(originally written for a solar power forum, but applies here too) OK, I wussed out, and bought a commercial product! We have a small sleeping hut built on the ranch now, but no power in it yet. It's going to take a while to mount a panel, batteries, charge controller, wire up lights and such, and we arrive at nighttime, and no where to plug the CPAP in ! So I spent a couple days pricing out different ways to accomplish this, and settled on a portable jump start pack. Found a model with good reviews (Peak PKC0AZ 450), and no air compressor (that often fails after 50 total minutes of use). Located one in stock at local autoparts store, and bought it, taking a chance it's been parked in a warehouse for a year, and then in the back room for 2 more years, resulting in a flat, sulfated battery. (fully half of the complaints at Amazon)Other choice was to get a AGM battery, rig up a case, cigar jack outlet, charger and hope it still fits into the car.Upon opening it up, and throwing a voltmeter on it, I was pleased to find it reading 12.85V on a warm afternoon. It's built-in indicator showed it was 4/5 charged - also good. I plugged it's wall wart (transformer, not switcher, 12V, .5A) in, and let it top it off for a couple hours, it came to quiescence at 13.37v, and I unplugged it. After an hour, it read 13.13V. Awesome! And the Respironics power cord (for the CPAP) appears to fit snugly into the Lighter jack.Using my kill-a-watt before I was shopping, I'd discovered that the CPAP consumed about 75 watt hours in a 6 hour run, and that for 2 nights, I'd consume about 12.5 ah of battery. The "450A packs" claim to have an 18AH AGM battery in them, but I figured, I may as well have a portable unit, than a hulk that will last me a month. And if I only ran it one night (6.25 AH consumed) and then recharged, it'd live a long lifetime. Well, the power brick for the CPAP is a pig. After running all night (6 hours) , the voltage in the AM, read 12.66v Whoo hooo! Internal battery indicator LEDs still showed 4/5 charge, way less drain than the power brick used (all my testing is done with humidifier OFF) so even though the brick read about 3 watts idle, it was using more with a light load.So, this will recharge at my shop, and I think I'll get a plug in lamp timer, and set that for a 1 hour charge daily, to keep it topped off between visits. And since the shop is on solar power, now my CPAP is too!Added benefit, the power pack has a LED lamp built in, and a USB power port, so I don't even need a cigar plug Y cord to charge my phone and PDA.So, I've owned this less than 2 days, but I think it will do the job I need it to, and it's not DOA out of the box. It can also charge via a running car too, but I've not tried that yet, I think I can also feed it from a 3 stage charge controller set for AGM. And it can jump start the tractor too, if I need it.And it was a lot less than the $$ soft side 14ah CPAP battery pack. I hope the AMA does not come after me!

I purchased this with the purpose in mind of using it as a portable power source for things like when I go camping it can provide power for lights, an air mattress inflator, etc. The battery rating of "18 amp/hour" tells you it should be able to run something drawing ~18 amps for 1 hour, 9 amps for 2 hours, etc. I've even tried using it to power a small inflatable boats trolling motor for over an hour and it didn't drain it, but I mainly kept the motor on the low setting (using ~8 amps, high would use ~15 amps but I used that only ~10 minute of the time I was out).Note July 2013: New units are out with a digital display of battery level (showing % of charge) and has the charge unit built in (with no "charge port"), so the things I've said about those items may have changed if you're ordering one now.The only issues I've had with my unit (why I dropped 1 star) is for charging it, I've had to send power thru the lighter outlet or main jumper cables. The red LED indicating "charging" comes on with it plugged in to their "charge port", but after leaving it plugged in for an hour there was no increase in voltage. I connected up a charger to the other places and instantly saw "12.75V, 12.76, 12.77, etc" (about at the same rate you can say those numbers out loud) showing it was actually charging (and FYI I still used a 500mA charger like they provide, not a 10amp or such). Also the switch for the outlets doesn't turn them off, but they pass power fine. Update Dec 2012: I got the guts to open up the case and on the back of the circuit board, I saw a line of solder going across the switch terminals for the "power outlet" switch. I'm 99% sure that shouldn't have been there, so popped it off and now the switch turns off the outlets. Still not sure about the charge issue though and didn't want to risk breaking the circuit board trying to dig too deep. I got another of these (but the model with the air compressor) for my sister and it accepts