Efest LUSH Box Vape Battery Charger

Two bays, a built-in power bank, and a 2.1A charge rate that actually moves the needle. The Efest LUSH Box is a dual-slot 18650 battery charger that doubles as a portable USB power supply. Single battery charges at 2.1A; two batteries run at 1.0A per bay. Accepts flat-top, unprotected 18650, 20700, and 21700 cells.

 LED indicator shows charge status in real time; automatic cut-off at 4.20V keeps everything safe. If your Vape Mod takes removable batteries, this charger earns its spot.

Why vapers choose the LUSH Box:

• Charger and power bank in one unit. Two jobs, one piece of kit.

• Independent bay monitoring so mismatched charge levels are not a problem

• 2.1A quick charge gets a single 18650 back to full faster than budget 0.5A chargers

• Three battery sizes, no adaptors. 18650, 20700, 21700.

• Pass-through capability charges batteries and powers a USB device simultaneously

Efest LUSH Box Vape Battery Charger Features

Why Power Bank Mode Changes Things

Load charged 18650 cells, press the side button for two seconds, and the charger becomes a portable power bank with 2.1A USB output. If you carry spare vape batteries, you are carrying backup phone power too.

Zero Buttons, Zero Fuss

Slide the battery in, and the LUSH Box detects it. Single cell charges at 2.1A, two cells drop to 1.0A per bay. The LED shows charge progress without any input from you. Less to break, less to configure.

Built to Last

Fire-retardant housing, piano wire springs, low-resistance steel cathodes, and hard chromium plating on the contacts. That plating resists corrosion over hundreds of charge cycles. Browse Vape Batteries to pair with the LUSH Box.

Five Safety Systems

Reverse polarity, overcharge cut-off at 4.20V, over-discharge protection in power bank mode, short circuit, and over-voltage. Five layers between your batteries and trouble.

Auto-Balancing for Married Pairs

Run a dual-battery Regulated Mod? Unmatched voltages shorten cell lifespan. The LUSH Box brings both bays to matched voltage automatically.

How to Set Up the Efest LUSH Box Vape Battery Charger

1. Connect the Micro USB cable to the LUSH Box and plug into a USB source rated at 5V 2A or higher.

2. Insert your battery positive-end first. Spring contacts adjust to fit 18650, 20700, or 21700 flat-top cells.

3. The LED lights up and shows charge progress automatically.

4. Wait for full charge. A depleted 18650 at 2.1A takes roughly two hours.

5. Remove once charged. Auto cut-off at 4.20V prevents overcharging.

6. Power bank mode: insert charged cells, hold the side button for two seconds, and connect your USB device.
