This review is from: AmazonBasics 2-Port USB Car Charger with 2.1 Amp Output (Black) (Electronics)
I have been using it since last two weeks now. This is simply awesome product.
I have used "Griffin Powerjolt Dual Universal USB Micro" before and AmazonBasic is much better than Griffin for following reason
1) Design: Griffin is so small that it gets stuck in the car charger. Amazon basic is perfect size .. neither too small nor too big (it looks huge in pics but actually is small)
2) Charging time: This is why you buy a car charger ... Amazonbasic is 2.1 amp vs griffin which is 1 amp... Amazonbasic charger charges phone twice as fast griffin. I use iphone 4 and it gets fully charged (from 10% battery) while i m listening to music in an hr
3) Quality: Griffin use to get very hot (and even my phone use to get hot) after 1 hr of charging ... amazon car charger is of much better quality ... I have used it all day and neither charger nor phones get hot
Overall I would highly recommend this product if u have a iphone (or any smart phone). Whether...Read more

Smart phones and tablets have two charging modes: USB and AC. The mode the phone uses depends on what it thinks is charging it. If it thinks it is connected to a dumb charger it will go into AC mode and ask for as much current as it needs. If it thinks it is connected to a computer it goes into USB mode and asks for 500 mA because that is what the USB bus on most computers is capable of providing. Because of this, USB charge mode charges much more slowly than AC mode and on some devices that need a large amount of current (like iPads) USB mode might not charge your device at all (the device will still be receiving charge, just not enough, so it will lose battery, just at a slower pace).
When I hooked my phone into this charger it went into USB charge mode (500 mA) even though the charger is rated at 2.1 Amps (it is 2 Amps max shared between the two ports but I have not checked to see if that means 1 Amp per port, or if only one port is connected that single port can use the...Read more

Bulky, Cheap Looking, but Functional,

Customer review from the Amazon Vine™ Program (What's this?)
I've been using a now unavailable Kensington PowerBolt as my car charger, mainly for my iPhone 4, but occasionally to reanimate my iPad 2. A single USB socket is fine for commuting, but on long car trips when my car is filled with children and gadgets, a double socket makes for a lot less futzing.
I tested this by charging my iPhone 4 while in use, while simultaneously charging a Kindle Fire and it seems to work fine. On my 40 minute commute, I can add about 20% to the charge status of the Kindle while topping of the iPhone, all without any overheating or fuses popping. A couple years ago, I went through many chargers trying to find one that could reliably power an active iPhone, so I'm glad that cool running chargers have become so inexpensive even while powering two devices.
Devices I've tested and found to work:
iPhone 4
iPhone 4S
iPod Touch 3rd Generation
Kindle Fire
Kodak Playful pocket video camera
Sony Bloggie Touch camera...Read more
