HPMJ is a heavy-duty jump starter that is built in a compact size, for easy storage and handy to use when in need. Most battery manufactured uses generic low current rating enclosure that can cause damage or even explosion of the battery when jump-starting a car. HPMJ’s battery is able to produce a higher current compared to similar products in the market while reliably and safely starting cars .
Customers are also able to opt for patented reverse polarity protection clamps making the process easier and safer for all. HPMJ’s reverse polarity protection clamp allows drivers to avoid snapping on the wrong polarity; when they do however, the mechanism behind the product will emit beeping sounds to inform the driver.
