Most vapers prefer to box mods that are powered by replaceable batteries since you can replace them easily without affecting your vape time. But if your battery charger takes too much longer time to fully charge your batteries, that would also be annoying. So you need a fast smarkt charger that can shorten the charging time. Now with the release of Golisi O2, you get the perfect choice. It's a highly intelligent battery charger, featuring a 2A fast charging, USB port, light indicator, intelligent circuit and auto power-off function. Two 3000mAh 18650 batteries can be fully charged in less than 3 hours. And it's compatible with almost all rechargeable batteries on the market. Its portable size also makes it very convenient for you to take it on the business trip or holiday. Available in EURO Plug and US Plug
