POWERFUL BUT COMPACT: With 800 amps peak current, the Tacklife T8 can jump start 12V cars, SUVs, trucks or vans up to 30 times on a full charge (charging takes 4.5 hours). It’s a compact power bank (18000mAh capacity), can charge your phone with dual USB ports (one is a 5v/9v Quick Charge) and power your other car accessories using a 12V 10A DC port.
LONG-LASTING STANDBY TIME: Unlike other car jump starters, you can manually turn the Tacklife T8 ‘OFF’ to slow down the battery's self-discharge – allowing to the T8 to hold its charge for up to 12 months while not in use. (Please remember to turn ‘ON’ before charging or it will not charge.)more
