XTAR VX4 Charger Review

The XTAR VX4 is a four channel charger with charging and grading modes. It supports 3.6V Li-ion, 1.5V Li-ion, 1.2V Ni-MH and 3.2V LiFePO4. USB-C PD (12V/1.67A) input is recommended.
The XTAR MX4 (Mini Mixer) can take a mix of four 1.2V Ni-MH, 1.5V Li-ion and 3.6/3.7V Li-ion batteries and charge them at the same time. There is also a special LiFePO4 Charging Mode for charging 3.2V LiFePO4 batteries.
The XTAR VC8S is an eight slot Li-ion and Ni-MH charger with USB-C PD3 and QC3 input. One of the main improvements over the XTAR VC8 is that the VC8S can use all eight slots for storage and capacity test modes. And I noticed that 26800 cells fit too!
XTAR actively participates in the torch enthusiast community across multiple forums and social media channels and they noticed a demand for a charger capable of handling a 26800 cell.
The display is easy to read. It shows the manually selected charging current, voltage and capacity. The tachometer-style screen looks cool, but I’d rather see larger numbers for the charging current and voltage.
