5 out of 5 eggsExceeded Expectations

Pros: Appears to be very robust construction. Well fitted assembly. No mismatched edges snagging on pockets or bags. Narrow design lets it fit in a cup-holder in a car...don't have to worry about it flopping around while in use.

Rounded corners mean it doesn't snag inside pockets or carry bags, and won't poke holes in the material...unlike sharp-cornered units.

Appears to execute a Power-On-Self-Test, which is not specified but good to have. Many "power banks" do not.

Power button is recessed. Good design choice..
USBout port and USBin port also recessed. Will help avoid damage and accidental shorts. Further reducing chance of shorts, the unit turns itself off after about 8 seconds if nothing is connected to the cable.

Has charged every tablet and phone connected to it (some needed a different cable).

Aesthetics: Looks nice. Blue LEDs not overwhelming.

Cons: None so far

Other Thoughts: Well worth the on-sale price I paid. Will likely buy as gifts if no problems in next few months.

Personally, I believe in redundancy when it comes to portable electronics, so I plan to use 2 of these instead of 1 larger capacity "power bank". Bonus is that 2 of these (on sale) cost less than a single equivalent total capacity unit (also on sale). Also, having 2 units provides flexibility to recharge one while the other is carried around, and if one fails I still have another portable bank immediately available.

3 out of 5 eggsNot compatible with all phones and devices

Pros: The big battery in a smaller package is nice. It does have a little more weight than others but the protection circuitry should be worth the extra weight.

Cons: I received one and it was bad out of the box. The second one I received works well, just not compatible with the Galaxy s5. I have used several portable chargers and they work well with my phone, this one is a no go with the s5

1 out of 5 eggsdid not work after initial charge

Pros: none seeing as it doesn't work

Cons: does not charge anything for more than 5 seconds before shutting down

Other Thoughts: I usually trust offers from newegg, but this is just awful. I charged it for about 5 hours and initially tried to use it only to find it does not remain on

5 out of 5 eggsWorks well and fast

Pros: I plugged this into my phone, which was at 55% charge. The phone was 100% charged when I checked it 90 minutes later. This is faster than charging the phone with the included charger. The Power Bank is still showing fully charged so it's now charging a camera battery. This is the power bank I'm going to carry with me.

Cons: None

Other Thoughts: This is my second power bank. The other one was from another manufacturer and was very disappointing. This Mediasonic Power Bank does a good job and I'm completely satisfied with it.
