1500A Peak Car Jump Starter, Oittm 15600mAh Car Battery Booster(Up to 8.0L Gas and 6.5L Diesel Engine) Power Bank Portable Charger w/USB Charger+Quick Charge 3.0+Type-C+12V DC Output+LED Light

Alright. So I have a STANLEY PPRH5 which I had bought for a camping trip a few months back.It has a sealed lead-acid battery in it (think tiny car battery.)It could jumpstart my mom's 4 cylinder Chevy Cruze, my 4 cylinder Nissan Altima, and anything else. Even at full charge, it has problem jumping my 2006 6 cylinder Ford Explorer.So, my Explorer's battery is dead, won't charge at all, and the thing just sits in a parking space, rarely driven.To jump it with my STANLEY PPRH5, I have to let the jumper sit connected to the battery for about ten minutes before it has enough power to start the engine.With this little beast here, the Oittm Jump Starter, at 3/4 of its full battery life, I connected the cables to the battery in the vehicle first, then to the battery bank, and then held the button on the cables until I heard the relay click.After that, I turned the key in the vehicle, and the engine came to life.I was immensely surprised, I really didn't think it would work, being lithium-ion, but it did, and did it perfectly.I HIGHLY recommend this to anyone and seeing as to how easily it started my 6 cylinder Explorer, I bet it can handle almost anything.

 I don't often say this, but I wish it was possible to give more than 5 stars on this product. I was very skeptical about this Oittm jump starter due to the small size but I couldn't have been more wrong. This thing packs a punch!Everything comes packaged neatly in a really nice, soft/rigid, zippered carrying case. Inside the foam-lined case is the charger, a set of jumper cable clamps, a usb wall charger, a usb type-c cable and an instruction manual. The manual is a little confusing in one respect, but I'll explain that in a little bit. The carrying case is really nice for keeping everything together.The charger itself looks and feels really sturdy and well-built. It has 4 blue lights on the top close to the power button that show its charge status. A full charge is 4 blue lights and one light indicates it has 25% remaining. At this low charge state it won't jump start your vehicle but it will still charge through usb (like your cell phone). The front of the charger features 2 usb chaging ports, a flashlight (that's pretty bright) and the jump starting port. I was able to charge my Samsung Note 8 with no issues. I was a little bummed that it wouldn't "fast charge" as the ad suggested, but I've had trouble with my phone fast charging on other chargers so I can't say for a fact that it's a deficiency in this pack. It charges my phone and the minor inconvenience is not enough to affect the score at all. There's also a 12 volt DC port on the side of the unit that can presumably be used with a dc power cable to power a 12 volt device. It doesn't come with that type of cable and the directions don't go into any detail on what it can be used for, so I can only speculate.When using the jump starting feature, the jumper cables have a gray plug attached to one end. The directions tell you to insert the gray plug into the jump starting port and then power on the unit, but what they don't tell you is that the power button they're referring to is actually ON the gray plug itself, not on the actual power pack. I found this a little confusing at first and kept trying to turn it on with the little red power button on the top, but that wasn't it (that turns on the charger and the flashlight...long press that button for flashlight).To test this thing out and make sure it works, I actually disconnected the battery on my Ford F-150. I wanted to make sure it could cut it before I could depend on it to get me out of a pickle. In a normal situation you would connect the jumper cables to the appropriate positive and negative posts of your car battery but I actually connected them directly to the wires on my truck (well, I shared the ground). When you connect the cables properly, a little light on the gray plug flashes red and green quickly. When you're ready to start, you press the little gray button (shown in the pictures and my video). At that point, the charger makes a clicking sound and the light stops flashing and turns solid green. It's now putting out 12 volts to the cables so make sure you don't press the button if the cables are touching each other. When the light is solid green it'll stay on for 30 seconds and then shut off. This is a safety feature and completely normal. Once the light was solid green I went and turned my key and to my surprise it started right up! I couldn't even tell that it wasn't my normal battery. It turned over easily and had plenty of cranking amps to start it right up. I was very impressed. That's a lot of power packed into that little package. After starting my truck, the power indicator lights went down to 3 lights (75% power remaining). I was very impressed.I included the video of me starting my truck along with this review. (Although it might look like I still have the cables connected to the battery, I actually have a rubber cap over the + terminal and the cables are just resting on top of the cap.) I would definitely recommend this jump starter to anyone looking. I'm probably going to get a second one to keep in my wife's car for emergencies. It would also be great out on the boat. This thing is very impressive especially compared to some of the big clunky options out there that I was looking at prior to this one. In my opinion, this Oittm Jump Starter is worth every penny!

I bought another one of these as the last one I bought was given to family member since their car died recently at airport.While I have not used this one yet, I really like it better than my last one. Case is hard, so it protects it all, cables are longer so will be easier to use when needed, came fully charged and comes with a charger as well. Last one I bought didnt.Time will tell how this works when needed (will update if have to lower rating), but I did read instructions. It lets you know you wont be able to use if battery is only at 25%, so I'll make sure to recharge this thing every few months so dont have to worry if its good or not when needed.While this one is bigger than the last one (physical size), I got plenty of room under my car seats in truck for storage, so fits my needs. So if you're tight on space, this might not work for you, or you just dont use the case.

This thing saved me twice in one week (I had a bad alternator and was still diagnosing). It actually took a couple of tries each time for my minivan, but it got me started (worked better when attaching to the base of the terminal where the cable meets it rather than the part that slips over the battery post).Compact and comes in a really nice case.I will say they could do a better job of making it clear that for jump starting you must press the small grey button on the plug for the cables as that would be easy to overlook and had I not researched this product well in advance, I wouldn't have known. The big button for the flashlight is much more intuitive to press but at least they made it so that the unit must be flipped over in order to see the jump start led indicator light, so that helps.As for charging? I have a weekly reminder set in my calendar and simply plug it in my car outlet while driving around until it's topped off. I highly suggest you do something similar to make sure it's ready when you need it.

I was looking forward to get this product for a while.This is a heavy duty battery that can jumpstart my car if the battery dies.I have AAA Service, but they usually take at least an hour to show up. And getting someone to give you a jump is not easy anymore.And also serves as a backup charger for my iPhone, iPad and MacBook.The flashlight feature is a plus. Being a LED flashlight, it should last forever; great to have during hurricane season or while camping.(I have previously purchased a Solar Panel to keep this and my other batteries charged when there's no AC power around.
