Thanks to the integrated Micro-USB cable, all Android and Windows smartphones as well as tablets can be connected directly to the power bank, eliminating the need to carry an additional charging cable. Four blue LEDs indicate that the power bank is fully charged. When the battery is nearly depleted, this is signaled by the last status LED blinking. The power bank can be easily recharged using the included Micro-USB cable. Additionally, the power banks feature another USB port that allows any type of USB charging cable to be connected. This means that other devices, such as iPhones and iPads, can also be powered. With the S5000 power bank, it is therefore possible to charge two devices simultaneously. The slim power bank is equipped with a lithium-polymer battery, which allows for particularly fast charging of mobile devices thanks to a 2.0 Ampere output voltage. Due to its form-variable lithium-polymer battery, the S5000 power banks have a particularly slim design that can easily be placed under the smartphone. This makes the power bank easy to transport and it can even be stored in a jacket or pants pocket while charging the smartphone. The S5000 is available in black and white.
