The M81 GX400multi-function intelligent jump starter is the perfect companion for petrolheads, boaties, bikers, off-roaders, outdoor adventurers, campers, and anyone else who needs to crank an internal combustion engine to keep or get moving.Boasting a high-power delivery potential rivaling and exceeding most conventional lead-acid batteries, the M81 GX400 can start just about anything running on a 12V system - car, bike, boat, you name it. Capable of a peak of 4000A, and a sustained 850A for cranking, the tiny jump starter packs some serious punch. The M81 GX400 also provides the added convenience of being able to double as a work, safety and emergency light, as well as a power bank for all of your portable devices including phones and tablets. The GX400 also has the added feature of fully supported 10W wireless charging.Its ruggedised case provides excellent shock and knock protection, and its IP65 rating allows it to serve in a wide range of environmental conditions, whether you are off the beaten track, outside the heads or anywhere else you might need to take it with you for peace of mind.Polarity and Overload ProtectionFeaturing sophisticated circuitry capable of voltage sensing and able to detect a range of fault conditions, the intelligent jumper leads included with the GX400 take the risk and unwanted drama out of emergency situations. One can be forgiven for connecting leads backwards in a stressful situation, and traditional jump starters would happily let you fry your vehicles electronics in such an event, but the GX400 will not allow a discharge when reverse polarity is detected.Equally important is the spark arresting technology, preventing potentially dangerous sparks occurring if the clamps accidentally touch together whilst reaching into the engine bay.Charges USB devicesUSB connectivity can mean a lot of things - first and foremost, the need for yet another

When I received the M81 GX400 I was impressed by the build quality and it arrived 100% charged. It appears intuitive to use although I have not had to use it yet. It gives me peace of mind knowing that should there be a battery issue, I won't be left stranded.

Life Saver. We are using this to jump start a fork lift in our warehouse. Its getting used once a week. Its a rock star and does the job every time. SOOOOOO Much easier than having to run jumper leads from another car. Plus you can charge your phone on it.

Very disappointed. I recently had a flat battery in my six cylinder diesel but felt secure in the knowledge that I had this jump starter….. that was until it failed to even turn the engine over. After several attempts I pulled out my 1500 amp I Tech which cranked it over without any problems. This thing is a dud!

Hi There We are sorry to hear that you are having issues with your M81-GX400, can we just check that you have charged the jump starter for overnight even if the display states 100% before using? This is because they only come with a float charge and they can be on the shelf for anywhere between 6-8months. If you still have issues with the Jump starter we will be happy to exchange or refund the product. Regards Automotive Superstore.
