Love my solar power charger!it charges really fast. Would definitely purchase again


Great product


Great time shipping was great it was fast it was on time and it works great

Jen G

Im charging my phone right now with this charger. Its super fast and I reach for it when I dont have a lot of time and need to charge my iPhone 11 quickly. The battery life is still good and Ive owned it now for a while and have used it at least 5 times per week each week. I dont have a charger on my bedside so this is what Ive been using over night. Its also relatively small and lightweight as far as charging banks go and I always bring it when I travel. Its easy to operate. You can easily see when its charging your device. You can also easily see when the charging bank itself is charging with the Paw on the front, each toe indicates a bar of power so to speak. I cant think of anything negative to say. I havent had any issues with it and would highly recommend it

Laura Breckenridge

It was worth the buy! The charge lasts for multiple days and can support multiple devices. I carry it when Im out in the town and traveling overseas. I havent used the solar function, I can imagine that it would take some time to get it to charge that way.
