Anker Astro E5 External Battery – REVIEW

Anker Astro E5 External Battery – REVIEW

So, you’re out and about and your Anker Pocket Ultra Portable Bluetooth Speaker sings it’s last note. Or you look at the battery level on your Moto X is at 30% while you’re out on a hike and there’s nowhere to recharge (not that I would know anything about this). What do you do?

There’s no need to fear! Anker’s A1208 Astro E5 External Battery is here!

The Astro E5 External Battery is 16,000 mAh of raw power! According to Anker, it can charge your iPhone 5S over seven times. Since I don’t have an iPhone, I decided to plug in my JBL Charge Bluetooth speaker that had a red flashing light, which just indicates “battery needs charging.” The Astro E5 indicates its level of charge via four LEDs. If all four LEDs are lit, then it is charged 100%. If three lights are on, but the fourth light is blinking, then it is at 75%-99% of charge. Two lights on and the third blinking, indicates 50%-75% of the charge. First light on and second light blinking is 25%-50% of charge. One solitary light blinking means that there is less than 25% of charge available. Unfortunately, there’s no display to tell you the exact battery status. As you can see by the above photo, my Astro E5 has 100% charge.

The Astro E5 has two “IQ” charging ports that detect the device plugged into it and how much juice is required for that device. The ports have a maximum output of 5V/3A. The input port, for charging the Astro E5 is 5V/2A. There’s also an LED flashlight, which is activated by holding the power button for a few seconds and it turns off in the same manner. The flashlight isn’t very bright, but I suppose it’s better than nothing. It can be used to find that stick of gum at the bottom of your bag.

Well, after I plugged in my JBL Charge, I fell asleep, so I couldn’t tell you exactly how long it took to charge, but I can say that it was less than four hours.

The Astro E5 does come with a micro-USB cable, but it does not come with a power adapter. You can use the adapter that comes with any other USB based charging device, such as your phone or tablet. It also comes with a carrying pouch.

Here’s the techie stuff:

  • Battery capacity:    16000 mAh

  • Input:            5V/2A

  • Output:        5V/3A

  • Size:            5.9” x 2.5” x 0.9”

  • Weight:        10.4 ounces

The power adapter you use to charge the Astro E5 determines the total amount of time needed to charge the adapter:

  • 5V/2A:        8-9 hours

  • 5V/1.5A:    11-12 hours

  • 5V/1A:        16-18 hours

  • 5V/0.5A:    34-36 hours

The Anker A1208 Astro E5 External Battery is currently available in black from Amazon for $39.99 or white for $44.99 (yes, really). If you require a Lightning Cable, you can purchase both the Astro E5 and a cable for $49.99.
