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

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.

For my fellow military folks like myself, this is a decent portable charger when you’re out in the field lol. It does as expected: charges your phone. However, i recommend you charge it fully on an outlet priort to any trip. The full charge can charge your phone fully about 2 times before you’d have to recharge on an outlet again. The solar charge does take quit a while to recharge and will only charge your phone about 60-80%. I had to leave my phone plugged charging while solar recharging and it did charge however took a while. Hope this helps.

FIts great in a backpack and can charge multiple devices at the same time. This battery will last you all day, or even multiple days if your judicious. The solar part of it does work, but don't think that it is going to be the daily way to charge it. I think of the panels more if I were hiking/camping or in emergency situations where you need to charge your phone. The panels will take hours to be effective.

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

This portable charger is a beast. It's about to handle 3 devices at a time, with 2 USB and one USB-C. When charging one device like my android phone, it can charge multiple times without having to charge itself, great quality. One drawback is it's heavier than some, but it's worth it in the end. The solar panels will charge the charger itself, but better to plug into a wall charger.

Got this for an uncle in Panama who lives off grid. He uses it to charge a cell phone and says it works well and the power bank charges pretty well with the solar panels.

I took it backpacking and was able to charge my phone six times on one power bank charge. It is a heavy for backpacking but I used a gps map so I was glad that I had it. I wouldn’t let the charge get very low before using the solar panels to charge the unit.
