    Excellent Charger (UPDATE), February 3, 2013
    By 

    This review is from: RAVPower Dual Port 15.5W / 3.1A USB Car Charger for iPhone 6, 5s, 5c, 5, 4s, 4; iPad 5, Air, Mini; iPod Touch, Nano; Samsung Galaxy S5, S4, S3, S2, Galaxy Note 3, 2; Kindle; LG G2; Nexus 5, 7; Motorola Droid RAZR MAXX; Blackberry; Nook Color; Bluetooth Speakers and Headsets; HTC One X V S; External Batteries and More (Black) (Electronics)
    I received this charger a few days ago, and really like it. I used to have a no name micro usb charger for my phone, and it was only 500mah, which for non-techies means that it charges very slowly. This charger charges very fast even on the 1A port. It has 2 ports a 1A, and a 2.1A. I recommend the 2.1 A port for ipads and tablets, and to charge your device a little quicker. If you dont need a very quick charge, the 1A port will still charge most phones in an hour and a half from dead to full.
    UPDATE 3/22: This charger worked well for a little while but quit charging on me today. Lowering my review to 2 stars.
    UPDATE 4/12- RAVpower quickly contacted me after posting my update and sent me a new one at no cost. Back up to 4 stars.

    Customer Video Review Length:: 4:09 Mins

    Please view my video for further information.

    There are a lot of car chargers out there, but what makes this one worth buying?
    1) There are 2 USB ports
    2) Of the two ports, one is 2.1amps, one is 1amp. That means you can charge BOTH an iPad/tablet AND a phone at the same time
    3) Mat black finish is applied where cables are unplugged a lot to keep from scratching. (yes this is just a cosmetic feature, but it makes everyone feel better when there electronics don’t get scratched!)
    4) Replaceable fuse

    This car charger simply does what it states. It will charge any device through USB while your 12V plug on your car is on. It provides users with the ability to use GPS pas in their car without completely draining there battery when they get to their destination

    What would make this product better?
    The only thing I would change is that I would like a switch on the side of each USB port that allowed you to change the power output. The reason is that it would be nice to be able to charge 2 iPads/tablets at once or 2 phones at once. YES you can charge your phone with a 2.1 amp output, but I’m not sure that it’s too good for your battery.

    Would you buy it for a friend/recommend it?
    WITHOUT A DOUBT!! At the price point, one cannot go wrong buying this product. RAVPower makes great products and you should not hesitate to order. Take a look at some of the reviews here; people that have issues got a complimentary replacement. That’s the sign of a true customer oriented company.

    Here are few other product that I highly recommend!:
    RAVPower External Battery Pack 2800 mAh External Battery Charger / Power Bank / Flash Charger With Build-In AC Charger
    RAVPower® 5200mAh Extended Battery for Samsung Galaxy S4, GT-I9500, With NFC/Google Wallet +Dark Blue Cover
    UPcase Waterproof Case for Iphone 5 – IPX8 Certified to 100 Feet

    A compact and sleek car charger that doesn’t compromise price. RAVPower does it again!, March 16, 2014
    By 

    This review is from: RAVPower Dual Port 15.5W / 3.1A USB Car Charger for iPhone 6, 5s, 5c, 5, 4s, 4; iPad 5, Air, Mini; iPod Touch, Nano; Samsung Galaxy S5, S4, S3, S2, Galaxy Note 3, 2; Kindle; LG G2; Nexus 5, 7; Motorola Droid RAZR MAXX; Blackberry; Nook Color; Bluetooth Speakers and Headsets; HTC One X V S; External Batteries and More (Black) (Electronics)
    USB charged devices have been very popular for the last decade. Everything from MP3 Players and mobile phones to mug warmers and multimeters are all powered by USBs. RAVPower has made the RAVPower Dual Port 15.5W 3.1A USB Car Charger for users that want to charge their devices from their vehicle.

    When I first opened the packaging, I realized how small the device really is very small (3.9 x 2.6 x 1.4 inches) and light (1.6 ounces). I figured that this device would be very large, like many other USB car chargers that I have bought, but it isn’t. The device has the push in part at the end of the charger, with two push in balls and black metal to keep the car charger into the cigarette outlet, with a groove and red LED indicator in between the 2.1A and 1A USB ports. The RAVPower name on the side and the text to indicate which USB port is 2.1A and 1A.

    Specifications:
    • Output DC 5V 2A & 5V 1A
    • Input 12-24V 1000mA
    • Size 3.9 x 2.6 x 1.4 inches
    • Weight 1.6 ounces

    When the car charger is plugged in, the LED indicator is on to indicate the USB ports are able to charge devices. The car charger sticks out about 1.5 inches and firmly fits in the cigarette lighter without any issues. I was able to successfully charge my Nexus 7 (2013), running Android 4.2.2, with a 3950mAh battery. The Nexus 7 was able to achieve the following results:

    0.21A
    5.14V
    0.24 Peak A
    4.98 Min V

    The Nexus 7 was able to take 0.21A from the charger, allowing more than 2.9A to be used. Because devices don’t use the full 2.1A, you are able to use both USB ports without compromising your device from charging slower.

    Because of the size and usability, this is a great USB car charger for a quick charge, and is why I recommend this to anyone who needs a cheap USB car charger without compromising quality. I give this product 5 out of 5 stars.

    Pros:
    + Very cheap but that doesn’t compromise quality. RAVPower makes good, durable, products.
    + Devices don’t take much current, which allows two tablets to simultaneously charge.
    + Very small and light. Very compact for a car charger.
    + Choice of two colors (White and black).

    Cons:
    – I have no cons for this device.

    I was supplied a sample in exchange for an honest and thorough review.
