, I’d like to see a faster charging option and maybe more outputs or at least wireless charging.

Jackery Explorer 240 (240Wh): We’ve been fans of all the Jackery units we’ve ever tested in the past, and that doesn’t change here. Just missing the best small power station title, this unit still boasts the second-best capacity rating of all the ones we tested. It was a little slow to charge but is offered at a great price.

Jackery Explorer 300 Plus (288Wh): Another nice entry into the platform, the 300 Plus offers a solid power option in small form. Not a ton of frills, but it does what you expect it to do. 

Jackery Explorer 700 Plus (680.96Wh): If you need more power output than the 300 Plus (300W/600W) then the 1,000W (2,000W surge) of the 700 Plus may be what you’re looking for. It will charge via AC in about 1 hour and 30 minutes, and it has one of Jackery’s higher usable capacity percentages at 88%. 

Jackery Explorer 1000 Pro (1,002Wh): The 1000 Pro falls into our large portable power station, which begins at 1,000Wh (this Jackery weighs in at 1,002Wh; the same as its big brother, the 2000 Pro). I like the 2000 more than the 1000 for a few reasons, so the 1000 never had a shot at taking the “large” category. That said, it still has good performance, nice features and amazing charge times.

Jackery Explorer 1500 Pro (1512Wh): With this Jackery you will get a dependable machine that performs well in our usable capacity tests at 90.4% and charges quickly: 0 to 100% in 2 hours, with AC-only charging. Toss in a couple of solar panels and you can drop that time down quite a bit. 

Jackery Explorer 2000 Pro (2,160Wh): This was a previous title-holder of the “fastest charging portable power station.” The Jackery units overall are great and dependable. If you’re looking for a model (really, an entire lineup) that will recharge fast with multiple, even combined options, Jackery is a no-brainer. 

Jackery Explorer 3000 Pro (3,024Wh): Another beast of a unit and a great offering from Jackery. If you’re already a Jackery fan but need more battery capacity, this is an easy win for you. Otherwise, recent improvements include wheels, telescoping handling and that round RV plug we’ve been waiting for.

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 30% 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.

Though pricey, the Mango Power E is our runner-up pick in the fastest-charging category, and capable of charging its impressive 3,530Wh capacity battery from zero to 100% in less than 3 hours.

Renogy Phoenix 200 (189Wh): Slower to charge, but with 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): 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: 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 they update 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 in flexibility and convenience than many other units. The batteries are swappable, so you can pick up extras, in addition to stand-alone 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): The capacity is the same for this unit as it is for its younger sibling, the 600 (listed above). The 600 and 1,200 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 that modular/swappable design, but need more power than the 600 has to offer.

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 (2048Wh): 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 an hour and a half for each one, which means the 2400 was charging at about 4x the rate. This one also has wheels and a telescoping handle for ease of movement.

Yoshino B4000SST (2611Wh): This unit tested fairly well in our lab. 87% usable capacity, blazing fast charge speeds and a decent feature set; an option worth considering if you can find it on sale.

The Zendure SuperBase Pro 2000 is another interesting option, and one of our top-tested large-sized power stations.
