NOCO Boost GB70: 2000A UltraSafe Jump Starter – 12V Lithium Battery Booster Pack, Portable Jump Box, Power Bank & Jumper Cables - for 8.0L Gas and 6.0L Diesel Engines

Q: what comes in the GB70 package?

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.

Q: What are the cranking ams and peak ams?

The NOCO Genius Boost HD GB70 2000 Amp 12V UltraSafe Lithium Jump Starter is rated in joules. Calculating in joules as a measurement of power multiplied by time, demonstrates the actual starting power as opposed to the peak amp measurement over an indefinite amount of time. It has a peak current rating of 2000 Amps and is rated at 15700 joules. As a reference a traditional 1700 peak amp lead acid battery jump pack has 6950 joules. Let us know if you have any other questions.

Q: If I wanted to power a 12 volt appliance for 7 hrs. that draws 2.5 amps, would any of these units be capable of doing that? If so which one?

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.

Q: Is this okay to leave in the car in the winter?

Yes, periodically charge the unit though, like every 4 or 6 weeks.
