XTAR, a long-standing manufacturer of lithium-ion battery chargers, is pleased to introduce the PB2SL V2 – an updated version of one of our most popular products. Building on the original PB2SL, this new release continues to offer the dual function of charger and power bank, with several improvements based on real feedback from users around the world.

Since the launch of the PB series, it has gained steady support from our customers for its practicality and ease of use. It has also drawn attention across the industry, with similar products emerging from other brands. For us, this has always been a reminder of the responsibility we carry – to keep improving and to stay focused on what truly matters to the people who use our products.

With that in mind, our team has spent the past year reviewing user suggestions and working on technical refinements. The result is the PB2SL V2 – a product that charges more intelligently, operates more safely, and is easier to use in everyday situations.

XTAR PB2SL V2 Main Upgrade Highlights

✅ Smoother Operation

Users can now start the device by inserting either the battery or the adapter first — no fixed order required. The newly upgraded low-current mode, redesigned for easier access, is toggled with a double-click and keeps the screen on to show real-time battery status, perfect for charging earbuds and smartwatches.

✅ Safer Battery Management

PB2SL V2 introduces safer battery handling with support for safely replacing batteries during operation. It also features intelligent charging logic: single cells charge gently at 5V, while dual cells trigger fast charging after voltage balancing — helping protect battery health and extend lifespan.

✅ Enhanced Charging Performance

With up to 22.5W of output, the PB2SL V2 now supports a wide range of advanced fast-charging protocols including QC4＋, PD3.0, PPS, AFC, and SCP — ensuring broad compatibility with flagship models from Apple, Samsung, Huawei, and more. It can fully charge an iPhone 15/16 in about 2 hours and two 5000mAh 21700 batteries in around 3 hours.

✅ More Accurate Display

The upgraded display now provides real-time information for each battery slot, with a faster 10-second battery refresh rate. Screen timeout is adjusted based on the output port — 5 seconds for USB-C and 38 seconds for USB-A to reduce unnecessary energy loss.

Built for Real-World Scenarios

The PB2SL V2 is the ideal companion for anyone who relies on 18650 or 21700 battery-powered gear and values convenience, versatility, and reliability.

• Outdoor adventures: hiking, hunting, camping, overlanding

• Consumer gear: powering high-performance flashlights, radios, and audio devices

• Professional use: emergency response, security patrols, and mining operations

At XTAR, every product upgrade is guided by a simple question: “How can we make this better for the people who use it every day?” The PB2SL V2 is our answer to that question – a result of close attention to user voices and a reflection of our ongoing promise to develop chargers that are truly useful, reliable, and built to last.

We’re grateful for the trust and support of our users, and we look forward to hearing your thoughts on this latest update. PB2SL V2 is now available through XTAR official website and authorized partners.
