I wasn’t even aware that a product like this existed until I stumbled across it on Amazon. Before I go any farther, if you are thinking about getting an auxiliary jump-starter for your car, get this one. NOW! You will not regret it. So here’s my background. I drive a 2013 Buick Enclave with a 3.6L V6 with a SprawlMart battery that has been a constant disappointment in temps below 10°. After several times of being late for work, I decided to look for an alternative power source. I was tired of the embarrassment of desperately begging neighbors and strangers to jumpstart me. In fact, I was searching for a new battery here on Amazon when I stumbled across this capacitor bank and thought I would give it a try. Best hundred dollars I have ever spent!!! So far, I have used it three times in temperatures below zero and it has successfully jumpstarted my car every single time the first time in spite of my frozen/dead battery. The beauty of this device is that it charges itself in just a few minutes off of your dead battery! So, as long as you have a working voltage of 3 Volts or more, and most dead car batteries can supply at least twice that much, it will charge the device just fine. This means I’ve been able to jumpstart my car in LESS than ten minutes each time. Let’s see you do that with your jumper cables. And speaking of cables, the wires on the device are small and easy to use in freezing-cold conditions. So how does this work? Well, first, you need to understand that this device is not a battery. It is a bank of capacitors. If you don’t know what a capacitor is, go Google it and learn from that because I don’t have time nor space to explain that here. All you need to know is that this a solid-state device that is able to store up enough current quickly in order to start your car. Now let me clarify something about my car. My 2013 Buick Enclave is a wonderful car in that it has started the first time every single time (with a good battery). So this jumpstart device works very well with it. Having said that, I have not used this device on a vehicle where you have to grind the starter a lot, so I cannot attest to how well it will perform on a vehicle that requires a lot of churning of the starter motor. So, if your vehicle is of that nature, then I would recommend getting the device that has the higher CCA capacitance. In conclusion, I could not be happier with how this jumpstarter device has performed for me. I highly recommend it, and I know you will not be disappointed. It’s so simple, even a caveman can do it.

Well, it does what it is stated for. Unlike battery jumpers, this could sit in your car for months and still work when you need it. It will not work if your batter is completely dead, but if you find your self in that situation, it can still be hooked unto a strangers/friend battery to charge. It can also be hooked up to a lawn tractor battery to energize. For the cost a case of some kind would have been nice. I purchased this one that fits pretty well, https://www.amazon.com/dp/B08Z2SC72H?psc=1&ref=ppx_yo2ov_dt_b_product_details. The rubber case is held on with screws and a small washer, the washers are too small and the rubber pops off really easy, I took the screws out and put a slightly larger washer on them. It takes a rectangular screw driver.

This is a very good product. It uses super capacitors instead of a battery. I like mine a lot and have use it several times. My car has a very small battery (like imagine the size of a lawn mower or motorcycle battery) so it is prone to dying suddenly without much warning (thanks car engineers!). The pack rides with me in the trunk all the time, and it has saved me from waiting for AAA late at night, or in the rain a few times. Before this I was usually stuck begging for help from strangers (which dosen't work so good in 2018) or waiting maybe an hour for AAA under the best circumstances. With this pack I can get going, on my own, in about 5-7 minutes max. The advantages are: 1) You can usually get yourself running, without help, even if the pack is completely discharged AND YOUR CAR BATTERY is nearly dead in under 7 minutes. Seriously...think about this...Its like awesomely awesome jump start magic with super awesome sauce on it! 2) The super capacitors can accumulate charge off a nearly dead car battery (I think 2.5-3 volts minimum) in a short amount of time (like 2-3 minutes max) and then discharge all the absorbed energy all at once in a few seconds to jump you. 3) The pack is light weight (compared to a lead acid setup) It weighs about 5 lbs. 4) The pack wont "wear out" like a battery, and charge and discharge cycles don't effect super capacitors (10+ years of use or 10,000+ uses is a realistic lifetime for a device of this nature, and probably way more). 5) The pack charge up times and discharge amperage output are not impacted by temperature (this thing charges fast, and pumps big cold cranking cranking amps when in sub zero cold temps, or ultra hot desert temps). 6) The pack form factor is relatively small, its about the size of maybe a hard cover dictionary (remember those?). Its easy to toss in the trunk and forget about till you need it. 7) They printed a summary of the usage instructions on the back of the pack so you don't have to try to remember the little steps. 8) This is revolutionary jump start pack technology, and it really is totally awesome! The disadvantages are: 1) Cost is a bit high. Given the theoretical lifespan this is probably a one time hit (how they say: buy once, cry once?). 2) A little different than using jumper cables or a lead acid jump pack - gotta charge first, and have to let the pack refresh charge a little between cranking attempts (if the first attempt dosen't turn the car over). Once you get used to it, this isn't really an issue though. 3) 12v systems only I think. 4) The pack discharges itself relatively quickly - minutes to hours maybe days. Since it charges so fast off a nearly dead battery, this isn't really a significant issue. 4) It would be nice if it came with a fitted case....or pouch. 5) It would be nice if the cables and clamps could easily "disconnect" from the pack body...they are kind of odd, dangling off like they do, all in the way during storage, and what not, and not long enough to wrap around the box and about that cable length....I might have made the clamp cables a bit longer so the pack could be placed on the windshield of the car so you can see the charge status lights while you are sitting inside the car (you know - while it rains outside the car). For me the disadvantages weren't worth subtracting a star. Purchasing wise, Amazon was awesome, as usual!
