To fully charge your CEN Tech 4 in 1 Portable Power Pack, the initial AC charging time can take up to 48 hours. Subsequent recharges typically require up to 30 hours. To charge the power pack, connect the 120VAC adapter to a standard 2 or 3-prong outlet and then plug it into the 120VAC charging input on the back of the jump pack. The charging indicator lights will cycle through red, yellow, and green during charging. Once the unit is fully charged, the green light will remain illuminated. Regularly monitor the level while charging, and remember to unplug the jump pack when it is completely charged to maintain its performance and warranty.
