Pros: No buzzing sounds when idle or in operation
Stable voltage
Tips for everything (except Apple MagSafe)
Tips fit tightly and do not fall off
Quite efficient, does not get hot unlike my old adapter

Cons: AC cord is a bit short

Overall Review: Replaced a very noisy Lenovo adapter that was generating a great deal of buzzing and whining noises,

Pros: Great charger if you plan on using the charger on *ONLY* one laptop. *SEE CONS*

Cons: connector pins will easily crimp shut effectively rendering this product worthless. I run a computer repair shop so I purchased two to keep on hand for when customers forgot to bring their own chargers. Each chargers connector pin slots have crimped shut after 2-4 adapter changes.

Overall Review: Over all I will say that if your laptop is within power specs, this system will charge it, however... do not purchase this if you intend on actively switching adapters on this charger as I have no faith that it will last.

Pros: Seemed like a good deal, had a lot of connectors on it for laptop repair i thought this was going to be a sweet deal.

Cons: The 4 pins inside where you plug the different adapters in easily bend without you doing anything to cause it. Once that happens it will not function.

Overall Review: I am going to contact rosewill and see if they will fix this, they should come up with a better way to secure those connectors to the charger, there has to be a better way this way its so easy for it to mess up.

Pros: my laptop's power adapter broke, almost dropped the $60 on a replacement then thought i should try out a universal adapter instead.

so much better deal! also plug stays on very securely so I don't worry about it falling apart when traveling.

Cons: don't loose the paper explaining what adapter fits what brands...

Pros: Inexpensive, lots of tips to choose from, tips fit very snugly so as to avoid falling off during normal use. works find on every computer I have tested

Cons: the price for this item seems to be all over the place. the first one I purchased was $15. now it's $30. I got one not long ago for $19. wish they'd just make up their mind....

Overall Review: got this as a replacement adapter for myself. purchased 4 more of them over the years as cheap replacements for friends. makes a really awesome gift to someone who's laptop charger is broke.

Pros: I've used many of the universal chargers out there. This one works well and will not trigger the adapter warning on a dell. No problems.

Cons: Does not fit the new mini hp connector.

Pros: 1)I have purchased approximately 5 of these in the last year and every one worked as advertised.
2)90 Watts is a lot more compatible than the 70w version as more laptops use 90watts these days. This one is 90w.
3)Auto sensing. Automatically adjusts to your laptops usage requirements
4)Lots of different tips for many different makes and models of laptops

Cons: 1)Does not have tips for the newer HO laptops which have been out for about a year now

Overall Review: Overall, its a lot cheaper than buying a manufacturers unit and is more versatile.

Pros: NONE!!!

Cons: FAILED after 2months. GETS TOO HOT while charging!! CHEAP QUALITY!!! UNRELIABLE!!! LOOK ELSEWHERE!! What a waist of money for a product that does not last.

Overall Review: I bought this charger back in November and it started to fail within 2 months. It DOES NOT charge unless I keep the wire in a certain position. I constantly have to wiggle the wire in order for it to charge. It also tends to get too hot when I'm charging my laptop. If I could give it 0 eggs I would but I have to give it 1 egg. You've been WARNED!!! DO NOT BUY!!! Spend your money on a better quality charger.
