    Lots of power, good features
    This is a great unit. It has a lot of power and works well for multiple uses. I took it to my mechanic to test it on some dead batteries. This Schumacher unit worked well on the two dead batteries we tried. It was faster than my older, smaller jumper kits that usually need some time to charge the battery up before the motor will turn over. I pushed the “Jump Start” button on this Schumacher unit, and the motor immediately turned over. The cables are long, which is nice for when batteries are in inconvenient locations. The little flashlight on the end is not amazing, but it does provide some light. The USB charging port is close to a “fast” charge. I compared it to my regular fast charger for my phone and it only took about 15 to 20 minutes longer to get the same charge done. Support from Schumacher is great. The initial unit I received did not work. It would not turn on and the USB port was out of alignment with the case so that you could not access the port properly. I contacted Schumacher, per the instructions included with the unit. The support team was responsive and they have a well managed RMA program with an online portal to submit and track the return / repair. It made dealing with an issue less painful.

    Plenty of Power that Fits Beneath a Car Seat but has Awkward Charger Cord Storage Options
    Rated at 4000 peak amps, the DSR164 is one of the most powerful portable jump starters on the market. At any particular time, I may have to jump start a 6.4 liter V10 engine down to a single cylinder lawnmower. The DSR164 can handle them all. I like that the DSR164 has built-in Pre-Boost and Pre-Heating technology to help offset cold morning starts. Heck, it even has a bright LED light for nighttime emergencies that includes an SOS signal mode. There's also a USB output port for charging mobile devices. The DSR164 uses a pair of lithium-ion batteries mated to 4 ga, 30-inch cables. The cables are color-coated, and the jumper is internally protected against backwards connections. Overall, the DSR164 is small and light enough to be easily carried. The IP65 rated protection against moisture and quick splashes makes the DSR164 useful during a light snow or rain. I keep my DSR164 under my driver's seat, but it needs a better way to store the AC wall charger and 12V DC car charger. I threw them both into my glove compartment after I labeled them with a Sharpie. I hope I can remember where I put them. The clamps were adequate but might have worked better had they had been a little larger.

    Compact and Powerful
    The Schumacher Lithium-powered ProSeries Jump Starter is one of the best jump packs when you are looking for a reliable and easy-to-use tool that offers more functionality than to just re-power a dead car battery. This lithium battery jump pack is compact and rugged enough to keep in your car for roadside emergencies and can act as a portable power station to charge your electronics via a USB-A charging port. Additionally, there is a built-in LED flashlight with an emergency strobe. With 1000 cranking amps output, the Pro Jump Starter is compatible for use even with diesel engines. The heavy-duty alligator clamps are large and easy to attach to the battery terminals. The cabling is a larger gauge wire offering both faster charging and improved longevity. One of the best features of this jump pack is a convenient override function that's good for energizing a battery with a voltage too low for the jump starter to detect. Included is a 120v. wall charger, an in-car 12v. charger and a one-year guarantee should a manufacturing defect occur.

    OK but Can be Better
    The jump starter works once you figure out how to use it. That is because the instructions are not very good. It seems they decided instructions would be 4 pages and then stuffed something that should be 8 pages into 4 pages. It is difficult to figure out what the buttons mean as the photo is too small and useless and the buttons on the starter aren't labelled. It seems that instead of creating a version for each language, they decide to omit adding words labeling each button or symbol on the device. This made it easier to manufacture but more difficult to use. Another issue I had was that I tried to start a car with a dead battery, but the device didn't tell me it was dead. So, this jump starter while useful, could have been made a little more friendly to users such as adding a digital readout screen.

    Awesome Jump Starter
    I have been looking for a good jump box for a while and after trying several types over the years I have found one that is nearly perfect. This Schumacher powered DSR pro series jump starter is awesome! It has 4000a of power that can be used to jump a weak battery or even a completely dead one with the override button. If your battery is dead then just turn it on and then hold the middle button down for 5 seconds and it will jump a vehicle with a dead battery. It also has a very bright light on the side and can be charged with your cigarette lighter or a wall charger both of which are provided. The clamps on the box are very strong and small enough to get into tight places. Very satisfied with my product.

