Keep four 18650 cells charged and ready between takes
A BMAX BH-18650-04 multi-bay charger you can hire to top up 18650 lithium-ion cells and other cylindrical Li-ion sizes.
Up to four bays charge at once on independent channels, each with a red or green status LED, all fed from a simple USB 5V input.
The BMAX BH-18650-04 is a multi-bay charger for 18650 lithium-ion rechargeable cells and other cylindrical Li-ion sizes.
It has up to four bays, so it charges up to four cells at once, with each bay running on its own independent channel.
That means a nearly flat cell and a half-used one can sit side by side and charge on their own, without one bay holding up the rest.
Every bay has a red or green status LED, so you can see at a glance which cells are still charging and which are full and ready to swap back into your gear.
It is powered by a simple USB 5V input, so it runs from a mains USB adapter, a power bank, a laptop or a vehicle USB port, and does not tie up a mains outlet.
Each bay charges at about 4.2V and 1000mA, and the spring-loaded contacts hold cells firmly while they charge.
The same cradle fits 18650 cells plus smaller Li-ion sizes such as 10440, 14500, 16340, 14650, 16650, 18350 and 18500, so one charger covers everything from small torch cells to full-size 18650 packs.
This is a charger only, so the cells themselves are not included unless stated. On a shoot or event, crews use it to keep spare cells topped up for torches, LED lights and camera grips so the kit never runs flat.
Why Choose This Product
- Charges up to 4 x 18650 cells: four bays top up a full set of cells in one go, so you always have a charged spare ready.
- Independent channels: each bay charges on its own circuit, so mixed-state cells can go in together without one slowing the others.
- Per-bay status LEDs: a red or green light on every bay shows charging or full at a glance, handy when rotating cells during a live event.
- USB 5V input: runs from any USB adapter, power bank, laptop or vehicle port, so it does not need its own mains outlet on a crowded rack.
- Wide cell fit: one cradle handles 18650 cells plus smaller Li-ion sizes, so it services several device types in a kit.
- Tested and ready: checked across all bays before dispatch, so you rent a working charger instead of buying one you use once.
How Can You Use This
- Recharge torch and light cells: top up 18650 cells for head-torches, hand torches and LED on-camera lights between takes.
- Keep camera grips running: recharge cells for follow-focus units, monitors and motorised grips on a shoot.
- Charge several at once: load up to four cells so a full set is ready when the on-set batteries run flat.
- Manage backup power: rotate two sets of cells through the charger during a multi-hour event so the kit never runs out.
- Power from anywhere: feed it from a power bank or laptop USB port when there is no free mains socket on the rack.
