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.

Noco 45

With great reviews, it was an easy buy. It was not available at my local Walmart So I went on walmart.com and ordered it. It was here in three days. I tried it out by using it to jumpstart the generator. Worked great.
