This Portable Power Station is compact and lightweight, making it very easy to carry around. I took it camping over the weekend, and it worked great for charging my phone and drone batteries. The AC outlet had no trouble powering my laptop, and it charged much faster than I expected, so I didn’t have to wait long. The 88Wh capacity is more than enough for short camping trips and everyday emergency use. It runs almost silently, so keeping it next to my tent at night didn’t disturb my sleep at all. It’s also reassuring to have as a backup power source at home—during a power outage, it can keep my router and phone running, which makes it incredibly practical.

This portable generator is exactly what I needed for my camping trips. It’s small and lightweight, easy to carry around. All ports function well, I can charge my laptop, cell phones and camping lamp simultaneously. The AC outlet works steady for low-wattage gadgets, and the LED light is really useful after dark. It charges fast at home, and the optional solar panel makes it ideal for off-grid use. The build quality feels solid, no cheap plastic feel. Great backup unit for unexpected power cuts at home too. Very satisfied with my purchase!

This power station works great. I went camping with it couple time. Held a charge of its own for couple hours. It charges fast for multiple items at a time. Really great size for on the go. It is versatile with all its different ports and the design is simple and clean. Great buy and great price!!!

It's not bad for what it is, although the capacity feels more modest than the claimed 88 Wh, and the charge level indicator is all but useless. It tends to stay at 4 and 3 bars forever, and then suddenly drop off to empty without a linear progression through 2 and 1 bars. The AC output is definitely not a pure sine wave, and while it works OK for devices with their own switching power supply (such as an LED projector), a soldering iron I connected and that was well within the output limitations of the outlets overheated way beyond the set point, making me think that there's something wonky about the AV power provided. Still, for basic USB power, phones, lights, some low power AC devices, and the built-in super powerful flashlight, it's not a bad little device.

I got this in August 2024 and it is only now January 2025 and it doesn't seem to be working correctly. I just tried to use it to power my laptop while it itself is plugged in and it was fine for a little while but all of a sudden stopped doing anything and won't power the laptop any longer. I have the Marbero battery plugged in and I pressed the Power button and then pressed the Outlet button. Like I said, it was fine, the blue battery bars were full and the red plug picture lit up. Now the blue battery bars is only showing one, it's blinking, and when I try and turn on the Outlet button it blinks red quickly but doesn't do anything. I've checked the outlet this device is plugged into and it's working fine and other things that are plugged into the same outlet are working no problem. I originally gave this a great review and I thought it was great and very helpful but it hasn't even been a year and I've only used it I think two other times (aside from when I first got it to test it out) so I'm really annoyed by this. Below is my previous review. I work from home so that means that I need to have my modem/router and laptop plugged in and getting juice for the entire time I’m working. Thankfully, my shifts are only two hours at a time and neither my router nor laptop are all that power-hungry. But any time that I’m not able to work that’s time that I’m not getting paid for and that’s obviously a problem. My power has gone out more than once while I’ve been working so I’ve been looking for something like this for a while and it happened again recently so I decided enough was enough. I got this hoping that I can prevent losing any work time (and money.) I’ve looked at other, similar power stations, but they were either way too expensive, way too big/overkill for my needs, or both. This one was inexpensive and had a coupon and it seems to be able to do what I need. I especially like that it has regular outlets for things that have two or three prongs (like my modem/router). In addition to that it’s got multiple USB ports, a USB C port (for my laptop), and even has a port where you can plug in a car charger (it also includes the car charger adapter thing). In addition to that, there is a big flashlight that is nice and bright and has three brightness levels and an SOS mode. If you do use the flashlight keep in mind that aside from that eating up power from the device, the brightness that you have it set to will determine how long you’re able to use it. In other words, if you have it at the brightest level you won’t be able to use it as long as if you have it at the dimmest level. The same thing goes for what you’re charging with it. If you’re using it to charge a phone you will get more use out of it than if you’re using it to power a computer. Different devices use different amounts of power so it’s hard to say how much of a charge you will get from what you’re using it for. The entire device is quite small, smaller than I realized when purchasing it, and is also very light. I think it would be useful to have when road-tripping, camping, backpacking, etc. because of how tiny and portable it is. I also want to point out that you can get a compatible solar panel to use with this which can help charge it and recharging it via a wall outlet will bring you up to around 80% in about two hours. Now, there are others out there that will charge to around 80% in less time, but they’re also quite a bit more money. This one also has these safety features that I wanted to point out: Short-circuit Protection, Low-voltage Protection, Over-current Protection, Over-voltage Protection, Over-load Protection. So in simple terms, you don’t need to worry about it lol.

A great portable power source for smaller electrics, sufficient to drive a laptop, and it has a built-in LED lamp. I use it to be able to work remotely on the beach and in the woods when there's no other power supplies for my laptop, it works pretty good so far, it can last for a whole day if just to use my laptop alone. It's also pretty small and not too heavy at all, so quite portable and easy to carry to travel with, also when it works, it doesn't make as much noise as other similar products I have used before. It's definitely a great choice in terms of portal power sources.

I purchased this unit as a portable power supply so I could run my laptop and work from anywhere for an entire day. For that purpose, it’s okay. It does function as a portable battery, but there were several limitations that ultimately led me to return it. The biggest issue is the charging system. This unit uses a proprietary charger where a wall adapter plugs into a small round port on the battery. It’s not USB-C, and it’s not a standard connection that you could easily replace or even use with something like a solar panel. If that charger gets misplaced, the device effectively becomes unusable until you track down a replacement. In my experience, chargers are often the first thing to disappear with portable devices, so this design choice was a major drawback. The construction also feels somewhat flimsy for the price. It works, but it doesn’t give the impression of being particularly durable. That may be acceptable for occasional use, but if you rely on a battery like this frequently, build quality becomes much more important. Another limitation is the AC inverter. While the unit does include an AC outlet, the output is very low. Many devices that you might reasonably expect to work simply won’t run because the power output isn’t sufficient. It can handle small charging tasks, but anything more substantial tends to fail or shut down. In the end, I returned this unit and replaced it with the Jackery Explorer 240D. That model is almost three times the price, but it is dramatically better built and operates entirely through USB-C. It can both charge and output up to 100 watts through USB-C, which means it can power laptops and recharge very quickly using common cables. I use portable batteries like this every day for my work, so reliability matters a lot. After comparing the two, I kept the Jackery and returned this unit without hesitation. The difference in quality was immediately noticeable. That said, this isn’t necessarily a bad product if your needs are fairly light and you only plan to use it occasionally. But for frequent use or situations where you need something dependable, I didn’t get the impression that this unit was built to last. The battery chemistry and overall construction are adequate, but nothing exceptional.
