Hi all,
I have a lot of external battery packs. If you're familiar with Anker or even follow them on social media, you'll know they recently had a sale on their new chargers. I was able to get the 15600 and 20100 units for half price. They previously offered Power Users the 10400 unit for .99 which I gladly accepted. This review is in no way an obligation to these deals, but I wanted to share my impressions of these. Mostly, this will serve to compare to some of their other (older) products.
My favorite external battery charger to date is the Anker 2nd Gen Astro E5 16000. It's long and slim and fits in my front pants pocket really nicely. It's got a fabulous piano black plastic chassis, and blue indicator LEDs.
The PowerCore chargers all have a soft matte finish that slightly more of a charcoal black. The matte finish is advertised to not leave fingerprints or smudges, but I can assure you, it does pick up the oils off of your fingers. It does have a better grip than the glossy finished units.
A look at the specifications states that the new units have 4.8A output current, which is up from the 3A max that the Astro was capable of. This is awesome if you need to charge two devices simultaneously. I have a Legion USB Multimeter that I can verify that with but haven't done so yet. These chargers also boast PowerIQ tech, which is supposed to deliver the best charge type for your device. There's also protection and VoltageBoost features.
I've always admired Anker's relatively simplistic packaging and graphics design. They certainly do a nice job making you feel comfortable with your purchase decision, with reassurance that if you're not happy, they will make things right. I haven't had a negative experience yet.
Each unit includes a mesh carry bag and a USB cable (3' I think). The 10400's carry bag is a nice fit, but I think the bag included with the 15600 and 20100 is a bit too large for the size of the charger. I imagine this bag was sized to one of the larger chargers and they haven't updated the bags for the new product. I LOVE how perfect the bag fit is for the Astro 16000.
The USB cables are a great inclusion, although I wish they would include their heavier duty 28 / 21 AWG cables that you can purchase separately. I've noticed HUGE charging speed improvements using those heavier cables, especially with the longer lengths. Another point would be that if you're using these chargers with Apple devices (or anything other than Micro USB), you're going to have to source your own cable.
Charging the batteries is a matter of reversing a USB and plugging it into a charger just as you would your phone. LEDs light up with one LED flashing to indicate charge level.
Now, one difference I should point out compared to the Astro is that when these finish charging, ALL LEDs turn off. On the Astro, all LEDs stay on when the unit is fully charged. I prefer the Astro's behavior so you can see it is done charging at quick glance.
Since I've had the PowerCore 10400 longer, I've actually been using it since I got it. It performs just as you'd expect. That said, I find the wider design harder to keep in my pocket. I like the longer narrow build better.
And on size, the PowerCore 15600 and 20100 units appear to be exactly the same. The specifications say that the 15600 should weigh 341g, but according to my non-scientific OXO scale, both weigh 356g, which is what the specs say for the 20100. And the two being exactly the same size, I can't really tell them apart from each other without reading the very fine print labeling. This could be a problem of sorts should I keep them both around... I could easily grab the wrong one. Now, I'm only trading off maybe 2 charges for my Galaxy S6, but I do like to know what I am carrying. Also for reference, that Astro weighs in at 308g, so it is lighter, smaller, and has more capacity than the PowerCore 15600. I'll certainly use these newer units, but that Astro might remain my favorite.
