Best wireless rechargeable dash cams

Start with the Cobra SC 220C. It's the most complete package here: a 1440p front camera plus an interior-facing camera, motion detection, and it's sold by several stores, so you have real choice on where to buy. It's the one I'd put in most cars.

Who the others suit:

• Kenwood DRV-A310W — if you want a small, simple single-camera setup with Wi-Fi and Bluetooth for phone playback, from a brand with a long car-audio history.
• AZDOME M550 Pro — if you want three channels (front, cabin, rear) and GPS stamped on the footage, in one unit.
• Rexing C2 Pro 4K — if you want 4K front footage and a dual-camera setup; note it's rated modestly by the few reviewers so far.
• ROVE R2-4K DUAL — if you want a well-known dual 4K setup and don't mind a single seller.

One honest caveat: none of these is truly "wireless and rechargeable" in the sense of running untethered — dash cams of this class draw power from the car's 12V/USB socket, and their internal batteries only hold enough charge to save the last clip when power cuts. If you specifically want a battery-powered, no-wiring unit, say so and I'll look for that class.
