I connected both the iPad and speakers to this charger at the same time and they both worked fine. I watched a video on the iPad while listening to the speakers at a high volume to determine if the charger can handle it. It not only handled the load without any problems, but it also charged up my iPad to a full charge.
I discovered that there are two versions of this PowerBlock Dual Universal Charger. This one provides 1 amp per USB port and the other one produces only 500 ma per USB port. The good one advertises the 1 amp per USB port capability, while the other one does not. Also, this one shows the 1 amp per USB port on its packaging and on the unit itself. By all means get this better one, not the less capable one, as it can handle more devices.
I travel a lot and needed a small lightweight USB charger that can power my USB speakers, which saves weight and space. This can help avoid paying overweight charges at the airport which can be quite expensive (some portable speakers have a heavy power supply or built-in rechargeble battery that you must carry around). Also, I like the fact it can handle an input of 100v-240v so it can be used in any country.
Update: My daughter liked this charger so well that she got one for herself to power her iPhone and HP USB Mini Speakers. These mini speakers produce great sound from the iPhone, and this charger will power the mini speakers and charge the iPhone at the same time.
Update: Beware of purchasing this charger if you want the 2amp - 1amp per port charger. When I purchased this charger in 2010 and another in 2011, the title included the words (2amp - 1A per Port). There was another identical looking charger for sale on Amazon at another webpage which was 1amp - 500ma per port. Since they looked the same, some Amazon sellers confused the two and sold the 500ma per port instead of the 1amp per port charger that was advertised on this webpage. So how did Amazon correct the problem of Amazon Sellers selling the wrong 500ma per port charger on this webpage? They removed the words (2amp 1A per Port) from the title of this webpage! Now it is the customers fault if they get the wrong one, as Amazon removed all references that this is a 2amp - 1A per Port charger. The Exact Words of the previous title was "Griffen PowerBlock Dual Universal Charger for MP3 Players and USB Devices (2amp - 1A per Port)(Black)"
I no longer recommend buying this product from Amazon.
Upon closer examination of the powerblock itself, it states 1 amp total. So clearly there is a problem with the maufacturer. Their packaging says one thing, while the block says another. So I can't blame the seller since they sold the correct item. So be wary and let's hope you are not the unlucky one that has the right package and wrong block.
I own alot of griffin products and swore by them, but this is disappointing.
