[Review] XTAR VC4L: USB-C nimh, nicd, li ion (21700 capable) multi speed charger

I received the VC4L from XTAR for the review.

The VC4L is a 4 slot battery charger, with a digital display, USB-C input. It can charge li-ion (including protected 21700), nicd and nimh batteries. It is able to reactivate batteries with a tripped PCB.
It represents the evolution of the previous VC4, and adds 21700 compatibility and USB-C input.

Here’s the video review of this charger, including video footage of the display and the animations.

The VC4L comes in this box

Inside the box, the VC4L is protected by this nice plastic bag.

The VC4L comes with instruction sheath, usb-C cable and manual.

The VC4L is 115 mm wide, 34 mm tall and 154 mm long, for a weight of 234 grams.

On the back of the VC4L there are the specs of the model

The slides can fit batteries up to 78 mm in length, and are smooth and easy to operate. The contact points at the positive side are 2 raised portions, allowing both for contact with flat top cells and with smaller cells.

The same goes for the negative contact points

On the top there is the usb-C port for input.

The charger has both a large display and a multi colored LED on each channel.
The LED on each channel will be
Green, when in standby, battery full, polarity inversion
RED: charging, reactivating the battery with a tripped PCB, diagnosing the battery

The VC4L is able to output 0.5 A on each channel, or 1A on channel 1 and 4 at the same type.
The display is backlit, and has a wide viewing angle. The backlit can be turned off by keeping the switch pressed.
The display shows the voltage of 2 batteries inserted, and the charging current of one channel (1 to 4, you can scroll them with a press of the button in the middle of the channels).

My thoughts
The VC4L is a simple charger with a big display that helps you understand what’s going on with the cells you are charging.
The charging current can’t be changed with a switch, but you can pick between 2 1A slots or 2 0.5A slots (or 4 0.5A slot when using 4 batteries).
The wide range of cells supported is good, but 0.5A can be a bit too high for smaller non IMR batteries.

Here are all my reviews on BLF

Thanks for the review. XTAR need to update their analysing chargers with longer slots.

From what I know, these Xtar chargers can test capacity:
- Xtar VP4 Plus Dragon (fits only up to unprotected 21700 batteries, discharge current seems to be 0.25A and 0.50A)
- Xtar VC4S (fits only up to unprotected 21700 batteries, discharge current is 0.3A)
- Xtar VC8 (fits protected 21700 batteries, discharge current is 0.3A)

I’m not sure if Xtar has any other analyzing charger models though.
