4.0 out of 5 stars Initial reaction – positive, 13 Jan. 2014
Verified Purchase(What is this?)
This review is from: Anker 2nd Gen Astro3 12800mAh 3-Port (4A Output) Portable Charger External Battery Power Bank with PowerIQ Technology for iPhone, iPad, Samsung, Nexus and More (Black) (Electronics)
Only had this for 48 hours but immediate response is very positive. It appears robust and well designed. It arrived about 80% charged and from that was able to charge both my iPhone 4 and my iPad, although neither were completely discharged to start with. The device doesn’t really need a shake to fire up, just moving it slightly lights up the LED, but the instructions say that this does not use any appreciable charge, so no worries.

My phone charged quickly, however the iPad took longer. I bought this so that if my iPad ran down on a long journey I could recharge it on the go. However, if you continue to use it with the device connected, the iPad charge level does not increase – but it doesn't seem to decrease either, so perhaps the answer is not to allow the iPad’s charge to get too low before connecting the Astro3.

I imagine a scenario of charging the device overnight ready for the following day’s use. This is feasible using a charging device with sufficient power (9 hours is the estimate). The LED pulses during recharging, and can light up a darkened room quite impressively, so if the LED bothers you in a hotel room at night, the answer would seem to be to turn the device face down.

I am still getting my head round the difference between the three USB sockets. I used the smart socket for both the phone and the iPad, with perfect results. I guess when charging both at the same time I will use the smart socket for the iPad and one of the others for my phone.

The package contained the Astro3, instructions, a nice drawstring travel pouch and a natty little dual purpose cable. The cable is used both for recharging the iPad / iPhone and then, by removing the micro USB to 30pin adapter, to charge the Astro3 from the mains charger. The adapter is quite small so care needs to be taken not to lose it. The cable is quite short, which is good from the point of view that it doesn’t take up much space in the travel pouch, on the other hand when plugged into a mains charger, it doesn’t stretch very far at all. Probably best to consider buying supplementary cables, particularly if planning to charge two things from the Astro3 at the same time.
