[Upgraded] BigBlue Ultra-Light Portable 25W Solar Panel Charger with USB-A and USB-C Ports, 0.84 lbs Pocket-Size IP68 Waterproof, Folded Solar Panel Compatible with Cellphone,Power Bank,Camping Light

folds into small package, well made. Charged a 10,000 portable power bank in about 6 hours in the sun. Great back up item and small and lite. Highly recommend. Very well made, wish it came in a small case, has an elastic strap to hold it closed, but very happy with it overall

Quickly charged my phone with midday sun, or at sunrise and sunset. Just have to make sure the cells are 90° to the suns raise. It does add more weight than other less powerful solar charger, but the lower charging time is worth it, particularly at sunset, and much better on weight than a battery.

Immediately used this on a four day backpack trip and it performed very well. Had weather every day but enough sunshine midday to recharge my iphone, inreach mini and another phone.

This solar panel works really well! It charges about 1000 mAh per hour based on my very basic testing. I brought it with me on a 3 day backpacking trip, just to test it out. It packs up compact and is very easy to use. The price fluctuates on this product, so I recommend waiting for a coupon or price drop, to get the vest bang for your buck.

So small and light weight. Paired up with a small battery pack and charges all day then the battery charges the phone at night!

Zero stars, this product does not work. Wish I hadn't gone passed the return date before I realized it doesn't work.

Seems pretty decent so far. Will find out more when I go on a trip and will need to rely on this.

So the name of this solar panel is P25 and right in the title it says "25W" but do not be fooled that you will ever get 25 watts out of a single port. Its right on the box, maximum wattage from the USB-A port is only 12 watts and the USB-C port is only 15 watts max. Big Blue decided to add these together to make you think this can pump out 25 watts, which in perfect conditions perhaps it could give you the 12 + 15 watts but I've never seen that.In reality, using a solar panel alignment tool and the sunny skys in August in the midwest, I can only get 9-10 watts out of the USB-C port. USB-A port is 8 watts. If I plug an Iphone in the USB-A and an Ipad Mini into the USB-C port, the iphone charges but the ipad displays "Not charging" meaning the USB-C port doesn't have enough power output to even be considered a charger with two devices hooked up. If I charge the ipad by itself, it does charge.This is a pretty weak product for the price and should only be considered a 10'ish watt charger. You need to really value the compactness of this to pay this much.
