About This Product
Scigold 18650/21700/Li-ion Battery Charger with LCD Display
SCIGOLD smart chargers automatically detect the cell and apply the correct Li-ion charging profile. LCD display shows charging status and individual cell voltage in real time. Compatible with 18650, 21700, and other common 3.6V Li-ion cylindrical cells.
Frequently Asked
Quick answers, before you buy.
Can the CW401 charge both 18650 and 21700 cells?
Yes. The CW401 accepts 18650 and 21700 cells along with other common 3.6V Li-ion cylindrical cells. The adjustable bays accommodate the different cell lengths, and the charger automatically detects each cell and applies the correct Li-ion charging profile with no manual switches or settings required.
How many batteries can the CW401 charge at once?
The CW401 is a 4-bay charger, so you can charge up to four cells simultaneously. Each bay is monitored independently, which means every slot manages its own cell and reports its own status rather than sharing a single combined charging channel across all four positions.
Can I mix different battery sizes in the CW401 at the same time?
Yes. Because each of the four bays detects and charges its cell independently, you can mix sizes such as an 18650 in one slot and a 21700 in another at the same time. Every bay applies the correct profile for whatever 3.6V Li-ion cell it holds, so mixed loads charge safely together.
What does the LCD display on the CW401 show?
The LCD display shows real-time charging status and individual cell voltage for each bay. This lets you monitor the progress of every cell separately so you can see which are still charging and which have finished, rather than relying on a single indicator light for the whole charger.
What input does the CW401 charger use?
The CW401 uses a USB-C input, so it powers from common phone chargers, laptop adapters, power banks, and car USB ports. This makes it convenient for travel and home use alike, and removes the need for a proprietary barrel-jack power brick to keep the charger running.
Does the CW401 work with any Li-ion cylindrical cell?
It is designed for 18650, 21700, and other common 3.6V Li-ion cylindrical cells. The charger auto-detects the cell and applies the matching profile. It is intended for 3.6V Li-ion chemistry, so it should not be used for NiMH, NiZn, or non-rechargeable cells, which require different charging.
