My viper v2 pro won't charge or turn on

I would try contacting Razer Support but it could be a longshot that they send you an entirely new unit (worth a try tho at the very least), otherwise I would just go out to your nearest local authorized Razer Retailer/Reseller and buy a new mouse.

The closest model that you may like would be the Cobra Pro, its got 3 connection types, that being USB-C Wired (the USB port in the mouse is the USB-C part), 2.4GHz HyperSpeed Wireless and Bluetooth Wireless, AND it has all the RGB flair too. The Cobra Pro is also compatible with the Mouse Dock Pro which is a neat thing if you decide to get one.

I will give you a fair warning that it may not be suitable for larger hands tho as its size is a medium to small sized mouse compared to what you’re used to. The Cobra Pro is a little smaller but not by very much than the Viper V2 Pro in size (it basically replaced the Viper Ultimate/Mini).

Just be sure you update the firmware on the Cobra Pro right away when you get it unboxed and hooked up to the computer because the Cobra Pro (and some others) just recieved a huge major firmware upgrade on November 6th which truly enhances the experience further with the mouse because Razer includes some nice fixes and enhancements to it. To my knowledge, the Cobra Pro mice that are on the shelves right now were shipped with the original release firmware onboard the device, so updating the firmware to the latest version is a super crucial step to do after purchase of the Cobra Pro to have the best possible experience with it.

P.S. Be sure to temporarily disable any AntiVirus software to do the firmware updates as these can conflict with Razer’s Firmware Updater programs.