a charge thru the "charge port" normally, so it seems a random problem.I've found that the battery indicator LEDs come on as follows:While something's in the "charge jack" (to tell the unit that you're charging it) the red LED shows with under 12.75V, the yellow LED shows for 12.75-13.1V, a green LED shows for 13.1-13.5V and 2 green LEDs show for over 13.5. If nothing is connected to that "charge jack" (hinting you're draining the battery) the red LED shows for under 11.6V, the yellow shows for 11.6-11.9V, a green is on for 11.9-12.25V and double green show for over 12.25V. Those make sense to me because 13-14V is fully charged and what you want to measure while charging, yet down in that 12.5-11.5 area is what you want to measure while draining.This has a switch for the main "jumper cables" that eliminates arcing as you hook them up and it allows the unit to have a "reverse connection alarm". That alarm sounds if you hook them up backwards before you turn it on (and should prevent an explosion that could result). Without the switch you can't have that alarm and you can't "turn off" those cables (a review of another unit without a switch says "a fire started in my car since the cables are always on and touched each other"). That switch may add a bit of resistance during a jump start and another step to remember to do, but those safety features are good to consider as well.As far as it living up to it's title of "jump starting" a car, I have doubts. Just like this battery is ~1/3 the size/weight of a car battery, you won't get but about that much power from it (and the labels like "450 amp" or "900 peak amp" are just a big salesman lie to make it sound big). My proof is from connecting up a 100 amp battery tester to it freshly charged, the battery drops to 9.5V under that load for 5 seconds (and that power draw is close to what a small car starter needs). I was taught in shop class that a car battery should keep 10.5V under 1/2 it's CCA load, so this doesn't pass as even a 200 Cold Crank Amp (so how do they get "450"?).Update Oct-2012: I tried starting my Ford Festiva (4 cyl) with this alone on a morning with it ~40 degrees out (disconnecting the car battery to partly simulate a dead one). It did start it, but the starter was slow just barely being able to crank it. I tested my car battery the next morning and it's labeled as 500cca, but passed as only a 200cca (showing I need to replace it soon). After doing that test I started the car and didn't notice anything abnormal (with the starter going much better than on the Peak unit alone even after the drain from the test).The cars battery condition will also play a big role in whether or not this can "boost" you enough to get you going. If a cars battery is pretty weak (like from leaving your lights on while you went to a movie for 2 hours) but can still provide some power, this can give you some extra power and has a fair chance of getting you going. But if a cars battery is fully drained (like from leaving lights on all night long) and you hook this up to the fully "dead" battery, the dead battery will instantly start "stealing" power (to recharge itself) & probably drain this before you can even get from the hood to the driver seat to start the car. In that situation I doubt you'll get started without another full size car battery or a charging source for 20+ minutes (an a/c charger or car & jumper cables).

I purchased this thinking this was an outright 900amp unit, when I went to pick it up (Advanced Auto)the unit stated 450 starting amps and 900 peak amps, obviously no one was able to tell me what that meant. But I kept it in the spirit of giving it a try. At home, I was able to take a closer look, to see the features. A switch for some workable LEDs, not to bad when you don't have a flashlight around. the DC plug, though I didn't use it yet, looked good. Nice rubber bottom on the unit to help it stay in place. After putting it through an 18hr or so charge, I plugged into a work van (Ford V8) that had a completely dead battery. Hooked up the unit to the battery, and ... nothing. Though I did hear the buzzing noise that my key was in the ignition, just not enough to do anything else. Now I left it for about 20 min. Didn't know if that was either enough or I had it on longer than needed or not enough for that matter, but came back and tried it again. I got into the van and this time the starter was trying to engage, and I kept cranking, either it was going to turn over or die on me again. Well it finally did turn over, which means I will be holding on to the unit, since the other two cars I own are 4 cyl. I have not plugged back into the charger I will see how it runs its course. But simply impressed enough for the price. I did get it at AA over than Amazon was purely price, a preblack Friday special of 50.00 which I thought was excellent at the time for 900 amps... which is really 450 starting amps.
