Customers say
Customers find the jump starter works perfectly, with one mentioning it performs well on ATVs and 4-wheelers, and another noting it can start an 8-cylinder engine. Moreover, the battery life is impressive, with one customer reporting 80% power remaining after use, and they appreciate its compact size and ease of use compared to jumper cables. The build quality is reliable, particularly for big engine vehicles, and customers consider it worth the price. However, the charge speed receives mixed feedback – while some say it charges devices quickly, others report it only charges to 71%.
