Top critical review
3.0 out of 5 starsGREAT! But it could be better.
Reviewed in the United States on December 10, 2017
This product gets a 3 star rating because of the hassle involved in determining which Anker PowerCore to buy. Otherwise, this is a 5 star item or as close as you can get to perfection at this time for a 10000mAh pack. After reviewing the multitude of Anker PowerCore power packs available, it looks like you can find one in one of their various engineering evolutionary states. There's a mixture of Qualcomm QC and Anker IQ technologies. And, in general, as the price goes up the better features you get, but you need to look closely. That's why there are only three stars here. What isn't in this model is an input that is compatible with the Qualcomm QC 3.0 spec.
What you need to ask of a power pack:
1 - How long will it take to charge the power pack? Specifically, for the best you can do with this device: Will your USB charger provide the 2A needed for full input power?
AND
2 - What will be the length of operation, both for charging and operating your phone? Does the technology fit, so-to-speak?
The best scheme would be to have the ability to charge the power pack slightly faster than the rate you could use up the power (my opinion). This power pack can't always do that. The input power is 10W while the maximum output power is apparently 24W, or so. Other products in the Anker line, specifically some of the 20000mAh chargers come much closer to the mark by allowing charging (input) form Qualcomm Quick Charge power sources. These are further along on the evolutionary scale, I guess.
In my specific case I am charging/operating a Samsung Note 4 which is compatible with Qualcomm 9V QC charging. I also have USB power sources that will deliver the 2A input current required to fully utilize this power pack. This means I am close to being able to charge the PowerCore at the same rate that I can use its energy. This is OK, but in theory you'd need to buy 3 of these (and have all 3 charged) to keep up with a continuous full demand (24W out / 10W in = 2.4), keeping 2 charging while using one of them. Yes, I know this is beyond the intent of this product, but I'm an engineer and want to define the limits imposed by the situation. This is a very good product, but the specs are somewhat camouflaged.
I recommend this product. It could have been better (faster to charge) if the input was compatible with QC 3.0.
P.S. Later today, after writing this review, I ran across the Anker PowerCore+ 10050 and it looks like Anker has done it. This power pack has a Qualcomm QC 3.0 compatible input. On paper the quoted wattage is slightly less, but this shouldn't be an issue, and it's a little cheaper too. I'm not sure why. Also, on the topic of 'camouflage', please see my comments on Anker's organization of their webpage (below).
