Efest LUSH Q4 4-Bay Battery Charger

Description

The Efest LUSH Q4 is a four-bay intelligent lithium-ion battery charger designed for common removable rechargeable cells used in vape devices and other compatible electronics.

It automatically adjusts charging speed based on how many batteries are installed, with up to 2A charging for one battery, 1A for two batteries, and 0.5A per battery when charging three or four.

Basically, it handles the charging-current math for you, which is convenient because nobody bought a battery charger hoping for extra homework.

• 3–4 Batteries: Up to 0.5A each

Each bay is monitored independently, allowing batteries at different charge levels to be charged together.

Important Battery Safety

Use only compatible rechargeable lithium-ion batteries that are in good physical condition.

Do not charge batteries with:

• Torn or damaged wraps
• Missing or damaged positive-terminal insulator rings
• Dents or crushing
• Swelling
• Leaking
• Severe corrosion
• Other visible physical damage

Do not leave lithium-ion batteries charging unattended or overnight.

Four charging bays are useful. Four questionable batteries being charged at the same time is considerably less useful.
