The rise of mini electric pumps means it could well be game over for the dear old conventional mini pump. These tiny, portable devices are easier to carry while you ride and do away with having to pump like a maniac to reach your desired tyre pressure when you get a flat.
I started using the Cycplus AS2 mini electric pump last year, and since then, my selection of standard mini pumps have been gathering dust in my garage.
There are a number of mini electric pumps on the market these days. While some are cheaper than the AS2, it’s a model that’s never let me down and has saved many rides from deflating disasters. Now you can pick one up for less than $50 or £50 with this Amazon Prime Day cycling deal.
US – save $21.57 on the Cycplus AS2 and pay just $48.42.
UK – get a £20.74 saving on the Cycplus AS2 and pay just £40.25.
Measuring just 4.6 x 2.8 x 6.4cm (1.8 x 1.1 x 2.5in), the AS2 easily fits in the palm of your hand. At just 97g (3.4oz), it won’t weigh down your jersey pocket or riding pack, and I’ve even stuck mine in a trouser pocket on casual rides and commutes.
To use the AS2, I usually connect the unit directly to a valve stem. It does come with an inflation hose though, which comes in handy if the space between your wheel spokes is on the tight side.
The maximum pressure the AS2 can provide is 100psi, which is impressive for a tiny unit. In my testing, it took the AS2 just 60 seconds to inflate a 700c tyre to 50psi. It also has far less vibration than some of its competitors, so it’s easier to hold in place while you inflate. It’s not overly loud while it operates either.
Recharging the pump’s internal battery takes around 20 minutes. A full charge should be enough for two 700x25c inflations, but I’d recommend recharging the AS2 after every use. The pump comes with a silicone sleeve, a splash-proof pouch, and a USB-C charging cable.
