CONXWANSolar Charger Power Bank – 27000mAh USB C Solar Phone Charger with 3 USB Outputs with 4 Foldable Solar Panels Battery Pack Charger Compatible with Most Smart Phone

Great device, a little heavy but carries a lot of charging power. Splashproof and solar charging. Very very easy to use for its size.

I’ve bought solar chargers that stop working after a month.Bought this back in January of 2024.It is now April 2025. I used mine at least four days a week for about two hours a day, and after a year and change of constant use, the solar panel finally stopped working at max efficiency. Still works as a charger block, but definitely high quality for the price.

Needed a battery charger to use primarily for my phone and watch and this surely meets or exceeds that need. I like the idea that it’s more versatile than other offerings and the solar panels were an (although gimmicky) nice plus.Functionally it works well and I’m able to get several full charges of my devices out of it. It also recharges via a wall outlet reasonably quickly. I’ve only tried the solar charging once, but as suspected, it’s more gimmick than truly useful. Though, in an emergency situation or on an extended camping trip it may come in handy I guess.My only real beef with this thing is that the led status light is -really bright-! Like annoyingly so! And there is no way to dim or disable it.Additionally, my previous experience with the more inexpensive devices like this is that the batteries they include degrade rapidly over time. (When compared to some other offerings). This is especially the case if you aren’t able to maintain regular charging intervals even when the battery pack is not being used to charge other devices. Happy to say that, So far, this has been holding up with only semi regular charging/discharge cycles. But remains to be seen how much life the battery truly has.All in all, I’ve been pleased with it and hope to continue getting use out of it.

This is a big and solid power bank, and the build quality is pretty good.One drawback of most single-panel solar charging power banks is that they are very slow on recharging, which this one tried to combine four to boost up the speed, and it works. Still, the charging speed is not ideal but at least it is usable when you are outside. The solar panels are wrapped with leather-like materials and can be easily folded/unfolded.The LED light, although I have to say that the one I got is not the best quality (I can clearly see some dark corners), is still a good addition. It offers two brightness levels and slow/fast flashing. And since the power bank is thick, it can actually stand up by itself which makes it more useful.And yes, I said that it is thick. The power bank is big and heavy, so it is definitely not something you will want to carry around with you all day, you are exchanging the portability for battery capacity, so I will only recommend this to those who are going for any outdoor activity or use it as a stationary battery pack (I am using it to power my portable tracer for drawing)

I got this to take on a summer vacation and when it arrived it was certainly heavier than I expected. I wasn't sure how often I would use it but I found I used it often, sometimes to run a USB fan, sometimes to charge a phone. It never went flat and usually never dropped below 3/4 charge per overnight use. It does take a while to charge fully, and I never used the solar recharging side, but I am quite impressed with the performance. It is certainly a lot more powerful than my previous power bank.This one is right up against the max TSA carry-on size and it weighs a bit, but if you need reliable multi-use power this was perfect.

After being without power for five days during the May derecho, I wanted to add to my power bank collection. Having an option that could recharge outside seemed to make sense. When Hurricane Beryl made landfall just a few weeks later I was prepared and able to put the CONXWAN Solar Charger 27000mAh power bank to the test. Before the storm I charged it by plugging in to bring it up to full charge. After our power went out, it charged my Samsung S22 a couple of times, plus a full charge to my Kindle Fire and was only at about 50%. I put it outside in the sun for about 8 hours and it was back up to full charge. I'm not sure exactly how long it took, but it was ready to go when I brought it inside. I'm hoping it's a long time before I need to put it to work again.

The main feature that this battery pack totes over most others are the solar panels. But whereas the competition actually produced close to the rated 6W in full sun, this one only produces a less than 2W (1.67W to be exact) vs the claimed 12W (which is not even possible with this size array and current technology). On top of that, the usable battery capacity is only 57wh vs the almost 100 claimed.

The power bank part is good. I thought maybe since it has 4 panels then the solar charging would be good, but it stops charging 10-15min because it overheats in direct sunlight. The power bank part has inadequate thermal protection. If the panels were disconnected and the battery bank could be protected then the solar charging would probably work. 4 stars for the basic power bank portion, 0 stars for solar charging. You'd have to be in 35 degrees weather for this to not overheat probably
