About JIISO
JIISO is dedicated to developing high-quality electric air pumps for every cyclist.
We are committed to creating cycling products with technology and sustainability, to contribute to a cleaner and environmentally friendly world for ourselves.
Bringing a portable inflator with you is believed to be a must-have "self-defense item" for every cyclist every time they go out. After all, if you need to repair a tire or inner tube, you will inevitably be embarrassed because you don't have an inflation tool. However, portable pumps on the market are generally not small in size and light in weight, and they also have the problem of being inconvenient to carry. However, now we no longer need to "move forward with a heavy burden" like this. The compact, lightweight, and handy JIISO mini electric pump will solve this riding problem for us.
JIISO Electric Pump Features
The JIISO mini electric pump is made of an aluminum alloy valve and a nylon shell, and the actual weight of the whole machine is less than 100g. Compared with the size and weight of portable pumps, the advantages of its own lightness are obvious.
I believe everyone likes the compact and practical portable tool. Moreover, it only requires one button operation to start inflating. It is simple to operate and does not require time-consuming and laborious pumping.
Highly efficient charging and discharging energy: full charge in about 20 minutes
Before riding, you only need to quickly charge the JIISO mini electric pump with the provided Type-C charging cable, and you can travel with a full charge in about 20 minutes. Preparing before the trip and riding with peace of mind is simply a matter of preparation.
After multiple accurate tests in the laboratory, the current of a 300mAh battery cell in standby mode is less than 1UA. In other words, the JIISO mini electric pump’s almost power-free standby mode can accompany you for thousands of miles every day. There is no need to worry too much about the annoying problem of power outage of electronic products in standby mode.
With the high power and strong output of the brushless motor, this mini electric pump can pump two 700×25C tires from 0 to 80 PSI when fully charged. The 700×25C tire can be inflated from 0 to 60 PSI up to 4 times, and each inflation time only takes about 50 seconds. Of course, you can also crank a 700×25C tire from 0 to 100 PSI and it will do that very well.
The unique air nozzle design can adapt to AV/FV usage specifications and can be inflated to a pressure of up to 100 PSI. The air pump inflation port comes with FV (Presta valve) specifications from the factory and comes with an AV (Schrader valve) pin and seal. It is not difficult to quickly charge an empty tire in a short time with this mini electric pump.
The JIISO mini electric pump not only supports inflating bicycle tires but also can inflate small electric donkeys and sports balls. Compared with the lightweight mini electric pump products on the market, the price of this mini pump, which is as light as 100g, is very favorable.
