Mini Bicycle Pump, Electric Bicycle Pump with Digital LCD Pressure Gauge, Ultra Small 120 PSI Bicycle Air Pump, 500 mAh, Type-C Rechargeable Battery Mini Pumps for Bicycles

A bit on the noisy side but performs great!

I've been considering buying an electric pump for a while but was put off on a cost/benefit basis, particularly as cheaper options did not include a pressure gauge and as I ride a variety of bikes (road/gravel/TT) each bike tyre needs a different psi.This pump seems to work well, fully charged it inflated a 43mm gravel tyre to 45psi in roughly a minute from flat and used 1 of the 4 "bars" of charge.It's also quite loud but I think all of this type are?I used the screw in extender with the presta adaptor without issue but noticed the "head" which the extender screws into did get very hot. The silicon cover prevents any heat transfer but worth bearing in mind and I'd suggest letting it cool down before using again or be aware if stowing in a back pocket.If you're after a more affordable option to carry instead of a pump/mini pump for emergency use, I thinks it well worth considering.Hope that assists 👍

Don’t buy this , it doesn’t actually inflate a tyre tried when needed it and it failed on me.

Arrived on timeSecurely packagedEasy to useTried it out on old bike tyreWorks well

Didn’t inflate tyres so sent it back got a refund paid a little extra and got a different one

I was disappointed with the presta value connection which you can only use with the connector so something extra to carry. What concerned me the most is that the unit becomes very hot in particular the screw connectors at the top which means you are unable to put the unit away until it has cooled down.

Thought it was very poor, didn’t hit required tyre pressure. It appears to be a one hit per charge, not too useful for wilderness. I will stick to hand pump.

The components supplied did not fit a Presta valve!
