Notes
(Unit had to be modified to disable it’s emergency crank start protection. Without this mod the 12 V output would only enable for 20 seconds.)
This QuickCable PowerPack was advertised as a 20,000 mAh battery, but it tested at only 11.7% of it’s advertised capacity. It’s relatively low Specific Energy and Energy Density is mostly due to a large plastic case containing the cell pouches, charge circuitry and an LED light source and switches. It’s four LiFePO4 pouch cells allow it to deliver very high currents for a short period of time, since it’s advertised use is as a vehicle jump-start battery. For this purpose it is supplied with a set of car battery clamps. It has a high-current relay which only enables the 12 V output for 20 seconds to protect th battery from over discharging. It’s inability to output a maintained 12 V makes it unusable for a ham power source.
