Flexible, sustainable, powerful: The new Flex5 and Flex10 powerbanks with replaceable batteries quickly supply mobile devices with fresh energy


Solingen, Germany, October 2021 – Ledlenser is expanding its portfolio of portable power banks to include two powerful models with replaceable 21700 Li-Ion batteries with Flex5 and Flex10. Flex5 contains one battery, while Flex 10 uses two. Unlike conventional powerbanks with permanently installed batteries, the high-quality Li-Ion batteries can be conveniently exchanged and used in other devices without loss of time or capacity. The new powerbanks thus offer a secure energy reserve for mobile everyday companions, also for the Ledlenser P7R Signature flashlight or the H7R Core headlamp, for example. This ensures plenty of backup power, whether on trips and outdoor activities or during work assignments. The batteries can be transported safely and securely in the robust housing. A further new addition is Batterybox7 Pro, which serves as a solid storage for two 18650 batteries and in which the batteries can also be charged. 

The Flex5 and Flex10 powerbanks from Ledlenser

Both models quickly supply mobile devices with fresh energy via the USB-A port. They can be conveniently opened and thus serve as a stable storage box for the safe transport of the batteries. Even when on the move, Flex5 has one and Flex10 two batteries at hand, which are quickly charged at up to two amperes via Speed Charge. Both products feature a simple mechanism that makes it easy to open and close the box and thus remove the batteries. Furthermore, the powerbanks are easy to store, thanks to their space-saving shape. They also offer safety in harsh environments: the flame-retardant housing is IP65 certified, and all USB ports are also waterproof. The protective circuit board guards the energy dispensers against overvoltage, overcharging, short circuit or deep discharge. Thanks to LED indicators for each battery, the capacities always remain in view. The batteries can be easily replaced with fresh ones at the end of their service life, meaning that the longlife powerbank can continue to be used, this way the environment is protected.
