You can recharge it normally, inserting it in a charger or recharge it like a mobile phone: inserting a USB-C cable!
The new Nitecore NL2150R is a revolutionary 21700 type battery: it is in fact designed with an integrated USB-C charging port so that it can be recharged directly using a USB charging cable (sold separately).
Just connect the battery to a available USB power source (for example to a PC or to a wall charger for tablet or smartphone) and a red light next to the positive pole of the battery will light up to inform you that the charging process is started. As soon as the light turns green, charging will be completed.
Alternatively, these batteries can be charged normally, like any rechargeable battery, i.e. using any external charger compatible with Li-Ion 21700 batteries.
Equipped with integrated intelligent charging circuits and other safety functions, this battery works in complete safety respecting the precautions indicated.
