XTAR PB2SL V2 2-in-1 Charger & Power Bank Review

For the modern gadget enthusiast, managing a collection of batteries and power banks can be a cumbersome affair. The XTAR PB2SL V2 aims to solve this by elegantly merging a sophisticated Li-ion battery charger with a portable power bank, creating a truly versatile tool for on-the-go power. This clever hybrid promises not just convenience but also a level of control that dedicated power banks simply cannot offer.

The core appeal of the PB2SL V2 is its dual identity. It’s a competent two-bay charger for a wide range of popular Li-ion cells, including button-top and flat-top 18650s, 20700s, and 21700s (both protected and unprotected). The charging process is managed intelligently, with a maximum speed of 2A per bay. But slide in one or two charged batteries, and it transforms into an 18W fast-charging power bank, supporting both Quick Charge 3.0 and Power Delivery 3.0 protocols. This flexibility is its killer feature, allowing you to not only charge your phone or tablet but also to swap in fresh batteries for your flashlight or vape mod, all from a single device.

In terms of design, XTAR has made practical choices. The chassis is built from a durable, flame-retardant plastic that feels sturdy enough for a backpack but won’t win any design awards for its premium feel. The standout feature is the strong magnetic lid, which snaps on securely and prevents batteries from ever falling out accidentally. Inside, a small ribbon is thoughtfully included to help you easily pry out the cells. The small digital display is a massive upgrade over simple LED indicators, providing real-time data on battery voltage, charging/discharging current, and even the charged capacity, giving you a clear picture of your power status.

Performance is solid for a device of this class. As a power bank, it delivers on its 18W promise, rapidly charging a modern smartphone via either the USB-A or the bidirectional USB-C port. When charging the internal batteries, it provides a steady 2A to each slot, which is respectable but not the fastest on the market. One key feature that sets it apart from simple power banks is the 0V activation function, which can revive and rescue Li-ion batteries that have been over-discharged—a lifesaver for those with a large collection of cells. The only minor performance quirk is that when both output ports are used simultaneously, they default to a standard 5V/2A shared output, losing the fast-charging capability.

Ultimately, the XTAR PB2SL V2 isn’t for everyone. If you just need a simple, sealed power bank to charge your phone, there are slimmer and more straightforward options. However, for anyone who already uses 18650, 20700, or 21700 batteries for other high-drain devices like flashlights, cameras, or vapes, this product is a game-changer. It eliminates the need to carry a separate charger and power bank, consolidating your gear into one smart, reliable, and highly functional unit that offers unparalleled flexibility.
