When I was a young lad, it was not uncommon for cars to fail to start when you turned the ignition key. I'm not saying that this was an everyday occurrence, you understand, but if my mom tried to start the car and all we heard was a "graunching" noise, then we weren't outrageously surprised.

Things have become increasingly reliable over the years, to the extent that the thought a vehicle might fail to start rarely crosses one's mind. Thus, you can only imagine my doubt and disbelieve when I happily climbed into my new (secondhand) truck last Friday… and turned the key… and absolutely nothing happened (see also Just call me “Tracker Trucker Max” [Click Here], Now I’m “Truck-less Tracker Trucker Max” [Click Here], and My new moniker is “Tracker Trucker Max Esquire” [Click Here]).

Fortunately I still had my faithful little Kia sitting in the drive, so I set off for work mumbling and grumbling under my breath.

By some strange quirk of fate I'd arranged to meet my father-in-law for lunch that day. When I arrived at the restaurant in my Kia, he inquired as to the whereabouts of my truck. I explained what had happened, and also that I was going to wait till the following day and then get my son Joseph to help me push the truck into the drive so I could jump start the little rascal (the truck, not Joseph).

In response, my father-in-law delved into the tool box on his own truck and emerged clutching a yellow object that he said would make things a lot easier. It turned out this was a sort of "jump start in a box" type thing. Well, color me surprised.

Now you are probably already aware of these products, but I'm not really much interested in cars and trucks and suchlike – apart from their ability to transport me from point A to point B (and back again) – so I was completely unacquainted with the existence of these little scamps.

Anyway, to cut a long story short, the next day I used this "jump start in a box" thingy to start my truck, which I then took it for a 15-mile drive to charge the battery (I was working on the assumption that I'd left a door cracked open or a light on that had drained my battery).

I ended up at Barnes and Noble, where I popped in to check the bargain shelves for anything of interest. When I returned to my truck … the battery was as flat as a pancake. Fortunately, I'd had the wit to bring the "jump start in a box" thingy with me, so I re-jumped the truck and meandered my way over to the nearest auto-parts store. They attached a special meter to the battery and informed me that it was as dead as a dodo – it had gone to meet its maker, as it were – so they installed a brand-spanking new battery for me and I headed on my merry way.

I have to say that I was incredibly impressed with the whole concept of these "jump start in a box" thingies (do they have a proper name?), so the first thing I did was to drive over to my local Lowe's Store to see what they had to offer in this department. They had an entire rack of this type of product (how come I've never noticed them before?), and I ended up purchasing a Stanley PPRH5 450-Amp Professional Power Station with Built-In Air Compressor:


This little beauty is GREAT!!! In addition to the 450 amp/1000 amp peak jumper capability, it also comes equipped with a 120 PSI digital piston-driven compressor. Once again, it’s not like you need this capability very often; on the other hand, my wife (Gina the Gorgeous) is a realtor specializing in new construction, which means she spends a lot of time driving around new developments. In turn, this means she has a habit of picking up nails (not her, but her car's tires) resulting in slow leaks (again, I'm talking about her tires). The bottom line is that it will be really useful to have this portable air compressor at our disposal.

But wait, there's more, because we get a lot of thunderstorms around here, and it's not uncommon to lose power for a couple of hours. Of course we have candles and suchlike, plus we have a supply of batteries, but losing power can still be a pain ("Especially if you've failed to charge your iPad that has all your music and videos on it," he said, bitterly).

So I'm really happy with the fact that my Stanley Power Station provides a high-powered ultra-bright LED emergency light along with two 120-volt AC outlets and a USB power output, all of which I am sure will come in very handy in the not-so-distant future. Now I'm just waiting for someone to say "Excuse me, do you happen to have any jumper cables," so that I can proudly whip out my Stanley (hmmm, maybe I'll have to re-think how I say this…)

Just don't forget to charge it!

The first time you plug it in it says to charge it for 40 hours. After that to top it up once a month.

I keep it in my truck on the floor in the back. I'll top it up the first weekend in the month (I do a bunch of stuff the first weekend like changing the air filters in the house -- always doing things that first weekend makes it easy to remember things)

That looks quite heavy, I am wondering if it is easy to move around. I do think that having it (or something like it) is a great idea!

It' snot light, but the furthest I will have to carry it is from the floor of the truck to the power socket in the garage (unless there's a power cut, in which case I will take it into the house) ... but that's no "biggie"

What I don't "get" is that obviously the battery in your "stanley" is not that big - around 25 Amp hours at most, much less than the normal battery, so how do they manage to crank a big engine like your truck? Are they special batteries? Anyone know about these things?

Low current, high voltage, static inverter or buck converter. Just guessing. Maybe even dynamic inverter.

In typical battery has enought energy to start engine after keep headlights on for few (not many) hours. This device is mainly used only to start engine, for this needs only to supply few seconds of 100-200A current. In this case big battery is not required, small will be enough if have small internal resistance.

@David" It's not the size of your "Stanley" that matters ... it's what you do with it that counts!

I believe they use AGM (adsorbed glass mat) also known as gel-cell batteries. They tend to have a lower internal resistance, and so supply more current for a relatively low amp-hour (and weight). Also, you don't have to worry about spilling them.

Like other leand-acid cells, they like to be kept charged, but discharge isn't so bad. The glass mat keeps the lead from falling off and shorting the cell.

Last year I replaced the Diehard in a Caravan, and when I brought it into the store, asked how old it was. The dealer was surprised to say it was only 2 years old, when I then figured it was 12 years old! (There is only one digit year in the date code.)

I put an AGM battery in an Odyssey when the OEM battery died after 3 years. I recommend them.

My Stanley is my neighbour's car :-) I called upon his car's services on a couple of occasions in the past 3-4 years to jump start my car's engine. On both occasions, I left the flood lights on over a week-end :-(

Now here's the problem, an average car battery lasts about 3 years+. The batteries in the jump starter will likely last only 2 years because they don't get cycled, so in 3 years when you next need your jump starter, you may just need to borrow someone's jump stater :-) They're a great idea for mobile mechanics and the likes, but not really for an individual. In fact the Kia you have is probably a better option for your truck and vice verca :-) That said if you use it frequently for emergency light and power the usefulness equation is a little different.

For anyone interested, I designed an all singing all dancing jump starter for a company that had an integrated Buck/Boost converter for charging and had 2 x 12V high capacity batteries (for their size) - about 44AH each. They were switched in series or parallel for 12 or 24V systems. Obviously you will only start a truck a few times before you won't anymore :-) but the concept does work.

I always read the 5 star and 1 star reviews on Amazon. The two 1-star reviews were pretty bad. At a minimum, it convinced me to buy at Lowe's (I hate home despot) and test this out in the first week or so, when I could easily take it back.

I liked the suggestion of extending the air hose. I think it was on one of the 4-star or 5-star reviews.

I have to ask: WTF is a "digital piston-driven compressor"? Is it one you push with your fingers?

Do you know, I wondered that when I read the description on Amazon, but then I thought "Life is too short to worry about it -- if I needed to know then I would already know" :-)

I wonder if there will be the day when car provide a cigarette-lighter or some other standard DC connection in the trunk that allows a backup means to appliances like this. Although, I have started to notice the cabin starting to sport power and audio path for consumer devices.
I am waiting for the trunk to get the same attention. Is it only me that would like to see this?

The day is here, but it probably depends on what vehicle you choose. Our Ford Territory (an Australian SUV, launched 2004) has a ciggy lighter socket in the rear, presumably for a portable refrigerator.