    Small Powerful Innovative Rugged
    Simple to use. Packed with features. Well packaged for safe shipping. Detailed ‘User Manual’ seems complicated but operating isn’t. This portable power station is small, durable, well made & designed- just the right length heavy duty cables and strong biting clamps for jump starting vehicle batteries. Charged to full with only a slight warming. Used to jump start riding mower battery that was nearly dead with ease. Reverse polarity safety is awesome. As is charge indicator light and boost to start button keeping clamps safe until connected. 3 mode light is bright- a long lasting flashlight. USB port great for charging devices, phones etc. This power station can be charged with either included charger- AC wall or 12V DC. Selected this Schumacher's jump starter to keep in my wife's car to ensure starting as the battery tends to drain after not being driven much and has not started several times. The ProSeries DSR164- Pre-heating & Pre-Boost add extra safety jump starting dead and or extremely cold batteries, making it perfect for having in any vehicle. Expect this to be another reliable super performing Schumacher product we can count on.

    You won't need those jumper cables anymore!
    I have a smaller automotive batter jumper that is much smaller. It has done a good job over the years with some cars, most motorcycles and riding mowers. It had similar features, but seriously lacked power for when I needed it most. A stranded person on the side of the road or kid after a ballgame. This thing has the power. This is at least 10 times more than my smaller unit. What else you ask? Well, it has a dedicated charger for inside as well as an adapter to charge from your lighter socket in the car. It has a flashlight. It has a USB port with 2.4A output at 5V. This is enough to charge your phone or tablet. My favorite feature is the length of the cables and cable management. The cables are long enough to reach the battery and the ground point on the frame. Then they can conveniently be wrapped over the handle and clipped on the side. Keeps things in order for the next time you need them. The other brand I had used really short cables. It was tough to get it positioned well when needing to jump. This is a great product with useful features. Use the flashlight when trying to jump a car at night. Power goes out, grab this and charge your phone to stay connected. And it has enough power to help jump multiple times before needing to charge again. You won't be disappointed.

    DSR in a small lightweight package
    The Schumacher Electric DSR ProSeries Automotive 12-volt 400-amp battery charger is perfect for many times you need a boost on any 12-volt system you have. It is very light to carry around and the large alligator clamps will hold onto anything very tightly. I love it for the lawnmower, or the motorcycle and it fits into the motorcycle saddle bag perfectly. on the tractor it clamps on tightly to the terminals on the starter motor for a quick jump. It has a built-in light to give you access when it is dark, or you can select a flashing light if you need a warning light in any situation. The state of charge indicator also alerts you if you do not have a fully charged battery pack. The pack also comes with a port to charge your phone if need be so you could say it does everything in a very small package.

    The "Beast"
    Tired of dealing with starting issues due to low or dead batteries? Especially on bigger engines that use 2 batteries.. This "DSR ProSeries Automotive 12-Volt 4000 Peak Amp Lithium Jump Starter and Portable Power Station" solved all of my problems. Small enough that i can barely fit it under the seat of my truck (Barely) Rated to beable to start up to 8.0 liter diesel engines.. assuming of course that they are using 12v not 24v This is just what i was looking for. It only has a few buttons on it that are simple to understand & use. The Cables @4ga. seem a little light however the mfg spec'd them that way. This is listed as a power station. it does have a single USB port that is rated at 2.4a. this could come in handy charging a phone when in need. Not like you would tote this around for that however if in the need and its on hand you have that option

    Beefy unit, very convenient to bring out to stranded lawn tractors as well!
    Great and powerful little portable jumper. It is absolutely perfect to keep in your car, or in our case i have it in the shed where my lawn mower regularly needs a jump. Easy to charge at home, or it has an adapter to charge off the power port in your car. I Have also used it to jump the battery on my moped, but I struggled to get the clamps to stay on the battery due to how the battery is set down in the moped. Took off a star for this as I was pretty frustrated trying to hold the clamps on my hand and also hold the clutch and start my moped. Wish there was a finer end to the clamps so it would fit on some of the smaller batteries better. But if you're just planning on jumping large vehicles this won't be an issue.
