Energizer Black Portable Charger (XP4001) Energizer Black Portable Charger (XP4001)

Pros: High quality device. Feels nice and solid.

Cons: Although it will charge 2 devices, it will NOT charge a single iPad2. My guess is not enough amps. The iPad sees the connection but imediately goes to not charging.

Other Thoughts: Overall a rather nice device as long as you don't need it for a power hungry tablet.

Pros: Has different adapters to fit most devices.

Cons: Arrived DOA

Other Thoughts: Unit was not sealed and was coming apart in the package. Not only did it not have a charge as advertised it would not charge even when plugged in overnight. I bought this on sale so can more easily absorb the loss and have the adapters as a consolation but would recommend purchasing a different unit.

Pros: Works OK with my Android phone, but non-standard charging plug is a big negative. If the charger gets misplaced or broken, the product is worthless. Most other power packs use a standard micro-USB charging plug that can easily be replaced.

Cons: non-standard charging plug

Pros: Charges fast. Bring my Droid from empty to full twice on a single charge. Includes many adapters for different devices.

Cons: I wish it had a percentage display for remaining battery power.

Pros: Feels very solid. Charged my fiance's iPhone 5 pretty quickly and didn't need a recharge.

Cons: The single con I have for this product is huge to me. The product includes several different tips and 2 USB to "tip" cables. It also comes with an AC charger for for the device. While this is good in some ways (faster charging with direct /appropriate voltage), it severely reduces the item's mobility. There are many times when traveling that I don't have access to an AC outlet. A USB charger would have been much more mobile. If I ever take the device on a trip, I have to make sure to bring its proprietary charger along with me or I will only get one charge out of it.

Other Thoughts: Kinda my fault for not looking at the pictures closer, but still.. A poor design choice with a proprietary tip vs a standard usb cable.

It would have made much more sense for the tip cables that come with it to be able to charge the device.

Pros: Keeps a good charge and is straight-forward to use

Cons: Advertised to charge an ipad, but does not charge with my ipad3. Pretty much unless for me since this is why i purchased it to begin with.

Pros: I purchased a Google Offers deal for this, as I was planning on buying one anyway. I could not believe that it was $18.00! I thought that this must be some sort of cheap imitation of the one I was going to initially purchase, but why not give it a shot for that cheap? When this arrived in the mail, of course I tried it immediately. What an amazing product! My phone was nearly dead and although I was at home, I decided to put this to the test! My phone was fully charged in about the same amount of time that it takes for my wall adapter to do the same thing! I was impressed! It comes with more attachments than I even know what to do with, and a carrying case (because my phone dies so quickly, I will be leaving this in my purse at all times). I highly recommend this.

Cons: Other than the fact that I had to wait for it to arrive to use it, there really are not as of yet.

Pros: Great that it can charge 2 phones and many types of phones at once

Cons: Much bigger than other portable chargers. The brookstone one clips right into the bottom and is easier to use.

Pros: Comes with 6 different proprietary connectors for different phones (LG, Samsung, Nokia, Apple, etc.)
Easy to charge and comes with carrying bag.
Two USB output ports.

Cons: Haven't owned this product long enough to find anything wrong with the performance so far;
HOWEVER, when I unboxed the product, it was missing the Apple connector, the plastic wrapping was extremely crinkled, and there were small scratches on the back side of the battery pack.
I am convinced that I was sent a used/refurb product. Not cool.

Pros: Have to love the dual charging ability. Unit also let's you quickly check whether it's full or needs to be recharged. Although it does come with a lot of tips; the options are almost mute since you can just plug anything into the usb output. The unit definitely has a little weight to it and makes it feel very solid. The unit has 2 usb outputs both can be used to charge your everyday smartphones while only one can charge your more power hungry tablets. The wording is pretty clear so keep an eye out.

Cons: The only con is that it requires a smaller input to charge the unit; which if lost can be a hassle to go purchase a replacement. It should have been a micro usb which is much easier to replace.
