Unique-Bargains AA Battery Case 8-Slot DC Connector 15cm Wire 4-Pack

Compact 8-slot AA holder with DC plug

Each moulded case holds eight AA cells and ends in a 15 cm lead terminated by a 5.5 mm by 2.1 mm DC connector. The pack supplies four identical holders so several projects can be powered at once. Batteries are not included and the cases have no screw terminals. The enclosure measures 58 mm by 30 mm by 62 mm.

Hobbyists needing quick battery power

Makers building portable sensors, LED strips or breadboard circuits can snap in standard AA cells and plug straight into a DC jack. The short lead keeps wiring tidy inside small enclosures. Users who need screw-down terminals, on-board switching or a different barrel size should look elsewhere. The note also warns against using the box for charging or shorting the leads.

5.5 mm by 2.1 mm DC output

The fixed barrel connector is the single detail that decides fit — it only matches gear with that exact jack. If your project uses a different diameter, pin size or polarity you will need an adapter or another holder. The 15 cm wire length and 1.5 V per cell are fixed by the design.
