Nice Compact Jump Pack

This review text is styled with strikethrough formatting

I purchased this NOCO jump pack through Walmart because of overnight, free shipping. Still ended up taking 2 days to deliver but this is a great compact jump pack. Small enough to carry in my glove compartment so I know it's always with me. Comes with a charging cable but both ends are C USB so I need to find an adapter to be able to charge it through my truck. Easy to plug jump cables into and seems strong. I used it a couple times already and had to recharge it once since then. I hope I get many years and jump starts from this unit. Comes with a cloth carry bag with a draw string that doesn't seem too sturdy. I may find a hard case to store it in for future.

About this review:Walmart fulfilled this order and the fulfillment issues were not the fault of the seller.

Too early to tell. It's being charged as I type. All I can say is it is sturdy. It's solid, the clamps are strong and heavy. If it is as good as it looks. It will be a dandy. Kinda crazy buying something that you hope you never need. If I ever do though I'm ready. I will give a update if I use it.

Worth every penny- packed away my jumper cables!!

This jump starter is truly a game changer and my only regret is that I didn't get one sooner. It's top notch as far as build quality/materials, it functions flawlessly (the haters probably need to read the directions and watch the instructional videos online), recharges quickly using a fast charge wall adapter, and is unbeatable for convenience. It'll make you want to ditch those old jumper cables when you see what this small powerhouse can do- just you wait and see. It comes with a fabric bag to store and carry the device, which is fine, but after falling in love with this thing I purchased the optional manufacturer-made rigid carry case for it. Doing that just rounded out what I would consider to be one of the best purchases I have ever made as far as automotive accessories. Highly recommended!
