Norshire Mini is smallest tyre inflator

Norshire Mini is smallest tyre inflator

Many adventure riders and tourers carry a tyre inflator in case of a flat, but they can be heavy and bulky.

The Norshire Mini tyre inflator is no bigger than a torch and is claimed to be the world’s smallest, making it ideal to carry on your bike.

The aluminium cylinder measures only 208mm in length and 40mm in diameter and features a powerful cooling fan.

The Hong Kong company has launched two successful Indiegogo crowd-funding campaigns, raising almost $400,000.

They offer discounts to supporters.

We warn potential supporters of Indiegogo crowd-funding campaigns that they may not receive a refund unless specified. If the campaign does not, backers will have to contact the campaigner for a refund, put a stop to their payment or cancel their credit card.

Inflator for your bikeNorshire Mini is smallest tyre inflator

The inflator comes in several versions, but the one suitable for motorcycles is the Power Version with a Presta valve.

The Power version has 12 bar (174psi) of pressure and will pump 10 litres of air per minute.

They say it will pump up a motorcycle tyre in about five to eight minutes which is the limit of a battery charge.

It takes about 40-90 minutes to recharge the lithium iron phosphate battery.

You can charge it with a cigarette lighter or a 5V/2A adapter used to charge your phone.

They claim battery life of 3000 cycles of charging/discharging, compared with 500 for the Li-ion battery used in phones.Norshire Mini is smallest tyre inflator

You can also power the Norshire Mini inflator directly off a cigarette lighter output, but be aware this will also drain you bike’s battery.

Norshire Mini shows pressure in bar, psi, kpa and mpa and they say it is accurate to 0.2bar.

The built-in microcomputer measures the tyre pressure and automatically stops when it hits the preset pressure.

The stand-by power consumption is less than 1mA, so they claim it can sit idle for a year after a full charge without being over discharged.

Norshire Mini has four touch buttons for power, start/pause and +/- buttons to set the pressure.

It is powered by a high intensity ferromagnet 380 motor with 30,000 revs, 56W and 18kg of torque.Norshire Mini is smallest tyre inflator

They also claim the tight seal makes it quieter than most other portable inflators.

Their lithium iron phosphate battery works from -20℃, is less prone to spontaneous ignition and explosion than other types of battery and has a life of use up to seven years. It contains no heavy metals, rare metals or toxins.

  1. These mini pumps have been available, at least in the US, for in excess of 12 months. I say this because there were many makes available through Amazon, Ebay, similar outlets and other motoring associated shops when I last visited California in August 2018. All featured lithium batteries and a recommendation in their owner’s manuals was for the batteries to be charged every 6 months if left unused for that period. I took home 3 units and they are all working well. I have found their digital readouts to be accurate to better than 0.068bar (1psi). I gave 2 of these units to friends and retained one for myself. I use mine to maintain the tyre pressures in my cars, motor bikes, push bikes, the sack trucks, and whatever pneumatic tyres that are around. I used to put off checking and, as required, pumping up tyres. Nowadays, that is no longer a chore. I fact, it is now something that I look forward to, especially when a friend or neighbour seeks my help to pump up a tyre or two. The digital readouts and automatic cutout at preset pressures make these pumps a delight to use. On a full charge, each pump can pump up all 4 tyres of a medium sized car from 2bars to 2.3bars without showing any sign of slowing down. An indication of the significant amount of energy used was in the heat of the delivery hose. I found that the valve at the end of the delivery hose shown in the article did not work as well as that of the Shrader valve. Screwing and unscrewing the “Presta” valve connector usually caused some uncontrolled air leakage. In contract, attaching and detaching the Schrader valve caused no significant air loss. I can recommend such pumps to everyone because of the ease of use both in that they are light to carry around and in setting and achieving the desired tyre pressure. The convenience they provide means that all my pneumatic tyres are no longer neglected.
