XTAR PB2SL V2 22.5W Dual-Slot Fast Charger & Power Bank Case - Smart USB-C/USB-A Output with HD Display for Li-ion 18650, 18700, 20700 & 21700 Batteries (DIY Capacity, Not a Built-in Power Bank)
Description
【Product Description】
Turn your own 18650/21700 batteries into a high-speed 22.5W power bank! The XTAR PB2SL V2 is a revolutionary dual-slot charger and DIY power bank case that gives you complete control over your power needs.
Unlike standard power banks with fixed internal cells, the PB2SL V2 allows you to insert your own 18650, 18700, 20700, or 21700 Li-ion batteries, customizing your capacity on the fly. Whether you need a lightweight everyday carry or a heavy-duty outdoor energy reserve, you simply swap the batteries.
It features an upgraded 22.5W fast charging output and supports a wide range of protocols (PD3.0, QC3.0, AFC, FCP, SCP, PPS). The intelligent charging algorithm can balance two batteries of different capacities, maximizing their lifespan. The integrated high-definition display clearly shows your battery's remaining power, voltage, and current in real-time.
CRITICAL NOTE: This is a DIY power bank case. It does NOT have built-in batteries. You must insert your own 18650/21700 Li-ion cells to use it as a power bank. If inserted in reverse, the built-in intelligent system will alert you.

【Frequently Asked Questions (FAQ)】
Q1: Is this a power bank with built-in batteries?
A1: NO. The XTAR PB2SL V2 is a DIY power bank case and charger. It does NOT have built-in batteries. You must insert your own 18650, 18700, 20700, or 21700 Li-ion batteries to use the charging function.
Q2: Can I charge my phone while the batteries are charging?
A2: Yes. When plugged into a power source, it charges your batteries. When unplugged, it acts as a power bank to charge your devices via the USB-C or USB-A ports. This is called "two-way" fast charging.
Q3: What if I insert two batteries of different capacities?
A3: No problem! The PB2SL V2 features a smart balancing algorithm. It will safely charge both batteries with the appropriate current, maximizing the lifespan of both cells.
Q4: How do I know the battery status?
A4: The high-definition digital display shows real-time data, including the remaining capacity percentage (%), voltage (V), and current (A) for each inserted cell.
Q5: How do I get the flat-top 20700/21700 batteries to fit correctly?
A5: The V2 model includes a dedicated spacer bracket. Simply attach the spacer to the flat-top battery and slide it into the slot to ensure perfect contact with the negative terminal.
