    Does not provide maximum charge to Galaxy Nexus
    I own a Galaxy Nexus and I wanted to get additional USB chargers for home so I don't have to lug around the stubby USB charger that came with the phone. Most importantly however is that I needed a dedicated charger because charging through a standard USB port is too slow - they don't provide enough current. Thus, I bought this device (actually 2 of them). It doesn't charge my phone at the maximum speed and I'm really disappointed. I didn't see anything in the description indicating that it wouldn't perform like any other USB charger, which clearly it doesn't.

    So all I can say for sure is that if you're thinking of purchasing this to provide convenient fast-charging of your Galaxy Nexus, then I can positively tell you that this will not meet your need.

    PROS: Since it doesn't actually do what I purchased it for, I can't really give it any pros.

    CONS: When I charge my Galaxy nexus via a standard USB port (e.g. from a computer), the phone indicates it is "USB" charging - which is very slow. When I charge using the USB charging wall adapter that came with the phone instead it indicates it is "AC" charging, and it charges much faster. I expected the USB charger built into this surge protector would also provide this "AC" charging since it can provide 2A. Well, it doesn't - it only performs a trickle charge.

    Ok, so my fault for not reading the specs and trying this in Europe. It failed immediately, but that's my fault. The problem is that it failed spectacularly, emitting sparks and flames, and killing the breaker in my hotel room. For unknown reasons, I tried it again back in the US, and it does the same think.

    The product should fail safe, not fail deadly.

    CONS: Does not work on 220v
    Sparks/flames when plugged in to 220v current, or into 125v after being damaged by 220v.

    Not even close to 2.1Amps
    I bought this unit along with PID - 5459 (10ft USB 2.0 A Male to Micro 5pin Male 28/24AWG Cable w/ Ferrite Core). A combination which would excite me as a user to fast charge my Nexus 5.

    However, after using it for a week or so and trying different combinations between the Original Nexus 5 charger/cable and Monoprice charger/cable, I don't think this unit delivers 2.1A of power. To sum up, I got the following mA with different combinations:

    Monoprice 2.1A adapter + Monoprice Cable = My phone actually discharges slowly at -33mA.

    Monoprice 2.1A adapter + Nexus 5 Cable = I cannot seem to pass 100mA

    Nexus 5 charger (1,2A) + Monoprice Cable = Did not pass above 350mA

    Nexus 5 charger + Nexus 5 cable = I average at 981mA.

    I don't if I have received faulty units but I am not getting the required power.

    PROS: 3 Outlets and 2 USB ports

    CONS: Not enough power to charge. It is suppose to give me 2.1A of power to charge my Nexus 5. It does not even reach a 1.2A powered Nexus 5 Charger.

    USB ports limited to 500mA
    See 7/6/2012 review by Luck from St. John, NB, Canada.
    Despite the 2A rating of the unit, the charger will only deliver 500mA on any one port.
    I tested this with my Galaxy Nexus phone, which will display "Charging (USB)" when fed 500mA or less, and "Charging (AC)" when fed more than 500mA. The same USB "A"-to-micro cable, plugged into the 1A Samsung charger that came with the phone, shows "Charging (AC)", but plugged into either port of the Monoprice 7991 (with nothing else plugged into the 7991), shows "Charging (USB)".
    I bought 3 of these 7991 units. Two of them have had failures just past the 1-year warranty expiration. One unit's top USB port stopped working just the bottom one works. The other unit stopped providing sufficient current to actually charge the phone, on either of its USB ports. The phone says it's charging, but the battery %charged goes down.

    PROS: Inexpensive provides 3 AC outlets and 2 USB ports

    CONS: Covers both outlets of a standard wall outlet USB current limited to 500mA
    Two of 3 units I bought have failed just *outside* the one-year warranty period.

    Nice little device to have in my bag to use while traveling or at cafes. Problem that I have is that the USB ports doesn't provide enough power to charge a Nexus 7. I tried using the tablet plugged in to the charger and it actually slowly discharges. This is while it's the only thing plugged into the charger. I don't have the same problem when using the ASUS charger that came with the Nexus 7. Monoprice needs to update the product specifications because it doesn't seem to output the 2A that it advertises.

    PROS: - Portable
    - Convenient to have both outlets and USB ports in one package

    CONS: - USB ports does not provide enough power
    - Shaped such that it blocked the other outlet (remedied by using a 1ft extension cable)

    Yes! Buy it NOW! Great for travel!
    Buy one of these http://goo.gl/YCxmV with it so you don't take up BOTH outlets on the wall. I travel with both of these items and it makes life in the hotel room SO much easier!

    PROS: Cheap as heck!
    Lightweight & small profile
    TWO usb ports!
    2.0 AMP usb ports! (Great for charging tablet devices at quickest speed possible) -not all usb ports are equal!

    Unlike many other similar devices this will charge an iPhone and iPad simultaneously through the USB ports. Excellent quality and amazing price. Highly recommended.

    Affordable, capable USB wall charger

    PROS: Obviates the need to have your computer or a separate AC adapter charge a USB device. Provides sufficient amperage to charge two devices simultaneously. Small enough for travel.

    CONS: Make sure you have ample space in front of the wall socket, as the device extends at least 3" from the wall, and the USB cables need an inch or two of room on top of that.

    absolutely beautiful, especially for travel
    The first and most important thing is that you buy this without hesitation. The second is you might want to consider more than one. Beyond that, I'll tell you I use it daily when I work from home. It also comes with me on trips. There's a hotel at which I frequently stay. It has loose single outlets on lamp bases. All of my chargers are ungrounded and therefore loose in these outlets. This device fixes that, giving you 3 more grounded outlets and 2 full-power USB ports.

    I like that it charges my iPad, which is picky about its charging current. It simultaneously charges my Android, also with sufficient current. It makes the business of chargers a no-brainer, which is a big help especially on trips. Pack this and the appropriate cables and you're set.

    It's just very handy. Upon purchase I wasn't sure if it was valuable enough to deserve the almost $10 price. It is. It would also make for a great gift.

    PROS: -charges all of my devices

    -power indicator LED

    -3 courtesy outlets

    CONS: The physical design doesn't allow you to plug it in just anywhere. You have to use the lower outlet of a duplex receptacle. It might require a few seconds of extra consideration.
