But my phone keeps charging only at 100%?
Your phone stops charging at 100%, but the charger keeps supplying power all night, generating heat hour after hour near where you and your family sleep. VOLTCUT physically cuts off the power flow: it's not software, it's a real power cut. Your phone manages the charging; VOLTCUT cuts off the power. They're not the same thing.
Since I got it, I sleep peacefully.
My phone had been overheating every night for months. I changed the cable, I changed the charger, I tried turning it off before going to sleep. Nothing really worked. My sister told me about VoltCut because she used it and said it wasn't like the others. I bought it without much hope. A week later, my husband picked up the phone in the morning and said, "Hey, it's not burning hot anymore." He didn't say anything else, but that night he plugged it in with the VoltCut too. It's been three months and I haven't thought about it since.
Ahora ya no me preocupo por cuanto lo dejan mis hijos cargando.
Mi hijo tiene 16 años y carga el móvil toda la noche sin pensarlo. Empecé a preocuparme cuando vi que la batería ya no le duraba ni medio día con un móvil de un año. Lo compré para él, pero la primera semana lo probé yo en el mío. El móvil dejó de calentarse por las mañanas y la batería empezó a aguantar más. Ahora tenemos dos en casa y mi hijo ni sabe por qué su batería volvió a durar como el primer día.
Real tranquility, from real people.
The mistake you make every night without realizing it
Every year, thousands of house fires start in the bedroom for the same reason: a device left charging overheats hour after hour, without warning. Something almost all of us do every night without thinking.
Why we designed VOLTCUT
It's not carelessness: no one tells us that leaving our phones charging all night can be costly. We plug them in next to the bed, with the kids' tablets beside them, and go to sleep. But that current keeps flowing in and turns into heat that accumulates hour after hour, where the family sleeps, unsupervised.
FAQ
Yes. The main cause of battery degradation is continuous overcharging. Every night your phone spends hours charging after reaching 100% reduces its lifespan by weeks. VOLTCUT prevents this, and over time the battery maintains its capacity better. It's not magic; it's about not mistreating it every night.
Yes. VOLTCUT supports up to 140W and does not interfere with the charging speed; it simply stops it when it reaches 100%.
No. You plug it between your charger and your device, and that's it. No buttons, no setup, no app.
That's exactly what it's designed for. It protects any USB-C device, no matter how many hours it's plugged in.

Yes, it's compatible with any standard USB-C charger, whether it's for a mobile phone, laptop, or tablet.
Calm returns to your routine
There's a huge difference between charging your phone and charging it peacefully. You leave it on the nightstand and go to bed, like every night, but now there's nothing to watch: something takes care of it for you, silently, until morning. Because in the end, it's not just about charging a device, but about protecting what you have.
