Designed for those who are on the go, the Celestron Elements PowerTank GO Charger is an outdoor portable charging solution for your electronic gear. Its 2-in-1 ergonomic design features a white LED flashlight with low/high light, flashing, and SOS modes, as well as a 7800mAh battery that can charge virtually any device that is compatible with USB up to two times, such as smartphones, tablets, MP3 players, and more. Device charging is accomplished using its 2.0A USB Type-A port, and when this battery pack is drained, it can be recharged using its 1.8A micro-USB port via your computer's USB port or an AC adapter. The PowerTank GO's overall battery capacity and charging progress can be monitored using four blue LED indicators.

As Celestron has built this device to withstand life outdoors, its outer shell is protected by a durable and rugged rubber housing. It is both crushproof and shockproof, and is also able to withstand drops of up to 15' and downward pressures of up to 1,000.0 lb for two hours. Additionally, it is dust and water resistant, with an Ingress Protection rating of IP-65. Protection is provided by a limited two-year warranty that is valid from the original date of purchase, with the purchase receipt needed for validation.
