How to Use the Golisi O2?

Here are the steps to use it safely:

Start by connecting the charger to a wall socket or USB power source. The LED indicators will flash briefly to show it’s ready for use.
Next, insert your batteries into the slots. This smart charger automatically detects the battery type and begins charging at the suitable voltage. Each slot operates independently. For example, you can charge a 18650 battery on one side and a 21700 on the other. The LED lights will turn red during charging and switch to green once fully charged.
If you’re using batteries for a high-drain mod like the Smok Morph 2 or Voopoo Argus XT, fully charge both cells before use.
Avoid leaving the batteries in the charger after they’re fully charged; even though the Golisi O2 charger for vape has overcharge protection, unplugging them after full charge is best practice for longevity.
