2UUL PW06 19-in-1 Android Battery Buckle

Power an Android board straight from a bench supply and it may still refuse to cooperate: it reports no battery, shuts down at 0% or throws a heat warning, because the board can't identify what's connected. The 2UUL PW06 solves that with small battery buckles that carry an ID resistor, so the board sees something it recognizes as a battery.

The PW06 is a set of 19 battery connector buckles from 2UUL, labeled A1 to A19, for mainstream Android models from brands including Huawei, Xiaomi, Samsung, OPPO and vivo. Heat shrink tubing is included.

When the PW06 makes the difference

• A board reports 'battery not detected' on a bench supply.

• A phone shuts down at 0% or shows an overheating warning during testing.

• The phone's battery is damaged or removed and you still need to boot it.

• Soldering work needs steady power with the board recognizing the source.

Matching the buckle

The listing doesn't publish a model chart for A1 to A19, so check the photos or the included labeling against your phone's battery connector before relying on a buckle. Seat it squarely; a half-engaged connector can give the same errors you're trying to rule out.

The PW06 is a connector, not a power source. Pair it with your power cable and bench supply, set the voltage for the phone and keep a low current limit until the board boots cleanly.
