The one I have is pretty much as you describe on the inside. I think mine (Harbor Freight
model), is a 24AH gel cell inside plus charging electronics. Mine lacks the LEDs but does
have a big on/off switch that disconnects power from the cables.
Never used mine for jump starting, but do use it to run my camping fridge while camping
(will power that for about 24 hours) and for inflating my air mattress for camping.
X2 on those solar trickle chargers, I have one on the dash in the VW, seems to do a decent
job of keeping the battery up when it is not run for a while.
