YESPER Jump Starter Portable,1500A Peak Motorcycle Jump Starter, Jump Box for Car Jumper Starter Portable, 12V Auto Booster Pack(Up to 7L Gas and 5.5L Diesel Engine) with Smart Safety Jumper Cable

Its a greatly designed product, I havent tried it out with my car yet (cause i jumped it with my friend's car instead before it arrived) but I trust it'll work when I need it to, it's a great thing to have for peace of mind on trips and just makes sense to have for daily.The size is actually partly why I bought it, cause usually these battery jumpers will only be needed in that specific instance that you need it (depends on how old and fussy your car is, but you get the point) so its good that this doubles as just another backup powerbank. The dimensions isn't much bigger than my old 10500mAh powerbank, almost the same thickness, just slightly wider and not too much taller which is understandable because remember IT CAN JUMP START YOUR CAR (and its 12000mAh). Just a no brainer to have in your daypack for emergencies, unlike other bigger car jumpers that, just admit it, you'll forget in the car (which, quick tip, don't do that, batteries and extreme temperatures dont go well together) and ends up being 0% when you need it. This one you can actually bring around for other emergency power needs. (Its a pretty good torch too).If I were to nitpick, or incase Yesper reads these, it would actually be a big brain move if it is updated to have the usb-c port as in/out and quick charge so it works even better as an emergency device powerbank that has a bonus function in JUMPSTARTING CARS. The size/dimensions of the fevice and battery capacity is already perfect. My phone is only 5000mAh so its more than enough and its a bad habit to charge your phone with powerbanks anyways, its only for emergencies when you can't find a plug anywhere or needs to get moving. And if you have a car hey good news you can turn it on with this then just charge with your car!

Do NOT underestimate this little guy. I originally purchased this with my motorcycles in mind, mainly because it takes up very little space, and jump starting a motorcycle doesnt require a lot of power. Then I found myself in the unexpected position of needing to start our jeep when the battery went south. I had a good jump pack handy, but thought "why not?" and decided to try this out. From not having enough juice to click when the key was turned, this little monster barely blinked when I hooked it up, and the jeep fired right up. Just to be sure, I shut it off immediately, and checked the battery voltage. It wasn't much above 10 volts, certainly not able to turn over. Hooked the vesper back up, and sure enough it it only took one key turn and it was running again. I haven't tried it on my big v8 yet, but I think it just might do it! Always one to be prepared, I keep jumping packs in all our vehicles, but I've already ordered a second Armor Mini just to carry in my backpack because you never know. Definitely recommend this, and frankly, can't understand why anyone would give it less than 5 stars!

Edit: used the jump starter on a dead 4 wheeler. Got me down the trail. This thing is legitI have yet to actually test the jump start feature, but am still going to give this five stars… here’s why.It works great as a phone charger / battery pack.Assuming it works as advertised for jump starts:This is the smallest jump starter I have found. Perfect for my 4 wheelers and snowmobiles. Especially the new stuff that is doing away with pull starts.One of the most important things I have found after owning many li-ion jump packs, is the boost / force button. This unit has that and is a must have. If the voltage on your battery is so low, some packs won’t even recognize they are connected to a battery. Making it useless unless you can force voltage from the jumper.It’s lightweight, small, seems fairly rugged. The battery leads are quite small, but fitting for the unit. The price was very fair compared to other jump packs. Even tho it’s smaller capacity, it’s exactly what I was looking for when it comes to size.

Easily to used effective strong durable. Safe to monitor last for about 4 hours a hile on duty be charging it also has functional bright light at the

This is such a perfect little jumpstart pack! I keep these inside my vehicle and also when I am out on the water on the jet ski. It has enough power to get your vehicle started. I love that. It also has an adapter where you can plug in a cell phone charger and a flashlight built-in. The battery seems to hold, I tend to bring it in twice a year to make sure it’s fully charged.

Worked as advertised, except that it needed a little more time than some of the reviews would lead you to believe -- about 10 minutes connected to the battery and my motorcycle fired up like the battery had never drained.

It's a dirty trick to put in a connector that LOOKS like the standard EC5 connector, but isn't. I have whips wired into all my vehicles so it's super easy to jump a dirt bike, or my van, if something gets left on or out of whack, but this darn thing doesn't connect. I found that out today, when I actually needed to use it and couldn't. Super pissed about it. I'd give 0 stars, if I could. If you only want to use it with the huge, bulky alligator clips that it comes with, maybe you're good, but I didn't and unlike every other jumper pack I've had, it won't connect with the whole ecosystem of accessories specifically for this type of thing. Check it out. Super pissed. Way too late to return it.

I was not expecting this tiny little power bank to have as much of an impact on my car. I bought it to have as an emergency just in case my battery died in my car. Welp sure enough the weekend I ordered it my battery died, no way to jump my car at 4am since everyone in my neighborhood is asleep. This little guy has more than enough juice to not only jump my car but charged my cellphone and jumped the car again all before needing to be recharged. It came fully charged also. Just plug in the jumper cables attach to your battery and hit that boost button seriously that easy.
