Bests & Worsts Reviews from Amazon

Works like a champ. I was out camping in the mountains for 5 days no electricity. I followed instructions and made sure the unit had a full charge prior to first use. First night my cell phone was down to 10% and my tablet down to 5%. I turned them both off and plugged them both (at the same time) into the solar charger. When I woke up the in the morning they were both at 100% charge. During the day I left the solar charger exposed to the sun. Each night it charged my cell phone and my tablet to 100%. A word of caution.... if the solar charger has LESS battery life than what you're trying to charge it will suck the power out of the device you're trying to charge and suck that power into the solar charger. Make sure you have a full charge on the solar charger before trying to charge something else with it.
