I have owned almost every aftermarket charger out there from Retrak to Insignia and others I couldn't even pronounce the name. This one is by far my favorite for a few reasons.
#1 and the BIGGEST reason I am loving this little guy is that it actually charges my Dell laptops (inspiron, latitude, new, old) like it should! I know that doesn't sound that impressive (it's a charger so it should charge it you say) but considering Dell builds into their chargers a specific circuit to enable the laptop to recognize the charger as a "Dell" charger or not, it is a HUGE deal. Whatever person engineered this beauty, they did it right!
#2 A great (small) size and well thought out for travelers. Besides the fact that the power "prongs" swivel into the case for a flush design when packed away, the charger itself is quite aesthetically pleasing.
#3 Works in every country I have tried it in. Of course you may need the USA to whatever country you are in adapter to plug it into the power source still. Other than that, this thing handles every standard power output like a champ. I have even ran it off a generator without the power being conditioned too well (spiky) and it performed terrifically.
If this thing came with a retractable cord it would best the best designed adapter EVER...
