Product details

The PowerTank 20,000 is the ultra-compact, fast, and powerful battery charger from Cellularline for all occasions.

The PowerTank 20,000 is made with innovative lithium-polymer cell technology, allowing it to be 40% smaller than a traditional power bank with lithium-ion cells while maintaining the same performance.

This small yet powerful PowerTank 20,000 is ideal for always having the necessary energy on hand and quickly recharging your devices (smartphone, tablet, headphones, GoPro, drone, etc.) multiple times in a row.

Thanks to the dual USB-C and Micro-USB input, the PowerTank 20,000 can be charged directly with the USB cables of most common smartphones.

Additionally, the PowerTank 20,000 features a simultaneous fast charging system and overheating protection, allowing you to charge your devices comfortably and safely.
