I was going on a car trip and had just bought a GPS unit for my Dell Inspiron 1720 laptop along with the Delorme Street Atlas software. Since I was going to use my laptop as my GPS navigator it would have to be on all the time, so I needed a way to keep the battery charged in the car. I there for purchased the PWR+ charger from Amazon.

The first thing that stuck me about the charger was that it looked almost exactly like the OEM AC charger that came with the laptop. Instead of a AC plug on one end, it had a cigarette lighter/power socket adapter. It has the exact same voltage and wattage output as the AC version. The quality of the workmanship was heads above all the other adapters I looked at on the web, but it only cost a few dollars more. I used it for many hours at a time for several days and it performed flawlessly.

This was well worth the money. -- 12V car charger for Dell laptops

This item is a must have for any long trips in the car. On vacation, it kept the laptop going the whole trip so that we could play games, listen to music and get any other info we needed. Highly recommended. The plug into the car adapter was not as snug as we would have liked so had push it in once in awhile. -- Terrific buy!

Needed an auto adaptor for my laptop so my daughter could work on a school report while we were driving during our vacation. This one worked perfectly. -- Just what I needed.

I love my charger, it works on both of my Dell laptops with no problems. Would recommend. -- Love this!

Generally, this DC charger works in my car. However, if my Dell Inspiron 1720 laptop goes into "emergency shutdown" because I've drained too much battery power, and then I try to charge it with this DC adapter, it doesn't charge. I don't have this problem with my AC power brick, so I am inclined to think it is the fault of this DC adapter. Workarounds: (1) don't let the laptop get so low that it goes to "emergency shutdown," or (2) plug it into the DC adapter, power up the laptop, then close the laptop lid. This gets the laptop out of the "emergency shutdown" state and allows charging to proceed normally. These workarounds are acceptable in real world use. I just find it annoying that I had to figure it out. Things should just work; that's why I bought a Dell-specific DC charger.

The plastic case came apart. One half of the housing has plastic screw posts, for the other part of the housing to screw into. These plastic screw posts simply separated from the screws. As an immediate remedy I wrapped the velcro cord holder around the case, to hold it together. In the future I will probably duct tape it. I am doing a lot of camping right now and am traveling most of the time. I don't have time to return it for a new one.

I would steer people towards a competing Dell-specific PA10 DC charger, if I knew of one, but I don't. This seems to be the only game in town. The alternative is to use a DC-AC power inverter and a standard AC power brick. Theoretically this wastes electricity compared to a straight DC connection. In practice, my laptop charges at a rate of ~40W while the laptop is open and running, using the DC adapter. An AC adapter also charges at ~40W, when running. I'm not sure of either case when it's turned off. I don't know how much power it's drawing, and then wasting, to achieve that 40W of charge. A fully charged car battery is 12.75V but diminishes as it discharges. The charger draws a max of 5.6A according to the label on the back. So, waving hands and blowing off non-linearity, it could be drawing 12.75V * 5.6A = 71.4W to achieve 40W of charge. That would not be a terribly efficient charging scheme, although I don't know what it actually does, or if the rate of charge is > 40W when the laptop is turned off. If this DC charger goes belly up for any reason, I will try a power inverter and a standard AC brick next time.

In a camping context, wasting electricity actually matters. I recently bought an Odyssey deep cycle battery to replace my standard car battery. That way, I can camp for a few days and not drive anywhere, instead of having to drive around to recharge my laptop. Standard car batteries are not designed to be drained much; you will kill them quickly if you charge while you're not driving. At 40W it takes ~2 hours to charge my 9-cell 73000mWh laptop battery. If I have to drive around to do that, that's a lot of gas, and a fairly expensive way to get electricity on the road. I'm planning on doing entire 8..10 hour work days of computer programming while on the road, not just a little bit of laptop here and there. With the deep cycle battery I may only have to drive 20 minutes to recharge the car battery, because big fat cables run from the alternator to the battery, instead of little wimpy DC cigarette lighter outputs. Then I have 2 days worth of electricity and I can just plug my laptop in to recharge whenever I want, I don't have to be driving. Driving 20 minutes every 2 days makes a lot more sense for generating electricity.

UPDATE 9-1-2010

The charger worked fine with the broken case. However, 2 weeks after using it, my Dell laptop stopped recognizing it or any other charger. It seems that the recognition circuitry on the motherboard fried. I have no idea whether the charger caused this to happen or not. The Dell recognition circuits are cheap junk and known to fry on their own, particularly after 3 year warranty periods are up. If you do a web search you'll see that this problem with Dell recognition circuits is widespread, pretty much class action lawsuit territory if someone would get it organized. Because I could no longer use the charger to charge my laptop battery, and because its case broke, I returned it for a full refund, including shipping and return shipping costs. My account has been credited and I am satisfied with the 1 year warranty that was provided. I would consider buying a PWR+ product again, but I will never buy a Dell laptop again, so long as they have a proprietary charging system.
