Notes
This GoDex Power Case was touted as having extremely high mAh capacity, but it tested at only 16.7% of it’s advertised capacity. It’s relatively low Specific Energy and Energy Density is mostly due to a plastic case containing the cell pouches, charge circuitry and an LED light source and switch. It’s three 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 is relatively large and low energy storage density for powering small loads like a ham rig.
