Answer:
In the GB70 I recently purchased, it came with a paper manual, drawstring bag, the battery with attached jumper cables, XGC cable, 12V male and female plugs (cigarette lighter adaptors) and USB type A to micro cable. It can be charged or provide power via either cable.

Answer:
One way to look at your question is in Watts (W) Your question is about operating a device that draws 2.5 Amps (A) for seven hours. The Watts used would be (A*Volts)*Hrs or (2.5*12= 30 W)*7=210 W. The NOCO GB 20 is a 400A 12V unit so it's W storage is 400*12=4,800 W.

In general you should not discharge Lithium batteries below 20% so you would have 3,840 usable Watts for operating your device. 3,840/30=128 indicates that you might expect 128 hours of operation from a GB20. see less One way to look at your question is in Watts (W) Your question is about operating a device that draws 2.5 Amps (A) for seven hours.

No it will not. As long as there is a vehicle battery still in the vehicle the vehicle battery acts like a filter, though the boost pack should not be used as a stand alone battery using the clamps.

Short answer: Yes, you can charge the GB70 using the 12V cigarette lighter without running your engine.

I know this is an old thread, but I found the question interesting. The Noco GB70 has a lithium ion battery with a capacity of 56 watt hours (Wh); equivalent to 56 watts for 1 hour. A typical car/starter battery is equivalent to 45 amp hours (Ah); even though they are not normally rated this way. A recommended Depth of Discharge (D.O.D.) for a car/starter battery is 20%. This is equal to (9 Ah x 12 volts) = 108 watt hours. This is the amount that you can safely discharge without hurting your car battery. Basically the unit's 56 watt hours is less than the 108 watt hours that you can safely discharge from you battery, so you're OK.

Keep in mind that if you were to discharge your car battery to a 50% D.O.D. (not recommended); your car may not start. Basically a 50% D.O.D. would be (22.5 Ah x 12 volts) = 270 watt hours. For example say you were using an inverter to charge a 400 watt hour ebike battery, you would definitely kill your car battery.

I would say that you would be safe to charge most power banks, since they are usually less than 100 watt hours (TSA limit). For example the larger power banks like 26,800 mAh are equal to (26.8 amp hours x 3.6 volts) = 96.48 watt hours. However I would suggest that you drive your car soon after, in order to let the alternator charge the 12V battery back up. Hope this is helpful. see less
