- Four Individual Charging PortsYou can balance charge four 2S batteries at the same time. And they are four 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 longer battery life.
- Colorful LCD Screen, Intuitive InterfaceEquipped with color LCD screen, the ToothStor 2S Charger displays charging statuses with clarity, offering a user-friendly experience.
- Charge via Balance Port OnlyVIFLY ToothStor charges batteries via the balance port only, so you can charge any 2S batteries with JST-XH2.54 lead no matter it is XT30, T-plugs or any other power leads.
- Versatile Power Input OptionsIt supports Type-C, XT60 and DC power input. Type-C supports PD3.0 protocol that requests the input power must be higher than 65W.
- Efficient Heat DissipationThe 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.
- Memory FunctionVIFLY ToothStor 2S Charger had the memory feature of remembering last time settings, no need to set the charge current every time you turn it on.

Great charger! Can charge multiple batteries at the same time and also accepts different types of power inputs to power the charger. You can use either a 12v power source, 3-4s lipo, or a PD 3.0 powerbank to power the charger. Very nice! However not sure why a USB-A to USB-C cable wad included in the box. Most people in the US doesn't have a USB-A power brick that can support a higher voltage so it will not power the charger correctly giving a voltage error. Forgot to mention that the charger charges the battery via the balance connector. Works with majority of the batteries out there besides Thunderpower as they use a different balance connector. No need to worry about what main battery connector that is on the battery if you have different packs for different rc cars, planes, helicopters, planes, or boats. I can charge all my Losi Micro B batteries or put them in storage voltage. Perfect for smaller 350mAh-1500mAh battery packs. For batteries larger than 1500mAh you might want to use a bigger charger as the charge amps max out at 1.5a on the ViFly. Charger is very easy to operate with only 2 buttons. Has a built in fan that comes on automatically when needed. I would highly recommend this charger to anyone.

The media could not be loaded. being new to the RC hobby, I've acquired quite a few little 2S LiPo batteries, but they all just came with the little USB chargers, which just charge the batter up to full, and don't give you any info about the cells, and no options for safe storage. LiPo batteries require a little extra care, and should be charged to about 1/2 capcity for storage, They are most dangerous or likely to cause fire either during the charge process, or when at a full charge. Unfortunately charges that give info about the voltage of each cell or can put the battery in a storage charge tend to be quite expnesive, and that is often cost prohibitive or a hard price to swallow when you haven't invested that much into batteries yet. This charger solves amost all of that. I Feel it's an excellent vaulue for money. It's awesome to be able to charge 4 batteries at once, and I can see what the voltage is in each cell, which if 2 cells have very different voltages, it can be a sign the battery is about to fail or has other issues. This allows me to monitor the health of the batteries and cells. Functionality is fairly basic, basically 4 charge to volatages... 2 low voltages for storage of either 1. Standard 2S Lipo, or 2. LiHV Lipo. And same with the upper voltages, 1 for the standard Lipos, and a slight overcharge voltage for the LiHV batteries. Also can choose charge rate between 0.2a up to 1.5a. There's an option to turn an audible alarm on or off, which basically just chimes as a battery is done charging. It can discharge cells down to the safe storage voltage as well if say you didn't get to run a battery and it still needs to be discharged. It just discharges at 0.2a, so it can be a bit slow at that... but totally works. Basically runs the voltage off as heat and draws it off with the fan... so during discharge the fan will run constantly. During charging, the fan will periodically kick on or off to keep it's temperature low. Fan isn't very loud, but definitely audible. So far it seems durable enough... i've had it for a couple months and no issues yet. I like that I can use either a USB-C 65w power supply to charge it, or a DC adapter... or could even use another battery with an XT60 connector to charge things. I'd highly recommend for anyone getting started in the RC hobby with 2S batteries as a starter charger... and anyone giving their kids or someone a RC vehicle as a gift, this is inexpensive enough I'd recommend you get them one of these as well so they can properly charge and store their lipo batteries. Highly Recommend!

Great little charger been charging all size 2s batteries on it and no issues except it takes forever and also needs a high output 60watt and up charging block because it doesn't come with any charger

I use this for my micro bs, and my Trx4m batteries (with an adapter). I love it. Easy interface, compact size, charges fast. Really nice to be able to storage and balance charge these mini lipos; soooo much better than the crappy usb chargers that ship with most mini rc vehicles.

Great charger for 2S batteries. Simple, sleek, and works great. I really like that it can take a pack down to storage volts. That was #1 for me.

This tiny but capable charger sure beats having to drag out a bulky, high-amperage charger for smaller 2S batteries. It works well and balances individual cells perfectly. It comes with clear easy-to-understand instructions. The firmware update procedure using the Windows application found on the manufacturer website worked flawlessly for me. Something to be aware of: While it will discharge batteries to an appropriate storage voltage level, it does not include a setting to discharge down to a low voltage level for cycling or exercising batteries.

Very cool but still slow. *Think “safer”. But yeah..a couple hours to go from LVC to a fully charged 7.4 5200. No clue how long the 7200’s take..but it’s longer. Not necessarily a bad thing if you have plenty of packs to cover the charge time vs play time offset. Easy to use. Solid construction. Intermittent fan isn’t too loud. Doesn’t get too warm at all. Plus it’s mooobbbiiiilllleeee. Which is awesome. Only real gripe is that the leads on the batteries I use are maybe 4mm to short to let the battery rest completely on the table while plugged in/charging. Not a knock against this charger at all. Just gonna free-D print a big square with a rectangle cut-out for the charger.
