USB-C Rechargeable AA Lithium Batteries 1.5V 3400mWh

The remote goes quiet, you pull out the spent cell, and instead of reaching for a fresh pack you plug a USB-C cable into its cap.

Every orange cell in this set has a small USB-C socket sunk into its blue end cap. No separate dock, no hunting for a charger that fits: the cable you already use for your phone does the job. When the cell is full, it goes back into the remote, the speaker or the smart lock like any other AA.

The body prints AA and 1.5V in a blue label, and 3400mWh in large white figures along the side. Beside the port you can read the printed input rating, 5V/0.4A max, and a warning panel runs down the other face. The cells are orange with blue caps, easy to spot in a drawer and easy to tell apart from the disposable ones.

Key Benefits

• USB-C in every cell Plug a USB Type-C cable straight into the cap of each battery and recharge it in place.
• Standard AA size The label reads AA 1.5V, so the cell drops into the compartments built for the AA size.
• 3400mWh printed on the body The capacity figure is on the cell itself, large enough to read at a glance.
• A reusable alternative One set replaces the pack of disposable cells you keep buying for remotes and gadgets.
• Choice of 2 pack or 4 pack Pick two cells for a single remote or four for a speaker, a lock or a toy.
• Wide device range Suited to remote controls, portable speakers, smart locks, drones and electronic toy guns.

Best for: households and hobbyists who go through AA cells in remotes, speakers, smart locks and battery powered toys, and who would rather recharge from a USB-C cable than keep restocking.

Why It Works

The charging circuit lives inside the cell, so the only accessory is a USB-C cable. The maker lists the voltage at 1.5V, the same as a standard AA, which keeps the cell compatible with devices that expect that figure. The printed 3400mWh and the 5V/0.4A max input give you the numbers you need before you plug in.

Quick Product Facts: lithium rechargeable AA cells; 1.5V; 3400mWh printed on the body; USB Type-C port in each cell; printed input 5V/0.4A max; storage temperature -20°C to 55°C; sold as a 2 pack or a 4 pack; packing list: lithium battery per unit plus a USB Type-C charging cable.

How It Fits Your Routine

Keep the spare cells on the shelf next to the cable. When the living room remote fades, swap in a full cell, then put the spent one on charge while you carry on with your evening.

The same set rotates through a portable speaker, a smart lock or a drone controller. Each cell is charged on its own, so a four pack can be topped up one cell at a time from any USB-C source that matches the printed rating.

Between uses, store the cells at the temperatures the maker lists, from -20°C to 55°C, and read the warning printed on each cell before the first charge.
