VTOMAN 2500A Car Jump Starter, Portable Battery Booster for 12V Vehicles (6.0L Gas/4.0L Diesel), 10000mAh Fast Charging & Jumper Cables, V6 Plus

ok im not sure about the battery use or even ppwer level just yet. i finally had thw opportunity to use thus this afternoon. ive been having issues with my battery and no money for a new one yet. i also didnt want to drag out the extension cord and charger/booster ro jump the van. so i was a little skeptical about this because I boughr one once before ans it even had an air pump on it. ans it would not jump the battery in the can. i plug this up with the adaptor and clamp it onto the battery. Turnds thw key and started right up. now im notnsurw how how many uses before changing. i do like the fact it has a lithium ion battery in it. i have an impact with a lithium battery in it and i charged it once in 2 years and its been sittin in the back of the can ans has not died yet. so ill be lea ingnthis in the van for when i need it. highly recommended so far for boosting your battery. now if the batteey has been dead for several weeks to a month im not quite sure it'd jump it.

The VTOMAN Car Jump Starter is a welcome device to have in my vehicle. Its compact size makes it very easy to store when not in use. The device comes in a carrying case which holds all the components. In addition to being able to start your vehicle with a low or dead battery, it offers other handy features such as a flashlight with several settings (such as strobe white, strobe red and SOS). The device can also be used to charge your electronics. The quick reference guide offers step by step instructions (with diagrams) on how to start a 12V vehicle. I have no vehicle with a dead battery at this time so I have not been able to actually use the device to start a vehicle. The charging function for electronics, however, works well. I am happy to know that should I need a boost due to a dead battery, I have what I need to get my vehicle going again!

This works great. we've tried it on a car and golf cart and it worked perfectly. it is small and compact so easy transport with you. Comes with the charging cord and a nice case. only downside no instructions. they are digital so you have to scan a barcode. other than that its great with a very affordable price.

This is a very promising jump starter and is quite compact. It does a great job starting a vehicle and is very convenient due to It's small size. You can actually use it as a power bank as well due to the USB output connection. This is a no frills version without a gauge but performed just fine. The usage is straight forward and it comes with a nice pouch as well to keep it safe. Absolutely nice to have around for emergencies.

Ready for any event, Have a power charge to restart my car battery %26 a power source to charge my devices in case of emergency or natural disaster, This is a MUST HAVE for anyone

works as described. my car dies all the time so this will be nice to have on my car and give me peace of mind.

Great product! Worked right away! Great price. Definitely recommend and would buy again

Don't need to wait hours for a tow truck anymore, this device is a portable game changer

Arrived today. Already a charge to it, but I charged it a little more to test it properly. I drive a 2008 Mini Cooper so my battery might be a smaller type. It jumped it on two after I let it sit a while. My battery in the car is new, but really low charge from sitting for months (car was having coolant issues) if that gives you any reference to how these smaller portable jump packs work. I have a larger one too, but it is old and those types are expensive. This is just one test. I can not review for the durability of the product as I have not owned it or used more than once. I do wish these had a indicator light for how full the battery life was during use. My other one uses a 3 dot system to show during charging and during use. The plastic on the clamps are cheap too. I wish they had used a vehicle type plastic and not that cheap hard plastic that cracks easily under extreme temps. If you want something easy to store this is it, but if you want something you will use all of the time (farm, mechanic, large equipment) I would get something bigger and better. These are designed for just in case jumps not for something to use 10 times a day. I will be giving this one to my friend's daughter who does not know anything about cars so she doesn't have to worry about dead or low battery life during winter conditions. Recommend.
