Features:

  • 【4 Port 2S Balance Charger with Storage Mode】You can balance charge four 2S batteries at the same time. And they are 4 independent charging channels, not necessary to ensure the batteries are all the same voltage or the same size. In addition to charging the battery to full voltage, you can charge or discharge it to storage voltage for long time storage.
  • 【Colorful LCD Screen, Intuitive Interface】VIFLY ToothStor installs high quality LCD screen, the charging status is displayed clearly and the intuitive interface makes the operation very simple.
  • 【Charge via Standard Balance Lead OnlyVIFLY ToothStor charges batteries via the standard balance lead only (JST-XH2.54), that conveniently eliminating the need to connect the power lead like XT30, T-plugs, etc..
  • 【Strong Heat Dissipation CapabilityThe fan and big heat sink would effectively dissipate the heat to prevent the unit from overheating. This greatly improves the efficiency and speed of the discharging.
  • 【Multiple Power Input】It supports Type-C, XT60 and DC power input. Type-C supports PD3.0 protocol that requests the input power must be higher than 65W.
  • 【Memory Function】VIFLY ToothStor had the memory feature of remembering last time settings, no need to set the charge current every time you turn it on.
  • 【Buzzer Indication】VIFLY ToothStor added the buzzer to beep when one charging circle finished, if you don’t like beeping, you can turn the buzzer off manually.

Doesnt work from cigarette lighter

Bought this to charge while driving. Made a cigarette lighter to XT60 cable and tried it out, but when the engine is running the Toothstor thinks the 13.5v is a 4S lipo and stops charging. I contacted support (twice), but no response. I guess i will have to buy a separate USB-PD power supply to use it.

Toothstor design flaw/suggestions

I don't normally write these but people need to be aware of this. Support won't reply to me after a week....

If you accidently even brush beep/voltage button your voltage settings will change to higher voltage and probably ruin your battery at best or cause a fire. The screen is obviously small so not easy to spot you have done this.

The button should be programmed so you need to press and hold the voltage button in order to change the settings IMO.

Secondly, it would be nice if you can change the max charge voltage on a custom mode for those of us that never charge to 4.2v on lipos.

As a charger it works fine, but because of this button it needs a firmware fix and then I'd give it 5*.

Great little charger

I got the one that only uses balance plugs. Good charger, like it as much as my ViFly 1s charger. Full featured including discharging to storage charge. Most excellent.
