Is it safe to buy a generic laptop power cord?

bosstone75 411 61 May 15, 2011 at 10:57 AM
We need to buy a new power cord for my wife's laptop. I don't want to pay full price, but I also need it to be safe. Last time I got a cord for my laptop it got so hot it melted a bit. (to be fair it was a bit restricted in its airflow -but still...)

Any thoughts on the safety of generic power cords and/or places you've gotten good cords?

Her computer is an HP G60

Thanks!

Hi, I would never buy the $10 ebay ones they get super hot and are contructed poorly.
I have had success with the universal targus apa69us which can be had on ebay for about 20-25 dollars. get a new non-refurbished unit and you can register it for a two year warranty. Targus also sells the apm69us which includes an auto adapter. I also recently purchased an acbel slim adapter from battery1inc on their amazon storefront. Great unit, ultra slim, gets very warm but not too hot, BUT has a very short cord. Lightweight for travel. Acbel is a well known OEM manufacturer.
I would also look into the universal chargers from antec the np-90 or snp-90. In general go with known brands targus, antec. Stay away from the ebay junk. Lots of the auctions on ebay even though they claim to be selling OEM they are knockoffs - they just print HP on the adapter. Not worth the risk.

Thanks you two.

The one I bought for my laptop that melted was from eBay, so it's good to know there's other chargers out there that aren't a fortune that will work.

My wife and 16 month old child thank you too!

Careful with the amazon one, there are tons of sellers there so its hard to know which ones are ok. I would really go with a known brand.

Yeah, I THINK maybe one key thing to look for is a 90 Watt adapter vs a 65 Watt adapter. I've been doing a bit of reading that the 65 Watt adapters have to do a little extra work and so heat up more. That seems to make sense with what I've experienced. I agree though. I'm a little skeptical about buying a power adapter for under $4.00.

I'm just about to pull the trigger on this one...

I'm also looking into one of the universal ones that you offered up as a back up for our 3 laptops. I've been wanting to get one of those for awhile now anyway. Question is... is $20 more worth it for a car adapter... we already have a limpy inverter that allows us to power the computer in the car, but it might be nice to have an all in one. Dang I'm terrible at making decisions.

Thanks for your help.

I know with Dell - if you buy a non-OEM replacement it might refuse to charge the battery, but will power the laptop.

Think that applies primarily to Dell's that require a 90w power adapter. Those that used a 65w adapter were not fussy. Fry's actually has a SIIG 90w universal adapter FAR this week, but there is no Fry's near MN. You would probably not want to purchase such an item since it would not be easy to return it if it does not work with your HP.

Just thought I'd share my experience with you. When I accidentally broke my HP ZV6000 laptop cord, I went on ebay and bought one of the cheapish ones ($20, it was cheaper than the $100 official ones). It worked and did its job but the power brick ended up melting. After that, I have never and will never trust generic chargers again. If you do decide to go with one, make sure you don't leave it plugged in unattended as it might be able to cause a fire in your house. If you look around you can get universal adapters for ~20-25 and they are made by name brands, I got one from Targus at fry's for like $20.

Good luck.

I have many power bricks for all kinds of devices, all bought off of ebay and never had a problem since 1996 (buy from reputable sellers). Every time I get a new portable device, I get a new cheapo power adapter for it and either use it, or the original at the office or home, or vice versa.

If the laptop is overheating and melting power bricks, it's usually the the power jack on the laptop that is 'loose'. A bad ground or +V terminal where the power jack meets the board with cracked solder joints is usually the culprit. The bad connection causes increased resistance, overloading the power adapter.

It's 'usually' a cheap fix.

I agree. I've bought many generic brand power cords with bricks within them from Ebay. Always from a reputable seller and always exactly the specs of the one I want to replace. Never a problem. Look at the brick on the one you want to replace and get the specs off it, or look at the manufacturer site and get the specs of it there. Buy according to those specs and don't go lower -- you will be fine, unless you have a bad jack on the machine itself. Most users, IMHO, make a mistake in buying a cord that is rated less than the one that originally came with the machine. Do your research and buy the correct cord for your machine.

My experience has been that the "end" that plugs into the jack on the computer goes bad more often than the actual "jack" on the machine. It gets bent around and pushed around and the wires break in than "end", causing the laptop to not charge the internal battery.

Thanks for all the info folks. Reps all around!

Dr. J and WackyP - Ugg... that's good to know. I may just not be buying a Dell just for that reason. I hate when companies put things in place that limit your options.

Zodiac - that's pretty much what happened to me with a previous eBay adapter, but in looking back, I think I had bought a 65W that claimed it would work with my computer and I should have had a 90W

G37 and callpocket - thanks! I might give cheap generics a try again using your advice. This was for my wife's computer though, so I decided to get more of a sure thing because I know she might leave the box wedged in between sofa cushions (I know... never a good idea)
