XTAR PB2S charges 18650 and 21700 batteries and doubles as a power bank with QC3.0 and PD3.0 fast charging. Real-time display shows voltage, current and battery percent, built for outdoor and emergency use in Kenya.
Product Description
One device instead of two is the whole idea here: the PB2S charges 18650 and 21700 cells through its USB-A and USB-C ports, and once those cells are charged, the very same battery feeds power back out to top up a phone or small device, turning what would otherwise be a single-purpose charger into a genuine power bank as well. That dual role matters most exactly when it's needed most, during a blackout or partway through a hike.
QC3.0 and PD3.0 fast-charging support apply in both directions, so charging the cells themselves and using them to charge something else are both genuinely quick rather than one direction being fast and the other left at a basic trickle rate. A numerical display shows voltage, current and battery percentage in real time, removing the guesswork around how much charge is actually left before a hike, a night shift, or a period without reliable mains power begins.
Convenience features
0V activation revives a cell that's been over-discharged past what most chargers attempt
Magnetic, dust-resistant cover protects seated batteries between uses
Built-in ribbon underneath makes cells easy to pull back out
Good for outdoor trips, emergency kits kept at home for load-shedding, and daily commutes where carrying one compact device genuinely beats the bulk of a separate charger and a separate power bank taking up two spots in a bag. It takes 18650 or 21700 cells specifically, both very common sizes across flashlights and headlamps in this catalogue, so cells bought for a Klarus or Convoy torch elsewhere will generally work here too.
