My old brick jump starter doesn't hold a charge very well any more. Anyone have experience with the new crop of lithium jump starters? I'm eyeballing a Weego Jump Starter Battery Pack+, Heavy Duty, 12000 mAh

I kinda like the compact size but worry a bit about carrying a potential fire hazard in my car everywhere I go.

I love tech but I'm still skeptical of these things. Why not just replace the SLA in your current jump pack? Cheapest option.

I've got one that looks extremely similar to the pictured one, used it over the last winter since I hadn't gotten around to finding the source of excessive dark current in my Miata, got me started for the weekly drive from the storage garage when it was nice enough out. Used it ten or so times, I think. I kept it inside at my house though, just took it with me when I drove to the garage.

That's a lot of money. I like the lead acid jump boxes. I paid $35 each for the two I got from HarborFreight, and they power my gear every day for work, and have power left over to jump start vehicles. I plug it in when I get back from work, and put the one I charged the previous day in the truck. If you don't *need* a compact battery, I wouldn't pay extra for it.

That seems an insane price when similar capacity Lion batteries go for maybe $30 on Amazon.

I have one of these.
Have you used it to start a car? Do you think it's reliable to get a well drained battery going? I like that form factor for my daughter. I also like that charge maintenance is more forgiving than lead acid(for her).

It's been used a couple of times to start a hybrid with a dead 12v battery - I haven't had the opportunity to try it on a bigger gasoline engine yet.

My mechanic says those things are awesome. I have a full size jump starter because I dont like to take chances.

Unfortunately it doesn't come with 2 little cables that plug into it so you can attach it to the battery.
I use my 18v battery from my cordless drill to jump start my car.

Whoa. I just clicked on the link, that's WAY more than I paid for mine.

Hm, looks like maybe I got lucky and got it at a promo price or something. But even on Amazon, comparable units are cheaper.

I picked up one of these a few months ago before a road trip.

The battery in my Subaru Outback was probably ~8 years old already, but working fine before the trip. The summer heat of Arizona and Utah started making me crank it for a few seconds longer every morning until one morning in Moab, the key fob no longer worked. The item above was able to jump my car maybe 3-4 times before I got back into town to replace the battery.

I thread a rope thru my crankshaft pulley and start mine like a lawnmower.

I've never had to jump start my vehicle but the air compressor has come in handy numerous times, including on my recent vacation out west, and the features like USB charger, 12V outlet, etc. are pretty neat. I received it as a gift a few years ago and can't say I would have purchased this exact model if I was spending my own hard earned money. I'd probably upsell myself to something even better.

I haven't had a lot of luck with cheap air compressors. They always burn out quickly. I keep a old hand pump in the truck. Not much fun pumping up a truck tire, but I can always count on it to work.

I have one for the bike and have used it twice. Thing keeps a charge for a long time too. Good investment if you want to save the space and weight.
