Quite useful


I’d mainly like to see updates to make it fit the iPhone X display better. It also doesn’t work with my iPhone 4 but I guess that’s because of Bluetooth 2.1.

Needs development but has potential


Remote charging for this charger is a great feature and has a lot of potential! The qr scanner will also be great when it is fully implemented.

Currently all qr scans time out so even though a program is created and the batteries are labeled you are unable to scan your batteries to charge them. The scanner is also not included in the andriod app frustrating other users but I am assuming this will be implemented once it is working in iOS.

There is so much potential for data logging and tracking for each battery scanned. If the app could create a log with mah charged, volts before and after charge, number of charges ect users would be able to spot faulty batteries before there is an issue.

Overall a good start but the functionality isn't all there and the technology isn't being fully utilized. I am hoping that this will improve in the future!

Here is Work Around For Bugs in this App


So Hitec X4 is sold in US as Hitec but is sold around much of the rest of the world as SkyRC Q200 which is the exact same EXCEPT that SkyRC "SKYCHARGER" (yes, one word) app works perfectly, including printing and scanning QR codes. So do yourself a favor and skip this app and get "SkyCharger".

Old Review
Excited to use feature of newly purchased x4 ac pro where you set charging specifications, print QR Code generated by app, tape QR Code to battery and then scan QR code with iPhone to provide charger with charging settings in effort to reduce chances of kid putting in wrong settings and damaging battery or burning down house. Unfortunately does not work despite downloading repeatedly on different phones (6s and 7). When comes time to scan generated / printed QR Code, app errors out saying "request timed out". Hitec technical support is useless. Says first time they've heard of it. Apparently they don't read their own app reviews here or on internet. Will update if fixed. Other features work ok.
