❓ How does VoltGuard work?
VoltGuard sits between your charging cable and your device. It monitors the charge and is designed to physically interrupt the power flow once your device reaches 100%, adding a hardware layer of control on top of your phone’s software.
The mistake you make every night without realizing it
Every night, millions of people leave their phones, tablets, headphones, and devices plugged in while they sleep. The device may reach 100%, but the charger can continue supplying power, creating heat hour after hour near your bed, your furniture, or your family.

FAQ
🔋 Does it really extend battery life?
By cutting power at 100%, VoltGuard helps your battery avoid sitting at full charge under constant power all night — a habit that can contribute to long-term battery wear.
⚡ Does it work with fast charging?
Yes. VoltGuard is designed to pass your charger’s power through normally, so your device charges at its usual speed until it reaches 100%.
✅ Do I have to do anything special to use it?
No apps, no buttons, no setup. Plug VoltGuard into your device, connect your usual cable, and charge as you always do.
👶 Is it safe for my children’s mobile phone?
VoltGuard was designed with families in mind. It adds a layer of protection against overcharging and helps reduce overheating risk on any USB-C device, including kids’ phones and tablets.
📦 Product material?
VoltGuard is built with a durable, heat-resistant casing and quality internal components, designed for everyday overnight use.
🔌 Does it work with any charger?
Yes. VoltGuard works with standard USB-C chargers and cables — the ones you already own. No special charger required.
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, but now there’s nothing to watch. VoltGuard helps take care of the charging for you, quietly, while your routine stays calm.
Why we designed VoltGuard
It’s not carelessness. No one really tells us that leaving devices charging all night can become a daily risk. We plug them in beside the bed, next to the kids’ tablets, or near furniture, and go to sleep. VoltGuard was designed to bring a simple layer of control and peace of mind to that routine.
But my phone keeps charging only at 100%?
Your phone may stop charging at 100%, but the charger can still stay active. VoltGuard is designed to physically interrupt the power flow, giving you a real cut-off layer instead of only relying on software.
Real tranquility, from real people.

Since I got it, I sleep peacefully.
My phone had been overheating every night for months. I changed the cable, changed the charger, and tried unplugging it before bed. Nothing really worked. Since using VoltGuard, I finally feel like my phone is charging safely overnight.
