CONXWAN Solar 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

When looking for larger capacity charger power bank, I stumbled across this one and was intrigued by the solar charging capability. Being that it is a newer product without too many reviews, I figure I’ll take the time to say that I would recommend this one! There is a little bit of weight to this charger, but I believe it is from the larger battery paired with a good build quality. I’m especially impressed with how premium the solar panels look, especially with the leather material. They also function as expected; in the sunlight a green charging indicator light turns on. I’m pleased to say that upon arrival, this charger was already fully charged. So far I’ve topped off my iPhone 12 numerous times and charged a few smaller USB devices. The capacity lights still show that this thing has a long way to go before it’s empty! I’m excited to bring this with me on beach trips, I’m confident that with the sun and this 30,000mAh power bank, I’ll never be left without a charge.

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)

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.

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.

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.

This worked well for the first year. Solar charging is slow but was able to keep up charging a phone every few days for a backpacking trip. After a year the capacity started to drop, max of 2 phone charges. Then at a month over 2 years the battery swelled and broke off the panel and is completely dead. This is the shortest lifespan I have had from a power bank

The solar charging feature works well This a great little device for recharging phones and ipads. When I was doing extensive cross country flying I kept one in my flight bag in the cockpit. Why - The cell phone is a great aid in finding people in the wilderness. It is not just the call feature . In situations like the New Orleans hurricane where power was out, cell towers were down the message service will work in the tinyest bit of space on the cell network. But the cell phone is useless without a source of power . A more casual use is to simply know that I could keep the phone and ipad fully charged working on remote sites. Mine stays in the trunk of the car.

Helena & mostly Milton knocked out power here in Florida for few days and my 25000 Mah power brick only lasted so long decided I needed another one. Testing video on YouTube showed devices like this with multiple solar panels charger more than single ones like my 25000 Mah with one panel charged only 10%. Nothing fancy about this with only 3 ports in/out and no great flashlight but has a 27000 Mah capacity. Well see how well it works out but solar panels aren't very efficient in first place but if like my other one if it works to 10% x 4 that will be enough power for me.
