A ADDTOP Solar Charger Power Bank - 25000mAh Fast Charging Portable Charger with 4 Solar Panels Solar Cell Phone Charger External Battery Pack for Phone Tablet Orange

Item came nicely packaged. Once unwrapped, it's solid and chunky in the hand, about the profile of a large phone but much thicker. Also simple to operate and waterproof enough to withstand a bit of rain - what's not to like?The large 2.5Ah capacity is a real boon: this will charge your phone several times, even keep your laptop going. The downside of course is that solar-only charging will take a looooong time - that's just physics; four tiny panels just don't soak up much sunlight. Once you place it in sunlight, though - even a cloudy, rainy British day through a window - the green "charging" light comes on, suggesting the panels are pretty efficient for their size.There are 2 x USB-A outputs so with adapters you can basically charge anything. (Input is USB-C letting you charge the bank from a wall socket.) For travel, in-car, or thrown into a bugout bag, this little device is truly excellent. Recommended.

Now had this for almost three years, it’s a wonderful piece of kit. You can charge it either through its solar array or by micro usb. It has a high capacity battery so I’ve found it can charge a standard iPhone several times or an iPad once or twice depending on how charged it is. Takes about 8 hours to charge to max from nothing via cable, or in the best conditions a few days via solar. All of this of course depends on the plug you’re using to charge it from or how sunny it is. I personally love it, so handy to have something that has the capacity to charge your phone when you’ve forgotten to, or with a few hours in the sun, can at least give your phone a bit of a boost to get it through the day. It also never gets hot when charging for the mains which I think is a good thing. It’s a larger power bank which can fit in a big pocket. As for toughness/ durability, it feels very solid, would help if there was a clip on the back for it to be attached to a rack sac if you’re out on a walk but ultimately it is practical.

This is a great little charger. It charges far better than chargers I bought before with a single panel. It DOESNT come with a carabina which is really not on, but once you have bought one (69p!), it hangs off your bag perfectly. The fabric and clip will break in-time, so next design could do with something in the structure to clip to, but thats just constructive feedback.The charger itself has far higher capacity than 20k charge, so holds a lot and can charge to max in a day from mains. Charges best in a car windscreen (solar), without being distracting to a driver, for use charging a phone while using satnav, but charges slower than usage (Still well worth it though as it uses less battery). Cable entry point hangs downwards so safe to charge 2 devices even in pouring rain while hiking, or sealed charge point if you prefer, nicely designedReally impressed with the quality of this, happily rivals Anker as similar physical size (but far higher capacity), great fold out solar panel and fast charging devices.

Not good battery is not as high as it advertised, solar panels don't charge the battery, and ports don't work as intended.States that the battery is 25000mah but is probably more towards 10000-12500mah. Left it to charge over the day in the sun (bright sun with very few clouds) didn't charge atoll. The usb A ports charge normally for a couple of minutes then either don't charge at all or charge extremely slowly. So the only good port on it is the usb c port and that still charges slowly.

Fantastic buy, a great price and conveniently equipped with multi solar panels for charging top ups. Perfect thank's 👍

I bought this item to take on holiday to Majorca, as I was going with family, and there where loads of phones and tablets etc that we had bought with us, these would all need Charging so the idea of a power bank that could charge it's self with solar was appealing, as there never seems to be enough sockets to plug in to when we are away.The item arrived and seems to be very well made. I changed it from the mains as per the instructions it took a fair time which is only to be expected for a item with such a big battery.I then used it to charge my phone, which was on about 30% this it did in a reasonable time the power bank was showing approx 50% after this, which I thought was a bit poor, although my phone also has a very large capacity battery.I have a number of power banks and they all seem to not have the battery capacity that you would expect I think it's probably down to power loss when they charge another device!As for the solar charging performance it is lacklustre as I said I was on holiday in Majorca at the time so very strong sun, ideal or so you would think. Firstly you can't leave the power bank out in very hot sun as it will over heat which is indicated by all the charging lights flashing! The specs say that the solar panel is rated at 6 watts well I would be surprised if it manages any where near that. I experimented with it and did the same when I got home and have come to the conclusion that it will recharge but it could take weeks or even months to recharge its self from say 30% to full and then only in ideal sunlight.I discharged the bank by approximately 2 amps and it took well over 4 days to return to full again in very sunny weather!It's not really the fault of the power bank it's just physics the solar cells are much to small to do what is claimed.So as far as solar charging is concerned if you where going off grid for any length of time you will need a device with a much bigger solar panel than this power bank has . I think it's fair to say the only thing you could use the panels on this power bank for is keeping it topped up once you have mains charged it as it takes forever to recharge after even small amounts of discharge!
