The new TSA airport traveling abroad rules require proof all electronic devices can power up or you will have to leave it there. So, use it for your phones, tablets, and cameras in airports, during prolonged power outages, while camping, boating, hiking, or any time you aren't or can't be near an electrical outlet. Our PowerStick has a unique Digital LED Level Indicator that shows the remaining charge present rather than having to guess with just LED lights. Wouldn't it be nice to know EXACTLY how much power you have left, in 1% increments? Compact, sleek design with a smooth finish and color that looks and feels elegant. Solid aircraft quality aluminum case protects the internal components from damage. It is perfect for purse, pocket, backpack, or briefcase. It comes in a nice gift box also.

Features built-in safety protections with SmartCircuitry to prevent Over-charging, Over-discharging, as well as Overcurrent, Overload, and Short-circuit faults. These valuable features protect your expensive device being charged. Both Input and Output is rated for a full 1A for quicker charging and discharging (charging your device).
