XTAR PB2SL V2 Power Bank Charger

The XTAR PB2SL V2 2-in-1 Battery Charger & Power Bank is a versatile, high-performance device designed for outdoor enthusiasts, field professionals, and anyone who relies on rechargeable batteries for their gear. Unlike standard power banks, this unit doubles as a dedicated charger for 18650, 20700, and 21700 batteries—commonly used in high-drain devices like torches. Its dual functionality makes it an essential tool for both charging and powering devices on the go.

The device’s design is compact and travel-friendly, with a sleek, matte finish and magnetic front panel that easily detaches for quick battery access. This magnetic lid is both a convenience and a minor risk—while it allows rapid battery insertion and removal, it can open unexpectedly if the unit is dropped or mishandled. The internal cavity is fitted with a removable spacer that adjusts to accommodate different battery sizes, ensuring a secure fit for 18650, 20700, or 21700 cells. This adaptability ensures compatibility across a wide range of battery types, making it ideal for users with mixed battery setups.

Charging performance is where the PB2SL V2 truly shines. It supports advanced fast-charging protocols including PD3.0 and QC3.0, enabling rapid charging of compatible devices via its USB-A and USB-C outputs. The intelligent voltage balancing system ensures even charge distribution across multiple batteries, reducing stress on individual cells and improving overall battery longevity. The unit also features adaptive charging speeds—adjusting output based on the number of batteries being charged—optimising efficiency and reducing heat build-up.

A standout feature is the clear, real-time LCD display, which shows battery status, charging progress, and output voltage and current. This level of transparency gives users full control and confidence during charging and power delivery. Whether you’re powering a smartphone at camp or recharging a high-drain flashlight battery, the display provides immediate feedback.

Operation is notably quiet, especially in low-current mode, making it ideal for nighttime use without disturbance. Its durable construction, lightweight build, and compact footprint make it easy to pack in a backpack, emergency kit, or tool bag. While the device doesn’t come with batteries included, this allows for flexibility in choosing battery capacity and brand based on individual needs.
