The Noco GB40 contains a 1200 mAh battery, which is a 24 Watt Hour battery.
Amps x volts = Watts, so 24 Watt Hours divided by 12 volts means you can draw 2 amps for an hour before running the Lithium-Ion dead. Or 1 amp for 2 hours.

There are other L-ion battery packs that are much, much better for use as a power source than the Noco. I think of the 10 units that Consumer Reports tested, the Noco (BG30 - 400 amp model) came in second to last when it comes to being a charging source for laptops, cell phones and other devices.

Top five ranked L-ion jump packs from Consumer Reports are
Antigravity Batteries XP-10 (18000 mAh battery, tho, so there ya go)
Spirit A8 Car Jump Starter
Bolt Power D28
New Brights Compact 12000mAH Mini Portable Car Jump Starter
PowerAll PBJS12000R.

These units provided strong jump-starting performance, along with good accessory charging options.
 

 

Noco GB40... non merci... pas assez de JUS pour le usb à mon gout

je veux un jump starter polyvalent

I am very disappointed with this 69800mAh Car Jump Starter 12 V Portable Power Bank. Don't waste your money with this one. My thoughts, other Car Jump Starter Power Banks are probably grossly over power rated, just like this one.

* All tests were done with a full charge of 5 bars and 16.64 volts.

The battery inside:
- The full charge voltage is 16.66 volts.
- After three charge / discharge cycles, my power meter rates the battery as a 23.76 watt hours, 1600mAh (low power) battery made up of four Lithium Ion cells.
- The actual current draw was 60 Amps for just a few seconds. The battery quickly dies off with that load (a few seconds).
- The manual claims 300 starting amps and 600 peak amps (that is complete BS!).

- The blue and red flashing LED's looks really cool.
- The plastic case will hold the unit and all accessory cables.
- The USB ports will only partly charge your tablet or phone. It only has a 1600mAh battery inside. (Big fail). Very disappointing.
- To conserve the battery, the unit auto shuts down if no load is connected. That's great!
- Selecting the 15 volt output with a 250 mA load, my voltmeter reads 16.4 volts (fail).
- Selecting the 16 volt output with a 250 mA load,my voltmeter reads 16.4 volts (pass).
- Selecting the 19 volt output with a 250 mA load, my voltmeter reads 19.12 volts (pass).
- The four USB ports can deliver 5.05, 5.08, 5.05 and 5.05 volts at 1 amp and 4.93, 4.95, 4.94 and 4.93 volts at 2 amps.

- The unit only has a 1600mAh battery (no, I didn't forget a zero) (very big fail).
