Ring RTC2000 Rechargeable Compact Cordless Handheld Tyre Inflator 3.7V review
Drivers who want a lightweight, glovebox-sized inflator for routine top-ups and breakdown cover, without running a lead to the 12V socket.

The RTC2000 trades outright capacity for convenience: it's small enough for a door pocket, works with the engine off, and doubles as a torch and USB power bank. Its own battery is the limiting factor — Ring doesn't publish a capacity or charge-time figure, so budget a handful of top-ups before it needs a recharge, and it suits occasional use and emergencies rather than a car that regularly needs a full refill from flat.

- No cable and no need for the engine running, with none of the accessory-socket fuse risk that corded 12V inflators carry
- Doubles as a USB power bank and LED torch
- 4-setting pressure memory with autostop removes the guesswork
- 100 psi / 6.9 bar ceiling limits it to cars, bikes, and small inflatables, not high-pressure kit
- Battery capacity isn't published and the hose is a short 14.5cm, so expect limited reach and only a handful of top-ups before a recharge
Who shouldn't buy this
Don't buy this if you need to inflate several tyres from flat in one session, or want something that plugs into the 12V socket and can run continuously — a corded 12V inflator holds up better for that.
