3 Outlet Power Surge Protector Wall Tap w/ 2 Built-In USB Charger - 1050 Joules - Plastic
This charcoal colored, 3-outlet surge protector, with 2 built-in USB charging ports, is a great solution for keeping your 3 outlets protected, while at the same time charging your USB devices without having to purchase separate USB wall chargers.

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.
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.
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.
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.
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)
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!
CONS: ZERO CONS.
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.
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.
PROS: Works with ipod touch 4g iOS5
