2UUL PW04 16-in-1 Android Power Cable

Android repairs bring a long tail of battery connectors, and keeping a separate power lead for each is impractical. The 2UUL PW04 gathers 16 labeled connectors onto one cable for powering Android boards from a bench supply.

The PW04 is a 16-in-1 Android power boot cable from 2UUL. The listing names brands including Huawei, OPPO, vivo, Xiaomi, Samsung, Tecno and Infinix, and claims coverage of 80% of Android devices. It has a 1 m cable with a pure copper core, TPE insulation and a pair of red and black alligator clips.

When the PW04 is the right lead

• A dead Android phone that needs a battery-free boot test.

• Checking current draw to find a short.

• Soldering or BGA work that needs steady power.

• A damaged or swollen battery that can't be used for testing.

Getting it right

Match the labeled connector to the phone before connecting anything, set the bench supply to the phone's battery voltage and start with a low current limit. The listing mentions built-in protection against shorts, but the current limit is what saves a board from a mistake.

Some Android boards won't boot without a battery ID signal. If the board powers up but reports no battery, pair the cable with an ID buckle such as the 2UUL PW06.
