5 out of 5 eggsGreat Power Bank

This review is from: [Upgraded Version & All Smart Ports] Anker 2nd Gen Astro3 12000mAh Power Bank External Battery Charger with PowerIQ Technology for Smartphones and Tablets such as iPhone, Galaxy S5, iPad Air, Mini

Pros: Charges my Galaxy S3 from dead to 100% in under an hour. Charging with a 4A charger which I bought to charge phones and tablets will do the job in about 4hrs. Off of my phone charger, overnight. Considering the capacity, I don't expect any less.

Cons: Supplied with only one cable.

Other Thoughts: I have another brand power bank that can be found here and it was supplied with 2 compact coil cables. I use one of those instead of the supplied cable and It makes a very tidy package for traveling. I asked my daughters if they wanted one too and they declined the offer until they saw how well it works. I had to order myself another. Would I buy again. Yes without a doubt. I have been able to get 4 complete charges on my S3 with about 20% power left.

4 out of 5 eggsGreat Power Bank

This review is from: [Upgraded Version & All Smart Ports] Anker 2nd Gen Astro3 12000mAh Power Bank External Battery Charger with PowerIQ Technology for Smartphones and Tablets such as iPhone, Galaxy S5, iPad Air, Mini

Pros: Lots of power! I was able to charge my iPhone 5s four times from empty to full... and there was still some juice left in the power bank.

Cons: Does not come with an AC plug. To charge the bank, you will need to find a 2.1a AC adapter. A 1.0a adapter will not charge it.

1 out of 5 eggsnot that good

This review is from: [Upgraded Version & All Smart Ports] Anker 2nd Gen Astro3 12000mAh Power Bank External Battery Charger with PowerIQ Technology for Smartphones and Tablets such as iPhone, Galaxy S5, iPad Air, Mini

Pros: 3 smart USB ports.
Newegg RMA service is EXCELLENT!

Cons: not true 12000mAh. I tried it to give my iPad 3 (11560mAh) a full charge but it only got to 70% before it quit.
Takes long time to charge, with the IPAD charger (2.1A).
Bulky and heavy.

Other Thoughts: It is worse than I expected. 3 USB ports is nice, but giving the true capacity is just over 7000mAh I wouldn't expect to charge three smart items at the sametime.
The item is also bulky and heavy. I wouldn't want to bring it for a tour in the city. Then the item is not robust enough for a hiking trip. So what it is good for. To me the circle LED indicator is also a nuisance. A tiny move will turn it on. If it is not 100% full it will goes down light by light (the whole circle contains 10 smaller LEDs) to where the capacity is, and it takes a few seconds to know how much capacity it has left.
I am going to try something else, for this price there are many other better options.

1 out of 5 eggsCharging Takes Too Long

This review is from: [Upgraded Version & All Smart Ports] Anker 2nd Gen Astro3 12000mAh Power Bank External Battery Charger with PowerIQ Technology for Smartphones and Tablets such as iPhone, Galaxy S5, iPad Air, Mini

Pros: Nice Design and convenient.. once this is charged..

Cons: The major concern I have is that - The power bank takes more than 12 hours to charge itself with a 5.1V/2.1A charger (as per the instruction manual it should only take 6 hours). Not sure the one I just bought is a defective unit but the charging time is annoying
