Rosewill PB-U2-12000-BK, Plasma-Mini - Black, 12,000 mAh AC Portable Power Bank for Laptops, Smartphones, iPhones, iPads, iPods, PSPs, Etc.

Pros: It will charge anything, including my Asus Transformer TF700 tablet. It can be used as a power source for any device.

Cons: Gets VERY hot.

Overall Review: With the AC outlet, this battery can power or charge anything. It really is like having a portable wall outlet.

Pros: 12,000mAh, the most powerful power bank I have had. It works great and charges any of my devices. My tablet, galaxy 5 and blackberry, not a problem. This product is great for anyone who travels a lot for work or work long days. This little box of power bank saved my life a few times, while I was driving in nowhere, sort of lost. It powered up my phone quickly and I was able to call my friends for directions. Overall, I think this product is reliable and does good job as described.

Cons: N/A

Pros: It worked for one month

Cons: it worked for one month

Overall Review: Unfortunately I did not get a chance to return it or exchange it. Maybe I got a bad product but still, I would not recommend it to anyone.

Pros: Long lasting reliable battery, sleek look, multiple ports and types. Works quickly and charged my equipment fast while keeping the juice flowing throughout my session. Most others died in an hour. This little guy kept pumping for 4-5 and I run it pretty rigid.

Cons: For some it may be bulky, i got over it quick. Aside from that only one gripe for those who need juice now but forgot to charge the beast or ended up using it all and wish to continue while using it. It wont charge your equipment while its being charged through the D/C port. I found a loop hole where you are connecting a male to male end usb appropriately. But this.method charges any device poorly, including the bank. While this does put a big red stop sign to upstart gitter done no breathing room types. For anyone smart enough to plug the thing in proper at night wont have any issue. Otherwise give it like an hour at most and your up and powered for several more.

Overall Review: It came with a universal adapter. wow, Well done Rosewill.

Pros: I find laptops at garage sales, goodwill, and craigslist and it always irritated me when i got a dead laptop. This basically solved all my problems and more. I use this with my universal charger to test any laptop i find and also can test anything else that uses under 80 watts. Go to a garage sale and dont know if that fan works? Plug it in! Comes with a nice sleeve bag and very good quality charging plug. The charger charges this thing within 30 minutes to an hour. I got battery banks smaller then this that charge with micro usb, they take days!

Cons: Loses charge fast. If you leave this setting for about 4-5 days you basically just lost 25-50% of its charge. I am not sure if this is a defect or not but if i charge it before i do my thing i got no issues. Has a 80W limit. I wish this could handle up to 150 watts so i could test speaker systems or even desktops.

Overall Review: The bag that comes included should be bigger, have double sleeve compartments, or just include 2 sleep bags that velcro together or something. Reason being is because the charging plug and its laptop sized power brick do not fit in the same bag.
