USB Rechargeable AAA Batteries – Pack of 4 (Charging Cable Included)

Because constantly replacing batteries is a classic student life annoyance.

These USB rechargeable AAA batteries are the simple upgrade that saves money and reduces waste. Instead of buying disposable batteries every time your remote, mouse, or gadgets run out, you can just recharge these and keep using them again and again.

Plug them in, charge them up, and they’re ready to go. Much easier on your wallet, especially when you’re living on a student budget.
