Efest LUSH BOX: a Two-Bay 18650 Charger and Power Bank in One
The Efest LUSH BOX is a pocket two-bay charger for 18650 batteries, with a lid, so it doubles as a carry case for your spare pair. It charges at 2.1A with one cell or 1.0A each with two, and balances the charge across a pair.
Once the cells are charged, the LUSH BOX also works as a power bank, running off the batteries inside it. It weighs under 200g, and an LED display shows each cell’s charge.

Which Batteries Does the LUSH BOX Charge?
3.6V and 3.7V 18650 Li-ion cells, one or two at a time.
Our 18650s – the Vapcell K25 18650, Sinowatt 25SP 18650 and Sinowatt 30SP 18650 – all fit the LUSH BOX, and it carries a pair of them safely between charges.
Will not fit: 21700s or any other size – the bays are for 18650s. For 21700s, see the XTAR VC2.
How to Use the Efest LUSH BOX
- Connect the LUSH BOX to a USB supply.
- Check each battery’s wrap first: never charge a cell with a torn wrap or a dent.
- Fit the 18650s the right way round and close the lid.
- Watch the LED display for each cell’s charge.
- To use it as a power bank, leave the charged cells in and plug your device into its USB output.
How Long Does Charging Take?
At 1.0A each, a pair of flat 2500mAh 18650s takes roughly two and a half hours; a single cell at 2.1A, a little over an hour. Allow a little longer for the final top-off.
Efest LUSH BOX Troubleshooting
| Problem | Likely cause and fix |
|---|---|
| A cell isn’t detected | Reseat it the right way round. Cells below 2.7V may need the LUSH BOX’s recovery function first. |
| The power bank runs out quickly | It runs off the two 18650s inside it, so its reserve is only as big as those cells. |
| A 21700 won’t fit | The LUSH BOX is an 18650 charger. |
| A battery gets hot | Stop charging and let it cool. Replace any cell that runs hot or has a damaged wrap. |

Charging Safety
Charge on a hard surface away from anything that could burn, never leave batteries charging unattended, and never carry loose cells in a pocket with keys or coins. Don’t charge or use a battery with a torn wrap or a dent. For dual-battery mods, keep cells as a pair: charge them together and replace them together. With the lid closed, the LUSH BOX is a safer way to carry a spare pair than loose in a pocket.
