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.
I typically only use it to charge one device but it works if you want to charge 2! I love that the prongs fold up. It makes it great for travel. Also, the prongs are the same size so you can put the charger into an outlet right-side up or upside down, which is nice when you have other bulky things charging at the same outlet. I generally use it to charge my iPod touch, iPhone 6, and/or portable charger.
Input: 100-240V~50-60Hz 0.4A
Output 1: 5V 1000mA
Output 2: (same as output 1)
Griffin PowerBlock Dual Universal Charger for MP3 Players and USB Devices (Black)A portable USB charger should be simple and straightforward device. It should plug into an AC socket and charge one or more USB devices. I use an Android phone and a bluetooth headset constantly. These two USB devices require charging, and as a result, I need to keep a charger with me at all times, whether I'm commuting to work or traveling. When I began researching portable chargers, I began by considering the basic requirements I'd have for a charger that I'd need to have available for use every day, and regardless of my location. Here are the requirements I came up with:
A portable charger should be small enough to fit conveniently in the outside pocket of my backpack.
If the portable charger is going to ride along in the outside of my backpack, it ought to easily withstand the rigors of travel for several years.
Simple and reliable
A portable charger really doesn't need many additional features. Plug it in and it works. Period.
A portable charger should be able to charge at least two devices simultaneously. It should also be able to charge any device I typically travel with, including an Android phone, a bluetooth headset, and a tablet.
The Griffin PowerBlock Dual Universal Charger appeared to meet all these requirements when I purchased it three years ago. The charger is a simple device with only one moving part. The AC plug blades swing out when the device is plugged in, and fold flat when being stored. As the AC blades are the only moving part, they were also my biggest concern concerning the usable lifespan of the charger. Over three years, the blades have always folded without a problem, have not developed any play in the hinges, and continue to function normally.
The charger has one green LED light on the front to indicate that it is plugged in and ready to charge. It has two USB connections, allowing the user to charge two devices concurrently. The price of two USB cables (not included) actually exceeded the price of the charger. I've found that Monoprice.com is a good source for inexpensive USB cables (and a large variety of other electronic items as well - I've provided the link below). I use velcro tie straps to organize my cables, and the charger is small enough to allow me to fit both the charger, and two USB cables, to fit conveniently into the outside pocket of my backpack with room left over.
Price and quality
A major consideration for any portable charger are the amps and watts it generates. For instance, an iPad charger generates 2.1 amps and 12 watts. If your charger does not generate this much power, it will charge an iPad much slower (or possibly not at all). Other devices, like a phone or a bluetooth headset typically have lower requirements, but you should check the amp and watt requirements for all the devices you plan to charge before purchasing a portable charger. Another aspect of a portable charger to keep in mind is that, in many cases, when you are charging two USB devices concurrently, the number of amps and watts may be divided equally between the two devices. In this case, if you have a 2 amp, 10 watt charger, and you're charging two devices, the charger may only be able to provide 1 amp and 5 watts per device.
The Griffin Technology website reports that this device provides 5 watts to each USB port, which should be enough power for almost any cell phone. However, it is not equivalent to a standard iPad charger. I've provided a chart I found on an Apple discussion page, as well as a link to that page, and a link to Griffin Technology's website in my complete review (see link below).
The price is very reasonable at around $14.00. The price is only reasonable if it works reliably over an extended period of time, of course. In this case, the charger has worked perfectly after being bounced around in the outside pocket of my backpack, every day, over a period of three years. I liked it so much that I also ordered the Griffin Mini USB Car Charger (which also has two USB connections). This device has also worked perfectly over three years of daily use. Based on my experience with two Griffin devices, I'll definitely be buying their products again.
The Griffin PowerBlock Dual Universal Charger is simple, elegant, robust, portable, reasonably priced, and charges USB devices simultaneously. I'll update this review in 2016 and let you know if it's still running.
