A device to charge your smartphone at night without risk to you or the battery

Since smartphones have appeared on the market, there is a question that has plagued us: Is it OK to leave them charging overnight?


Although, it is indeed a very convenient habit, the answer to the question is that it is not advisable.

Owing to its characteristics, a lithium-ion battery tends to lose its efficiency every time it is allowed to charge to 100%. Moreover, this exposes the battery and us to risky overheating which, as news reports have confirmed, can have serious consequences.

Not to mention the environmental impact: By causing the battery to deteriorate ahead of time this means more electronic waste is produced, with obvious consequences for our planet.


However, an invention has arrived from Romania that can help us solve this problem without sacrificing convenience! It is the first charge limiter for smartphones.

Chargie, developed by Lighty Electronics, is a very small and intuitive device. It connects via Bluetooth and reduces recharging to the percentage that the user selects through the associated app.

Chargie is a unique device that opens the way to a more conscious use of technology, making it both safe for us humans as well as respectful of the environment.


The smartphone charge limiter Chargie is among the projects selected by  Maker Faire Rome – the European Edition 2019, the world-famous innovative technology fair that will be held from 18 to 20 October at the Fiera di Roma. Come discover it and a thousand other ideas!
