Efest LUC V4 Elite Charger Review
The Efest LUC V4 Elite Charger is a four-bay charger with an HD LCD screen that shows each battery’s charged capacity, current and voltage. It charges Li-ion and IMR batteries, including 18650s and 21700s, plus NiMH and NiCd cells, and has a 5V 1A USB output. See more from Efest or browse all battery chargers.
LUC V4 Elite Highlights
HD LCD Screen
The screen shows the charged capacity, current and voltage of every battery at once. Efest says it turns off after 30 seconds without activity.
Up to 2A
Li-ion batteries charge at up to 1A each in all four bays, or 2A each in two bays. NiMH and NiCd cells charge at 0.25A or 0.5A.
USB Output
A 5V 1A USB port charges a phone or other device while the charger is plugged in. Efest says it also works as a power bank, using a Li-ion battery in bay 4.
Built-In Protection
Efest lists 0V activation, reverse polarity and short-circuit protection, automatic over-charge and over-discharge protection and error reporting. A reversed battery or a short makes the screen flash ERROR for that bay.

|---|---|
| Li-ion and IMR, up to four | 0.25A, 0.5A or 1A each |
| Li-ion and IMR, two | 2A each |
| NiMH and NiCd, up to four | 0.25A or 0.5A each |
The 2A rate is for Li-ion batteries only, in bays 1 and 4.
Batteries
Charge only rechargeable Li-ion, IMR, NiMH or NiCd batteries, never alkaline or other single-use cells, and don’t leave the charger unattended while it’s plugged in.
How to Use the LUC V4 Elite
- Plug it in: connect the 12V 2A adapter from the box to the charger and a wall outlet.
- Load the batteries: insert each battery with its ends matching the + and − marks in the bay.
- Watch the screen: it shows each battery’s voltage, current and charged capacity. If it flashes ERROR, a battery is in backward or there’s a short.
Who the LUC V4 Elite Is For
It suits vapers who charge several batteries at once, including 18650s and 21700s, and want an LCD charger that shows each one’s charge. For a smaller USB-C charger, see the Slim K4.
Good to know: It charges batteries only from its 12V adapter. The USB port is an output, not an input.
