Back in the 1900s, inflating motorcycle tires meant hand-pumping or making a trip to the gas station. When the bike’s battery died, we were rummaging for jumper cables and a power donor. I still remember how impressed I was four years ago when I plugged an electric tire pump into my battery tender—it felt revolutionary.
Today, we’ve seen significant leaps in portable device tech. Cordless inflators and compact lithium jump starters are now commonplace, making garage work and trail rides a lot more convenient. Already familiar with separate cordless inflators and jump starters, I was eager to test the Lokithor JP400, which merges both in one compact device. It delivers on many fronts.
Lokithor is a Chinese company that’s just five years old. However, it’s owned by 27-year-old Grepow, a leading battery technology company with four factories, 300 engineers, and over 3000 employees. Its products meet ISO 9001, ISO 14001, and IATF 16949 international quality standards, so it’s not a fly-by-night outfit.
I also had the chance to test the jump-starter function on a Honda Nighthawk 750 that had been sitting unused for 15 years with a completely dead battery. Despite the battery being unable to hold a charge, the JP400 delivered enough current to crank the starter. Delivering a claimed peak output of 2500 amps, it should easily start any motorcycle motor. Lokithor rates it as capable of jumping gasoline-powered engines as large as 8.5 liters in temperatures ranging from four degrees below zero to 140 degrees. Smart technology prevents sparking and polarity mistakes.
Jump starts are few and far between, so its secondary capability as an air compressor is a valuable benefit.
The Lokithor JP400 is slightly larger than most dedicated tire inflators, but comparable in size to other portable jump starters. It features an easily read display that provides information on battery charge, psi, and operating modes.
One design choice worth noting is the hose connection. Many inflators I’ve used in the past rely on screw-on chucks that thread onto the valve stem. While this creates a secure seal, it can be frustrating to use at awkward angles—particularly on motorcycle wheels with limited clearance. The JP400 instead uses a traditional clamp-style chuck, similar to those found on bicycle pumps. This makes it quick and easy to attach—simply push it onto the valve stem and clamp it securely in place. In some cases, wheel spokes may interfere with the clamping motion, but the same issue often applies to screw-on connectors as well.
To test performance, I compared the JP400 against my older Fanttik X8 tire inflator. Starting with a flat 100/90-18 front tire on my Triumph Bonneville T120, I inflated it to 40 psi using both devices. The Lokithor JP400 handles the job in 2 minutes and 15 seconds, which is 45 seconds quicker than the Fanttik XB.
That 25 percent advantage makes the JP400 noticeably faster. Neither device showed significant battery drain after the test, and they are capable of multiple refills on a single charge. The JP400 can pump up to 150 psi, making it suitable for use on bicycles, as well as trucks, automobiles, and sporting equipment. Simply enter the desired pressure and let it do its job.
This impressive performance, combined with its power bank and emergency LED flashlight functions, makes the JP400 a highly practical companion, particularly when traveling on older or less predictable motorcycles. At 1.7 pounds, it’s not ideal for short city rides, where it’s not essential. However, its 7.2-by-2.1-by-3.7-inch dimensions make it easily totable in a pannier or trunk—especially valuable for long or remote trips. Lokithor claims the battery is good for 36 months in standby mode. Lokithor offers an optional hard-shell travel case for $24.
The Lokithor JP400 is a great choice for compressing multiple emergency tools into one robust, user-friendly, and portable device. It provides peace of mind, combining jump start, tire inflation, flashlight, and charging capabilities—all vital for older bikes or remote outings. The MSRP is $100, though at the time of this writing, it is available for $70 from the Lokithor store on Amazon.
