This panel really hits the sweet spot between the huge, impractical fold-out panels and the little wallet-sized panels that will hardly keep a flip-phone charged. This panel kept mine and my wife's phone charged through 8 days of backpacking, including heavy use for navigation and audiobooks. 3-4 hours in the sun was enough to fill a smartphone battery (Galaxy S5) completely.
I take this 3.5 watt charger with me when I go to Mongolia. Since many of the places my wife and I visit in Mongolia are very remote, one can't rely on having any source of electricity to charge batteries with. The 3.5 watt charger will charge my cellphone, double AA batteries and my wife's point and shoot camera battery with no problem at all. Small enough that it will fit on the dashboard of a car while traveling from one place to another so it can be charged while driving. I use the charger at home as well since it is very convenient. Don't be caught without one!
