Wynnsoft Dual USB Waterproof Solar Battery Charger - Blue

It charges my phone decently fast and my phone maintains the charge as if I used a wall charger. I only wish that the charger would replenish every time it was in the sun. It only charges when the charger is off. But besides that, it's super convenient and I love it!

Meh, was hoping to love this, but it's just ok. Will only charge my phone one time from a full charge. I haven't had enough chance to see how well the solar charging works.

The worst "solar" battery in the world (no I haven't tested every single one in the world). It doesn't charge in the sun. When I say it doesn't charge, I mean it doesn't charge in the sun or even charge anything plugged into it. If that were the only issue I wouldn't even being writing this review. Now when I charge it manually through the USB port it won't hold a charge long enough to charge 1 phone. If I were Amazon I would stop selling this garbage to your patrons.

Sturdy, neat idea for charging the kids electronics, especially on the go.

It won't recharge my Plantronics Bluetooth headset. I threw my money down the drain with this purchase.

it does not work

Love this

I've been using this charger with my iPhone 6 for about a week now and I am impressed so far. The build and quality is better than expected and the charge is quick and efficient. I was surprised how quickly it charged my phone via USB and how much charge the unit still had after each charge.I needed a smallish, solar unit for hiking and camping so the weather proof and rugged build was a necessity.I'll update this review after I go and use it in the woods, but the pre-wilderness testing has proven that it will do the job quite well.
