Tired of having to run to the store to buy batteries every time they die? Me too. Until one day I discovered a hack that truly changed the way I use my remotes. And the best part? It’s simple, inexpensive, and incredibly satisfying to do yourself.
The battery puzzle: a small problem, a real budget
You know that moment: you’re settling down on the couch, ready to start your favorite movie… and your remote refuses to respond. Once again, the batteries are dead. Between the TV, the fan , and the kids’ toys, those little batteries add up to a surprising expense without us even realizing it.
So, instead of buying yet another pack of batteries , why not… replace them permanently ?
A homemade trick for a rechargeable remote control
The solution is surprisingly simple. Here’s what you need to turn your standard remote control into a rechargeable device:
- A small rechargeable battery (3.7V lithium type, such as a 14500 or equivalent)
- A USB charging module (type TP4056, easy to find on online sales sites)
- A diode (e.g. a 1N4007) to adjust the voltage if needed
- A little patience… and that’s it!
The idea is to remove the standard batteries and solder the battery wires in their place. You add a small micro-USB or USB-C port to the case (on the back, for example), and your remote control becomes rechargeable like a smartphone . Convenient, right?
And for the more curious: the Bluetooth version
Want to take things a step further? It’s even possible to convert a remote control into a Bluetooth-connected device . This option requires a bit more skill: you’ll need to integrate a microcontroller (like an ESP32) and completely reprogram the circuit .
This is another adventure, ideal if you like electronics and DIY . But if you just want to do away with batteries, the first solution is more than enough.
A small gesture for you, a real step for the planet
