MARBERO M822

I bought this for my business as I do a lot of night time markets. This little thing has come in handy. This little thing has lasted me 2 weekends on a single charge. I use it for lights and my phone charger. I would say the battery is good. Its very small and lightweight Easy to carry. I don't use the light on it but from my test it has 3 different modes, including the flashing light.

Excellent little battery! Maintained running several LED lights and a small light projector for over 6 hours with no apparent battery depletion. Used the built in lights extensively and recharged multiple devices like flashlights, phones, and tablets with very little battery depletion. This currently has exceeding my expectations and has turned out to be perfect for what I was looking for. Highly recommend.

Bought this for camping/backpacking given small size. Has enough battery for a week long trip powering multiple phones several times. Takes a bit to charge but is worth it.

UPDATED: Company ultimately issued me a replacement unit which solved the problems I was experiencing. Still bummed my first unit had problems but appreciate getting quality service, and conceptually love this product and the idea of having a portable laptop / cell phone battery bank. ORIGINAL: I'm a professional sound recordist and bought this (along with a solar panel by same company) to be able to recharge laptop, phone, and other small electronics while in the field. On paper it's great, I like the compact design, the flashlight is a nice feature, and it has a ton of ports. The problem is that my model seems to suffer from unpredictable, sudden battery charge loss. E.g. sometimes it behaves as expected (I've done a ton of recharge for the watt-hours of my devices and this battery, so understand what I'm asking of it) - other times the battery will either self-discharge and go from 4 bars to zero, or start recharging a cell phone and then totally fail. As a result I don't consider it trustworthy to bring into the field and unfortunately that's kind of a deal-breaker for a device like this. I'll be contacting the manufacturer to see if they'll offer a replacement battery, but I'm not sure I'll be able to trust it again which is a shame. If you're a professional and have low tolerance for this device failing, I'd purchase something else. But if it's a fun toy for recreational use, this will probably work for you.

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.

Works pretty good. My sister bought me one and I use the power generator with a small heating pad and it last about 5 hours on the lowest setting when camping. I liked it so much that I bought me another so I can have another 5 hours of heat from heating pad. It fully charges in about 6 hours with charger and a few hours more with the solar panel.

Top, we zijn erg blij met de powerbank en gaan hem uitproberen tijdens de vakantie!

Solido e pratico , facilissimo da usare. Consiglio adattatore Tedesco per presa sopra come da foto, comprato da Cinesi. Per ora positivo Poi in seguito sì vedrà. Pagato €118

La estación de energia es muy útil. La tenemos siempre en el coche por si algún dia estamos fuera y no tenemos energía, ya sea para cargar el teléfono, ordenador portatil.. etc.

Vraiment ultra pratique pour la maison ou les déplacements. Se recharge très rapidement sur secteur et un peu moins vite sur panneau solaire. Le moins : ne peut pas se recharger sur un autre panneau que celui de la même marque car un embout adaptateur ne fonctionne pas.

Pretty surprised with the product, of course it's limited capacity means it won't last long at full blast, but for charing multiple phones, a small fridge, it gets the job done. Think if it as a roided up powerbank.
