FLYLINKTECH Portable Automotive Jump Starter, 1500A 12V Lithium Car Battery Booster Jump Starter Pack Emergency Light w/ USB 3.0 Output / Type-C Input，for Up to 8.0L Gas & 6.0L Diesel Engines(Red)

That's the size of this battery back up in it's case, with the connectors. I have a big, fat cruiser motorcycle that stays on the battery tender, when I'm not riding. I was always cautious of the battery charge level, every time I would go riding. I would wonder how many times I could start the bike, on a long ride, before I started having battery problems. Not any more. This emergency jump starter has put an end to my worries. To test it, I pulled the clamps off the battery posts and connected them directly to this jump starter. My bike started just fine. And, I'm talking a big, heavy 2000 cc V Twin. Not some little 750cc scrambler. The whole jump starter package is about the size of a cigar box, and very light weight. The battery clamps are detachable, with an LED in the attachment to indicate that they are plugged in properly and working. The power pack has a set of LED's to indicate the charge level. It's an 'intelligent' LiPo battery that will maintain it's charge for a long time before you have to cycle it. It's also safe to transport in your trunk (or saddle bag). So, yeah, I'm happy. Five stars.

With this virus going around, not driving and when I do, the battery is dead. My old yellow jumper died, so I found this one with good reviews. My battery is huge on my Dodge Challenger and it needs the big power type of jumper, and this one with 1500 amps works great and starts my car up fast. One charge is equal to four jumps and then charging over night, right back to full charge and stays charged too. The only thing that caught me by surprise is that after 30 seconds, jump turns off, a safety feature where I hit the timer bypass button on the back of the plug, and jumper plug goes to green light and cars starts on the first try like no battery issue at all. Has good built in lights and can even charge the phone fast too. No cons, can't think of a single one, where I am very happy with the purchase.

The charge comes with a charger, so no need to please another driver to help you to charge your car. I'm a mechanic, and I fix cars for other people. Use a couple of times to find this work pretty useful. However, the item does have some disadvantages. We found that one full charge battery can only charge 3-5 cars, depending on the car battery. Also, it could take 8 hours to charge this battery, and this is another thing that this product can improve. However, for the price here compared with the brand name, it's great.As for daily users, this is probably a good tool to have in your car because you never know when your car battery will quit. The charger is light and small, it can fit in your car drawer or back of your car next to the medical box.

I absolutely love this product for a number of reasons. I purchased it mainly because my mother in laws car battery kept dying and she struggled with our very large battery booster. It has exceeded my expectations. It has a perfect carrying case, and acts as a battery pack and/or booster. Keep it in your car and never worry about running out of a power source - it takes up next to no space at all. It clearly displays the battery percentage on the screen making it really easy to tell if it requires charging. It supports USB, has a flashlight and strobe light. I think everyone should have one of these in their vehicles. Definitely recommend.

I bought this battery charger because I live in the hot climate of Arizona and our batteries die quite frequently especially in the summertime. This charger is so compact and comes with a very nice case and you can also use the charger to charge up your phones and all kinds of other electronic devices real simply. I like that it has the different flashlights for emergency when you're out on the road especially at night time and it's super easy to charge. I haven't used it on my car yet, but I'm sure it'll do a fantastic job.

This product is really good and can help you when you need it the most. Because of COVID-19, my car has not been driven for several weeks and the battery is dead. This spare battery really solves this problem. In addition, I found it You can also charge your mobile phone, this is a must for travel and home!

It's a great jump starter. The most liked about this thing is you can use two type of charger to charge it. And there is two very big light if you ever needed to jump start or fix your car in night time. Another thing about this is that you can use it for diesel truck as well, which is the main reason i bought this, as i was looking for the one which can be used in small car and truck as well. Loved it so far.

Love this product!! I have neighbors that are out of state for months at a time. After a few months I tried to start their vehicle. No go. Have to admit it did take four trays to get it started but, it did the job! I carry jumper cables in my car but this is soooo much easier to use.
