The XTAR Visible Mixer VX4 Charger is the first analyzing charger that can charge both 1.5V and standard 3.6V/3.7V Li-ion batteries, as well as NiMH and LiFePO4 batteries. This detailed review takes a look at this 4-bay charger’s features and ease of use.

Good conclusion, I agree with most Positives and Negatives.
Not sure why ppl like %, doesn´t help me a lot to imagine the current state.
To bad Xtar don´t use state-LEDs for the VX4, the LEDs of the VP4 Plus Dragon are very good visible.

I find % charged useful as a rough guide on charging status (I quite often pull batteries from my S4+ at 90% charge. But as we all know % charged is not entirely accurate. The VX4 is a fantastic consumer orientated charger that I would recommend to non-experts requiring a high quality charger. For enthusiasts and experts, there are better options.

For me is the voltage the better option, but for ppl who are not so familar with the typical voltages of the different cell-chemistries are maybe % better.
But there´s one thing with this charger which are not so good for Non-experts. I think like the VC4SL it will start with highest charge current which is available. I know that it´s sensitive about the IR but for Non-experts it´s maybe better if the default charge current is lower
I think the current control could be argued both ways. The way it is designed is very consumer orientated to reduce the amount of user Input required. It seems to do a very good job of automatically limiting current on smaller batteries or batteries with higher internal resistance. Personally, I prefer manual control with default low currents, but enthusiasts/experts are not really the target audience for this charger. Based on traffic to my website reviews of other chargers I would estimate that 90% of the charger market is non-enthusiast.

Not sure if small cells always have higher IR, I´m generally sceptical of automatic chargers, so maybe I´m an enthusiast

Am I correct in understanding that this only charges xtar branded 1.5v Li-ion batteries?

Thanks for signing up, Andanother!
Do you really want your email address out in the public like that?
It could attract spam emails.
1 Thank
No, it can charge any 1.5V Li-ion that has an integrated charging controller and expects 5V at its terminals.

Thank you for pointing that out. I have fixed it.
