This power bank won't let you down. Conventional power banks for recharging smartphones and tablets are often empty just when you need them. The Voltcraft SL-11 power bank has built-in solar cells that prevent self-discharge, as long as the power bank is stored in a suitable location (e.g., on a windowsill).

Light in the dark: 32 LEDs on the back provide impressive area lighting at the push of a button. This rechargeable light is always ready for use when stored, for example, by the window.

Charging status indicator: 5 integrated LEDs display the charge level at the push of a button.

Perfect for hiking and camping: The shock- and splash-resistant housing features a sturdy attachment loop for carrying or securing with a carabiner, for example, to a backpack. On the go, the LED light can be used to read hiking maps or simply as illumination at the campsite.
