I bought this for a 5 day camping trip. In combination with the Anker battery pack it charged 4 phones twice and a DAB radio once and still had spare charge. Light, tough and easy to use. Be aware though; you can't charge the battery pack with the solar panels and re-charge your phone at the same time.
This is a good piece of kit. I struggled at times to charge our iPhones - but this was more to do with that annoying problem when an apple phone says it doesn’t support a piece of equipment rather than the charger itself. We overcame the problem by charging a power bank in dull weather over a day camping which then charged the phones overnight. You can charge two pieces of equipment at one time and a red indicator light shows when the unit is getting enough light to actively charge. Eyelets on the corners allow it to be secured to a car roof, over a tent, or the back of a rucksack. The 3 separate panels can be angled to a degree to capture the optimum amount of direct sunlight.
