 20000mah Power Bank | ultra-slim 20000mah Power Bank- Sinoele 20000mah Power Bank


In design the ultra-slim 20000mah Power Bank is very well designed, clad in dark grey aluminium alloy with hard plastic screwed into either end. It feels reassuringly tough, and although it's heavy at 385g you wouldn't expect to cart around on your person such a high-capacity power bank for day-to-day use. Its dimensions aren't suited to a pocket, either.  


With 20,000mAh of power to hand, and an efficiency rate of  around 70 percent (some power is lost though voltage conversion and heat generated), the ultra-slim 20000mah Power Bank  will refill an iPhone 6 10 times, iPhone 6 Plus 5 times and a Samsung Galaxy S5 5 times. Exactly how many times it will charge your phone or tablet will depend on the capacity of its own battery, but expect at least 10000mAh to be available.


Of course, with two USB outputs you can simultaneously charge both phone and tablet from the Sinoele 20000mah Power Bank. With one rated at 5W and the other 10.5W, you can plug a phone or tablet into either output but the 5W port is better suited to smartphones than it is tablets.
