Rainbow Candy VIHO Supercharge 20k

Each VIHO Supercharge 20K comes pre-filled with 21 mL of e-liquid at 5% (50mg) salt nicotine, and it is not refillable. When the e-liquid is gone the device is finished. It is intended for adults 21 and over who already vape or smoke.

The VIHO Supercharge 20K recharges over USB-C. It runs a 650mAh battery. Plug it in when the vapor starts to thin, which usually means the battery rather than the e-liquid. A full charge takes well under an hour and the device keeps its e-liquid throughout.

The VIHO Supercharge 20K has a battery and e-liquid display, so both levels are readable at a glance rather than guessed. Flavor fading and a faint burnt taste mean the e-liquid is genuinely finished. A blinking light on its own usually just means it needs charging.

It runs a dual mesh coil, which is what keeps the flavor consistent from the first puff through to the last rather than thinning out partway. Nothing about the coil is user-serviceable on a sealed device.

At a typical 400 to 650 puffs a day, 20,000 puffs works out to about 4 weeks to 8 weeks. Heavy all-day vaping brings that down considerably, and lighter use stretches it well beyond.
