I used this item to upgradrade my Jumper T16 1st generation to a T16 pro hall v2. Everything worked as expected. Thank you Grayson Hobby for fantastic support!

It repaired my jumper thanks

Easy to install, and works perfectly. Great price too.

Kudos to Jumper for providing a low cost upgrade to existing hardware and not just telling customers to spend to buy new. Kudos to Grayson for providing an informative instructional video on YouTube. My battery has been kept topped off during my stay-at-home flying and sim time.

Just as it should be

Great addition to a great transmitter. Following Grason Hobby’s video made installation of the charging module quick and easy with basic soldering required. My November 2019 version of the T16 did not require widening of the USB slot in the top cover to accommodate the USB-C socket. Charging is now a breeze without removing the batteries. Great flow of information regarding the Jumper T16 from Grason!

Works great. Wish it had a charge indicator! I use a USB voltage stick that shows voltage and current going to the transmitter from the USB power supply. Lets me know when it is fully charged. Other than that, easy to install.

Ordered a month ago from backorder. Received a email saying it was being shipped. Got a tracking number. Tracking says pre shipment. Can't get any response from grayson hobby. Not happy. Where is my product?

Sorry to say but this is cheap in every sense of the word. Never worked out of the box. Plugged it into my MacBook Pro and nothing, no light no charge.
I feed back to ask for a refund for something that is only a few bucks so I will suck this up but stay away - this is not worth your money even if only a few bucks...for reference I am an old hand in soldering and wiring up electronics so this was no challenge but the result is disappointing .
