【New Product】XTAR Visible Mixer VX4 Charger

Would be hard, can the MC3000 do that with Liion?

But overall yes, chargers with discharge current options of 1A or more are always welcome

That´s why I kept away from chargers with fan but maybe the S8000 will be my 1st with active cooling

Maybe they should follow the evolution of the PCs

In the past small fans with high rpm where used, now mostly 120mm fans where used. Low rpm, low noise, with good bearings also a good longevity because of low rpm

【Updated】The capacity grading accuracy of the VX4 charger

The VX4 charger uses a 300mA discharge current to test battery capacity. Compared with a professional capacity grading machine, its energy and capacity test accuracy is more than 95%. Under the comparison test of the XTAR lab, with the same test condition, a randomly picked XTAR 1.5V AA 1200mWh battery had real capacity 1161mWh by VX4 charger, and 1129mWh by capacity grading machine. The accuracy error between them is less than 3%.

And there is the VX4 real test by Admiral134 as below.

【Updated】XTAR VX4 Charger Review by Dr. Gough Lui

Thanks Dr. Gough Lui for the thorough review on the VX4 charger. “The XTAR VX4 is a very competent charger that can handle all commonly used rechargeable batteries. It reliably detects and handles 3.6/3.7V Li-Ion, 1.5V Li-Ion and Ni-MH automatically, allowing for a mixture of types of cells to be charged at the same time. The Grading results on the VX4 are within 2.0-2.8% (overestimate) of my lab-grade Rohde & Schwarz NGM202 which is sufficiently accurate for basic checks…”

That’s an excellent review! Very detailed. I learnt something new. :slight_smile:

i.e. 2% overestimate for capacity. Power supply with 12V output should be used for optimal performance. An adapter with PD might change to 9V.

【Updated】For charging NIMH AA/AAA batteries on xtar smart chargers

For charging NIMH batteries, our new chargers, such as VX4, MX4, L4 adopt pulse charging, and enable 0ΔV/-ΔV termination plus the CVSA technology, and other multiple schemes to intelligently determine when the batteries get fully charged. These charge algorithms ensure faster charging, higher accuracy of full-charge detection, and lower battery temperatures on NIMH batteries. Besides, the chargers have multiple protections, such as reverse polarity protection, Over-current protection, Over-voltage protection, over-charge protection, Short-circuit protection, overtime charging protection…

This is a joke? Even my smallest AAA/AA-chargers can charge NiMH faster than the VX4 :roll_eyes:

500mA only is the prove you not interested in NiMH-charging
