With this powerful extra battery you can conveniently charge small and large mobile devices on the go. Ideally, you charge the Sunnybag POWERBANK 10,000 beforehand with clean solar energy via a SUNNYBAG solar charging system. When the sun isn't shining, you can also charge it conventionally via a socket or PC.

The LED display shows you the current charge level of the battery pack. Simply press the power/function button on the side and the 4 LEDs show you the charge status. Flashing blue indicates charging. When the blue lights stay on continuously, the battery is fully charged.

• 10,000 mAh capacity (Li-Po battery)
• Dimensions 90 x 60 x 22 mm
• Weight 190 grams
• USB-C cable included
• 1 USB-C input
• 1 USB output (2 amps at 5 volts)
• High-quality TPE surface
• LED charge status indicator
• Overcharge protection – switches off automatically as soon as the connected device is fully charged.
• Omnidirectional Powerflow – OPF technology enables efficient, simultaneous charging and discharging of the POWERBANK. This is particularly handy if you want to collect and use solar energy with a solar panel. Some devices cannot ideally handle the fluctuating current from a solar panel, so we recommend connecting a SUNNYBAG power bank with OPF technology in between. These have 2 charging coils – one efficiently stores the solar energy, while the second evenly passes the stored energy on to connected devices at the same time. This way, they are supplied with solar energy safely and continuously.
