VIFLY WhoopStor V3 6 Ports 1S LiPo Battery Storage Charger and Discharger with LCD Display Tiny Whoop Charger with PH2.0 and BT2.0 Connectors

The VIFLY WhoopStor 3 is the best in its area for charging 1s lipos, although it does have some faults which you should consider before purchasing.Its benefits include it able to charge 6 batteries at once (something I find very useful as I have 5 lipos), using a USB C input to charge, resulting in it being compatible with powerbanks, (if they have a high enough output power), or a wide range of chargers. The VIFLY WhoopStor 3 also charges relatively quickly, with the charging amperage and voltage being able to be customised.Despite the positives, you should keep in mind that it can't charge batteries some batteries, as one of my outputs broke after 2 days.So, if you would like a customisable and efficient product, choose the VIFLY WhoopStor 3. I would consider it to be the best 1s battery charger.

Great charger

Great product. Charges well no issues were found.

This is probably the best investment you can make for your whoop drone. Sure, it's a very expensive charger, almost as much as the charger you bought for your 5-inch FPV. But think of it this way: it'll eventually pay for itself.If you learn to manage your whoop batteries properly, you can dial in your own settings to protect them from overcharging and put them into a proper storage state. That makes your batteries last so much longer, which keeps you from constantly buying new ones. Over time, that adds up.Calling it a "fast charger" is a little weird, because you set how fast you want it to charge. If you want to stay within safe limits, you just keep it dialed in right. Power options are plenty too. You can run it off a USB-C fast charger or a 6S battery pack. Pair it with a 6S battery and you can take this thing anywhere, because it's seriously compact. It's not too heavy, and it'll keep charging even when there's no wall power around.The LCD gives you stats on each battery, shows which ones are charging and which are ready, and there's a loud beep when they're done. It's a must-have if you find yourself flying your whoop multiple times a day.So yeah, sure, it's a lot to spend on a charger that can pretty much only charge one type of battery. But it charges that one type of battery pretty darn good.So, 5 stars. It's an investment up front, but the battery savings, the portability, and the smart charging make it more than worth it for anyone serious about flying whoops.

Works how I expected it to, takes about 30 to 40 minutes to fully charge 6 batteries at full power to 4.35v. it's small which is convenient.
