Satte battery power on the go

The battery comes with a Micro-USB cable in the box. Due to its prismatic design and rubberized soft-touch surface of the battery is very good in the hand and takes with its dimensions of just 10x5x5 cm also very little space. On top of the device you will find the USB port connectors for the supply of 1A and 2.1A charging current, a micro-USB connector for charging the Thumbox Power Tube, and a white LED with a long press on the on / off switch is switched and takes over the function of an emergency flashlight. The device has a four-stage LED indicator that provides information about the current residual energy and during charging about the charging status information. This LED display is also operated via the on / off switch.

With a battery capacity of 7800 mAh the Tumbox Power Tube XXL does not go so quickly run out of steam: My Apple iPhone 4s, the fully charged Thumbox 2-3 times recharge fully again. Certainly can not perform miracles the device, because my fallen to 5% battery life iPad Air can only up to about 70% recharge the fully charged Thumbox again. This is a bridge to the next loading facility but more than adequate. WHILE the current output, the battery heats significantly but overall he is just a little more than lukewarm.

I can speak for the Thumbox Power Tube 7800 XXL only my wholehearted recommendation, which is reflected in the evaluation of full 5 out of 5 stars. The device is small, powerful and visually as well as haptically at very high levels. Especially when traveling I do not want to renounce the Thumbox.
