malykh.com notes: TOPUMP TB2 Pro: Tire inflation tests

2026-09-13

I ran some tests with the TOPUMP TB2 Pro electric pump to see how long it would take to inflate tires before the pump ran out of power.

I waited 60 seconds between each attempt to allow the pump to cool down slightly.

#1: 0 to 2 bar for 1 min 27 sec

#2: 0 to 2 bar for 1 min 42 sec

#3: 0 to 2 bar for 1 min 51 sec

#4: 0 to 0.8 bar for 38 sec, and it's over.

Another tire after fully recharging the pump.

#1: 0 to 3 bar for 1 min 41 sec

#2: 0 to 3 bar for 2 min 01 sec

#3: 0 to 1.8 bar for 1 min 28 sec, and it's over.

So, with a fully charged pump, it is possible to inflate an MTB tire two to three times (from zero).
