Size: 12V-3000A
I bought several of these, one for each family member. Used for “jumping” a dead battery or to power smart phone during power outages. Seems to hold charge for 6 months (at least). Best thing about these is if you are helping out another person in a parking lot, etc., you don’t have to use your car or pull out your jumper cables. This is safer and much more convenient. This model was highly rated by a YouTuber and I waited until they went “on sale” and got a very good price.

Purchased this primarily because I've began working on vehicles before 1990 a lot more than usual. And of course the issue older vehicles have are dead batteries. I used this boost pack the other day as my primary boost pack went dead after jump starting 4 other vehicles. After connecting and starting the first vehicle ( 1980 trans am with the 4.9l) the starter sounding like it hadn't received that much voltage in years! Fired up within 2 minutes of cranking! Curiosity got the best of me and I wanted to see how many I could start before it needed to be recharged..... I successfully started 9 dead vehicles with this thing.... Holy crap my big bost box struggled after 4 dead starts and I just recently installed a lithium reserve battery in it. Definitely my primary boost box now hands down.

I don't normally take the time to leave reviews, but I just used this thing to jump start a 13-liter six-cylinder diesel engine three times as the cranking batteries are shot. It started it right up each time and it is still 75% charged! Short term it has been awesome. Long term is still yet to be determined.

Great value! I have jumped cars, trucks and even diesel generators with no issue. It lasts a long time between charges as well. I have used this pack for nearly 3 years prior to writing this review and it's still going strong!

Jump started my semi truck twice and only went down to 75% kicked in even stronger than the original crank. A realy good purchase that solved a big worry. It's so easy to do that my dog can handle it.
