Overcharging is not good for the lithium-ion batteries inside your devices. This issue is the reason why companies like Apple have introduced charge optimization features in their devices. But many devices don’t have these types of protection — and their batteries can suffer if they’re left on a charge for long periods of time.
Now, Canadian company LAVA Computers has a simple and affordable gadget that claims to add years to your device’s battery life.

Claiming to be the ultimate battery protection for personal devices, LAVA’s Charge-Check is a compact, universal plug-and-play adapter that uses Continuously Active Battery Modulation to protect your lithium-ion battery from overcharge and bloating.
Features of LAVA Charge-Check
- For any USB charging device
- Featuring Continuous Active Battery Modulation (CABM)
- Requires a power supply capable of at least 5V, 2A (device charger recommended)
- Supports 9V, 2A fast charging
- Micro-USB to USB-A cable included
- 2 x status LEDs
Using Charge-Check is simple. You pop it in line with whatever device you’re currently charging, and it starts working right away.
There is a built-in default charging strategy, where Charge-Check monitors the charge level of the device using CABM (Continuously Active Battery Modulation) and charges the battery until it is sufficiently filled to the maximum. which is 4 hours.

At this point, Charge-Check will stop charging for a certain length of time, the default is 3 hours, before trying to top-up the battery again. According to LAVA, this is a good strategy because lithium-ion batteries have been proven to last longer when the battery charge percentage is kept in the 50-60% charge zone.
You can adjust the length of time — from 1 hour to 5 hours — with the button on the front, and Charge-Check can also be set to make one charge and then stop.

On the front of the Charge-Check there is a pair of LEDs that act as charging indicators, but if you charge things at night in your room, it can be annoying, so LAVA has a feature in night-mode that turns off these lights.
I have tested this device and it does what it says in terms of charge control, and it does so without overheating or causing any problems. In fact, it’s a great tool for taking care of things that you keep charging and recurring over and over again.
For example, on my workbench I have an LED light, a thermal camera, and a power bank that are constantly charging, and I feel that adding Charge-Check to the equation will help keep these devices’ batteries longer. long time.

Note that the output port of the Charge-Check is USB-A, and with the reduced supply of these cables, quickly replaced by USB-C, you will need to remove the old cables from your stash, or use a USB-A to USB-C adapter, which I tested and works well.
The only thing I can’t test right now is how much more battery life Charge-Check will give me. However, the way it charges is much better in terms of lifespan, and it’s much better than constantly piling power on a device. I think this device is perfect for devices that charge for a long time. This is definitely an innovative solution to a difficult problem.
