This lithium-ion battery charger has four battery slots, each of which is individually monitored. When the batteries are fully charged, the charger immediately stops due to short circuit safety. It’s a great match with 26650 batteries. They charge without the use of brick and come with a USB power cable. The charger itself is attractive, and the connectors, like those on most battery chargers, are spring-loaded.
There are excellent blue lights on top of this vape battery charger, and the slots are a lot broader than on other chargers. The indicator illuminates white when you put the battery in, indicating that the batteries are ready to charge. This Q4 charger charges at a rate of 2 amps. Multiple batteries can be charged at the same time. The charger will charge at 0.5 amps once all four batteries are connected, which is quite convenient. This is a basic 4-slot battery charger that is lightweight and easy to transport. It does not come with a power brick, which makes it an excellent traveling charger.
