I've just taken delivery of one of these. It's a hefty best isn't it? Seems noticeably heavier than my Anker PowerCore+ 2600. Maybe that's down to the different chemistry. I'm not complaining, anything too light makes me suspicious about the specs. And you don't buy a power bank like this to put in your pocket.
Haven't had a chance to do many tests yet, other than it is charging at the 2A it says it can take.
I can't believe what a bargain this is. I wouldn't be surprised if the price went up once it has some good reviews. I'm tempted to buy a second one now even though I don't need it.

Hi
Have you tested yours yet?
Just got mine on Friday
Charged it up to Max, it came at 89%.
Pleased it went to 100% and then cut off itself. It did get the samsung 2.0A charger pretty warm doing so :-/
Charging an iPad Air it was reading 4.67V and 1.32A,
Conversely, when I charged the same iPad Air with a 2.1A Apple charger, it read 5.01V and 2.02As
I was surprised, that this battery; with an alleged output of 3.1A couldn't at least equal what the Apple charger did?
I then charged an iPhone 7 Plus, that came with a 1.0A charger and the Tqka charged the phone at 4.91V and 0.53A. As that seemed low; I tried it with the Apple charger, which is rated at 1.0A, and that charged the phone at 5.02V and 0.98As ... more like it.
The phone test is the nearest I could get to testing something with the same power consumption as my camera namely 5V 1A.
Is it normal that these battery packs underperform. Just testing the Battery without a load connected, at 100% charge, registered 5.01V but once it dropped to 98% charged, the battery read 4.94V.
I wonder if it only outputs 4.67V and 0.53A would that be enough juice to run my camera ?
OK those are the worst of both volts and amps. But even at say 4.91V and 0.53A ( as I experienced with the phone ) would this battery run the camera smoothly.
I can’t test it until my new 4 meter USB cable arrives, should be soon, so I will know then.
Is this normal with these batteries? i.e. to run under spec?
Or have I got a dud.
- Slightly concerned as this is at 100% full charge will it drop lower as the battery depletes?
Zero support from TQKA, there is no email support contact address, only a UK Mobile that they never answer and it just goes straight into voicemail.
Ha ha for the 18month warranty!
Just wondering should I return this and get a RAV Power .. Lithium Polymer battery?
Not as good as the LFePo4 this is supposed to have, but... . Interestingly it does not state this on the battery or on the box or the tiny manual in its specification.
I find that a tad disturbing ... hey if you have a great feature print it everywhere eh? not just on the (soon to disapear forever) Amazon sales info list. :-/
Call me suspicious but it all smells a tad wiffy !
