Specifications

Everyday Use and Handling

Spring-loaded slots make inserting and removing batteries straightforward, and each slot is monitored independently, so one weaker or older cell will not affect the charging behavior of the others sharing the tray. The charger also auto-restarts a charging cycle if a resting battery's voltage drifts down over time, keeping cells topped up while stored.

Delivery Across Dubai & UAE

Vape Dubai King ships the Efest Lush Q4 with same-day delivery in Dubai and cash-on-delivery service extending to Abu Dhabi, Sharjah, and the rest of the UAE.

Frequently Asked Questions

Can the Lush Q4 charge 21700 batteries?

Yes, it supports 21700 cells alongside 18650, 20700, and other common lithium-ion sizes.

How fast does it charge?

Charging speed adjusts automatically based on how many batteries are loaded, reaching up to 2A when charging a single battery, and stepping down to 1A or 0.5A as more slots are filled.

Does it stop charging automatically once batteries are full?

Yes, the Lush Q4 cuts off automatically when a battery reaches full charge, helping prevent overcharging, and it will resume topping up a cell if its voltage later drops while sitting in the charger.

Can I charge just one battery instead of four?

Yes, each of the four slots works independently, so you can charge anywhere from one to four batteries at a time and the charger will adjust its output accordingly.
