On a full charge, the A2S can inflate two 700x25c road tyres from 0 to 80 PSI, or provide multiple top-ups for gravel and MTB tyres.
Does it work with tubeless tyres?
Yes. It is suitable for reinflating and topping up tubeless tyres after a puncture has sealed. It is not designed to seat a stubborn tubeless bead from scratch.
Is it waterproof?
The A2S is weather-resistant and can handle road spray and light drizzle, but it is not fully waterproof. Keep it protected during heavy rain.
Can I take it on cycling holidays?
The 500 mAh / 7.4 V lithium-ion battery is small enough for typical carry-on travel requirements, but always check the current airline and local travel rules before flying.
