The ultimate battery protection for personal devices, LAVA’s Charge-Check is a compact, universal plug-and-play adapter. Compatible with virtually any USB charging device, Charge-Check leverages Battery Modulation to protect your lithium-ion battery from overcharge and bloating. If you leave your device plugged in, it is capable of overcharging, which strains your lithium-ion battery. Over time, this causes ion decomposition, off-gassing, and ultimately, battery swelling. The Charge-Check uses Battery Modulation technology to deliver power when you need it, and stop when you don’t. This helps you maintain the health of your battery, adding years to the life of your device. Use it with a 9-volt fast charger or a standard 5-volt one to protect your favourite headphones, smartwatch, and more.
