The PB2S Charger by XTAR doubles as a Li-ion battery charger and a power bank. The PB2S Charger allows you to charge 18650 and 21700 batteries and vape kits with internal mAh batteries. Enjoy QC3.0 + PD3.0 dual protocol fast charging which lets you quickly and conveniently charge your vape kit, vape batteries, mobile devices and mobile accessories anywhere at anytime. Type-C and USB-A ports may be simultaneously used to charge two external devices at one time and each battery slot charges independently of the other. 

The PB2S is made of a durable metal making it dustproof and shockproof. A single button located on the side of the charger adjusts information displayed on its LCD screen and shows the percentage the battery is charged in addition to number of voltage and amps used to charge the device.
