Best MacBook Power Bank – Anker Astro E7

Anker Astro E7(Edit: This Power Bank only works with the 12″ MacBook, if you have a 13″ MacBook check out this article)

I picked up the Anker Astro E7 so I wouldhave a reliable charger with me on the long plane ride back to North Carolina from Southern California. I can’t go long without something to help me block out the noise on a flight, and my Kindle and phone are both notorious for dying out on me about four hours into a trip. This trip was scheduled for 11 long hours with two connections, and I couldn’t bear the idea of listening to strangers talk or babies cry for that long.

I have an iPod, a Kindle Fire and a iPhone 6, so I needed a charger that could handle all sorts of setups. I had noticed other chargers I had tried in the past worked great for one device but didn’t charge the others quickly at all. Even when the charge cords looked the same, such as with my Kindle and Galaxy, the charge for one device took much longer than the other. So, I looked specifically for a charger that is built to be universal. The Anker Astro E7 lives up to its reputation as a real universal battery pack.Anker Astro E7 Power IQ

The Astro E7 is so successful thanks to its PowerIQ charging technology. It’s a feature I didn’t know I needed, but now I can’t travel without it. The Power IQ technology isolates each of the battery charger’s three ports and uses an enclosed chip to determine what device you have plugged into it. Then, it sets the charge to match the maximum charging speed your device can handle without causing damage to it. This makes it perfectly usable with the new MacBook and with the PowerIQ I don’t have to be afraid to call it the best macbook power bank since it offers the highest possible current compared to other power banks.

 

Anker Astro E7 PowerAnother helpful feature is the power monitor on the battery pack itself. At a glance, you can tell by the blue LED lights on the pack how much of the charger’s life is left. The charger uses a lithium battery, so I expect to use it for all of its promised 500 recharges (and hopefully more). As much as I use my Kindle and phone, I’m happy I’ve chosen such a long-life charger.

Of course, the lithium battery means you have to recharge the charger periodically. You can use the USB to micro-USB charging cable connected to a desktop or laptop computer, although I learned that method takes a couple of days to fully charge the battery. The instruction booklet suggests using the wall charger instead, and I’ll do that from now on. Luckily, the effiiency of the battery seems to be getting better each time I charge it, which is a sharp contrast to the other battery packs I used before.

During my flight to North Carolina, I charged my Kindle and had plenty of battery left over to charge my iPod and phone. I forgot to charge my Kindle before I left for my return trip, and the charger still had enough juice to keep me wrapped up in my book for the entire six-hour flight home. As you might expect, plugging in more than one device at a time does limit the charging speed for each one, but overall the convenience of charging them at the same time outweighed the need for speed in my case.

The Anker Astro E7 Makes Staying Connected on Travel Easy

Anker Astro E7 iPadI did discover one feature on the Anker Astro E7 purely by accident: It has a built-in LED emergency flashlight connected to its power button. Of course, I figured this out when I was holding the battery pack up to put it into my bag. I accidentally held the power switch for two or three seconds and lit up my neighbor’s face – oops! At least I know the feature is there and that it works really well.

Overall, I highly recommend the Anker Astro E7 for anyone who uses their tablet, phone or other portable electronic devices with any sort of regularity. I’ve started carrying it in my handbag in its net carrying bag for emergencies and charge it whenever the LED indicator lights show the power is less than 25 percent. I imagine this battery charger is a great addition for parents and road warriors alike – anyone who has to maintain several devices at once can use this battery pack to keep themselves wired.

    I just bought Anker Astro E4 with IQ and doesn’t charge my new MacBook 2015 only mantains the charge. Do you think could be the cable USB-C to USB-A 3.1?? Please Joshua let me know your opinion. Thanks

      Hey, this one is the E7 not the E4. The E7 has a slightly higher AMP output so that will definitely help. For me the E7 charges my macbook when its at 50% brightness. If I crank it too high it will just keep the charge however Ive had great success using this http://maccrunch.com/chug-plug-macbook-retina-power-bank-review/ power bank and it charged up my macbook as fast as on a normal power outlet

        were you using a regular usb to usb-c cord? I can’t figure out how to charge with my anker just using the usb-c cable by itself.
