Jumpbooster 12 Volt 4000 Amp  JP30 heavy duty jump start for Trucks

 The 12V JUMPBOOSTER MGC4012 Delivers New Standard for Battery Safety, 

 Performance and Reliability for the Trucking Industry

 Marxgold is the Australian distributor of a ground-breaking new jump starter battery designed specifically to jump start heavy duty diesel trucks instantly. The 12V JUMPBOOSTER MGC4012 delivers a new industry standard for safety, performance and reliability to over-the-road truck operators.

 Dead batteries are a huge issue in the trucking industry, causing expense, delays and lost opportunities. But now, thanks to the revolutionary new JUMPBOOSTER MGC4012 from Marxgold, those worries are a thing of the past.

 "The JUMPBOOSTER MGC4012 is the most powerful, smallest, lightest and best value lithium-ion jump starter on the market that can INSTANTLY jump start your heavy-duty diesel equipment up to 16L," says Mark Bygrave, Director of Marxgold Starting Solutions. The unit is so powerful, weighing only 5.6 kgs, it can even start a heavy-duty diesel truck with no lead acid batteries connected.

 The compact jump-starter device produces a full 4,000 peak cranking amps, more than enough to start any diesel truck engine up to 16 liters in displacement. Safe, efficient and easy to use, the JUMPBOOSTER MGC4012 truly is a game changer for over-the-road truck drivers.

 Instead of having to roll out an unwieldy 160kg lead-acid battery cart to start a dead battery in a big rig — often in inclement weather — the JUMPBOOSTER MGC4012 weighs 5.6 kilograms. The JUMPBOOSTER MGC4012 unit performs and exceeds past what's advertised in a compact, easy-to-use package. It offers increased safety because it's so easy to use. It does give a 'wow' factor for our customers.

 "I don't know of any shop anywhere that would want to be without one of these if their business is repairing trucks,"  "There is no other product out there like the JUMPBOOSTER MGC4012."

 The secret is JUMPBOOSTER MGC4012 high-output lithium-ion batteries, which use microchip technology to keep from ever overheating, while at the same time delivering the massive power truckers need. Just connect the JUMPBOOSTER MGC4012 to their truck's battery terminals, fire it up and drive away.

 The power of the JUMPBOOSTER MGC4012 is available in both 12 volt or 24 volt. 

 On top of the ample cranking power, the JUMPBOOSTER MGC4012 comes with a host of versatile and practical features, including two cigarette-lighter ports, two USB ports, an extra-bright LED flashlight and built-in smart cables. When it isn't being used for firing up an engine, the JUMPBOOSTER MGC4012 can be used to recharge a laptop, phone or tablet, and other electronic devices.

 The JUMPBOOSTER MGC4012 has a seven-year lifespan and provides instantaneous power on demand. Over its lifetime, it can provide up to 5,000 starts. Safety features include reverse polarity, low-voltage protection, short circuit overheat protection and over-discharge protection.

The jump starter is offered with features such as reverse polarity, low-voltage protection, short circuit overheat protection and over-discharge protection and delivers up to 5,000 starts.

 While demonstrating to customers i have been able to start dead flat Freightliners, Kenworth's and Mack's. Due to the nature of calling in on businesses, there is always a dead truck that hasn't been started for a long period. These are trucks that isolators have been left on and parked for extended periods. NO Glow or click and batteries showing < 2 volts. without the JUMPBOOSTER MGC4012 connected. Quite often a couple of 5+ seconds sets of cranking before the engine starts. A start like this will only take around 5 to 8% our of the JUMPBOOSTER MGC4012 battery. Once they have been started, a second starts instantly and will use 1% or less to start.

 A high quality lithium powerful jump starter for the trucking industry. Built heavy duty and capable of starting 16 liter diesel engines.

    Cannot comment as I haven’t used it yet. I was introduced by a friend he has the bigger 12/24v unit and I was very impressed, but I don’t need the 24v option

    I have one of these jump starters. I have owned different types over the years but this is way superior. I have owned it for 9 months and so far is has handled all I have asked of it. From 370hp tractors to 10hp stationary motors. My fear it&#039;s longevity but to date I am very impressed, it is a big price to purchase but providing it remains problem free I will consider it money well spent
