AchingBack I hear ya about jumping equipment. A while ago I wanted a small jump starter the old style was what had in mind and wasn't even considering the lithium packs yet they were pretty new then. So I think it was maybe thread too I was asking about the HF options. Their AMP pack wasn't high but I only needed it for small equipment really had no intention of jumping trucks or autos just mowers and motorcycles. So I also didn't want to spend a lot and even the cheapest HF was still $40 plus I would have had to mail order it too Our new HF store is barely 1 year old now.
So long story short I picked up this unit off AMAZON.
Amazon.com: Schumacher XP4 4 Peak Amp Instant Portable Power Source: Automotive
I have had for a couple of years now its so handy. I even use it for a power supply if need be, like test a starter whatever. I even tossed it in my motorcycle saddlebag one day when my battery was failing and need to be replaced Wouldn't hold a charge so I jumped it each time I had to start again
Just thought I pass it on
I have to say when I went looking for this the amount of the new style lithium packs to found on amazon now is amazing it took me awhile to locate this where it used to come quick
Obviously the other types could prove quite usefull too
