DeadEyeVR Valve Index Wrist Mounted Battery Kit - Accessory That Charges Your Controllers While Playing

These straps are either loose, or too tight. The battery falls out of them EXTREMELY EASILY, they leave horrible horrible marks on your forearms/wrists and they hurt like hell. I genuinely feel like a lady after taking her bra off when I take these off after using them to assist charging my controllers.

These things are awesome for those really long play sessions in VR.

I'm a streamer and having this is a great idea, able to extend my game play on VR for extra hour or 2 is amazing, At first I was worried these would be too small but when I got them and put them on they are amazing.

So these are awesome but only because no one else sells anything even close to this design for VRC. They are good quality, but be aware they aren't particularly comfortable to wear for extended periods and there is only a tiny percentile of battery banks that will actually fit them these days.

They work great for what they are designed for. Comfortable, relatively easy to strap on, fit my lipstick batteries snug without movement, and the provided cables are perfect length. Recommended for any long sessions that you need extra life from without having to sit down and charge.
