final word on the subject from me. Jump starters are o.k. for powering
small mounts such as EQ2 or 3, but are pretty useless for powering
medium to large mounts such as HEQ5 or NEQ6 or larger. An HEQ5 used
for viewing involving a lot of slewing can flatten a fully charged 900amp
jump starter in a couple of hours, as it has typically only around
7amp/hr capacity. You can get a bit more amp/hourage with a heavier duty
jump starter, but what is the point when for just a few dollars more you can get a small car battery that will power your rig for about 5 or 6 times as long.
