Well, all the power you will ever need until it needs to be recharged again.
What is it?
The Anker PowerCore+ 20100 is a USB-C portable external battery containing a massive 20100 mAH battery.
This particular portable battery is host to 2 x USB type A ports and 1 x USB type C ports. Charging the battery is completed via the USB type C port which is also capable of delivering a charge to USB type C devices, including the new MacBooks which charge via USB-C. While the USB type A ports are for charging other devices such as your tablet or phone.
The PowerCore+ 20100 utilizes “PowerIQ & VoltageBoost” technology. According to Anker, ” PowerIQ™ technology dynamically detects and adapts to your device’s unique charging protocol enabling it to charge at full speed. So thanks to PowerIQ™, together with Anker’s industry-leading power output, charge faster and save time.” (source https://www.anker.com/poweriq/). What does that mean? Simply put, your device will charge faster when connected to this battery pack compared to most other charging appliances available.
In the box you will find the following: 60cm USB A to USB-C cable, 60cm Micro USB cable, 90cm USB-C to USB-C cable, welcome guide and a travel pouch. The PowerCore+ 20100 comes with an 18 month limited warranty as well.
Why do you want this?
This is a road-warriors best friend. With the exceptionally high capacity battery, this power pack is capable of charging devices such as Google’s Nexus 6P’s 3,450 mAH battery several times before needing a recharge.
According to Anker, you could charge one MacBook, one iPad Air 2 and one iPhone fully on one charge.
This would be ideal for use on a weekend trip for business or family camping trip and want to keep your phone and tablet charged up without lugging around several different wall wart adapters and cables.
I recently used the PoweCore+ on an trip to Montreal. I had no qualms about where I would be able to plug into a traditional charger. We were staying in an Air BNB apartment, so plugging in each night was not going to be an issue.
However, we were planning to be sightseeing each day of our 4 days in the city and I do not trust my Nexus 6P to make it through a day even when the camera is not used. So with the extra drain expected on the battery, I did not want to worry about missing a picture as the result of a dead phone battery.
The PowerCore+ added very little bulk to my bag that was also toting our water bottles among other essentials.
While out and about snapping pictures my battery quickly dropped down to the 40% mark. Between destinations I connected the USB A to C cable to the battery pack and carried on for 20 or so minutes. Each time I disconnected my battery was back up to about 75% and I was ready to go again.
One thing I did not discover until after my trip was how to use the battery with a USB C cable to charge the device. As mentioned this battery can charge a device off of all three USB ports. Each and every time I connected my Nexus 6P to the battery pack it would draw power from the phone, not provide a charge. After some reading online I discovered that to charge a device off the UCB C port, you must first press the indicator button on the battery then connect the device. This appears to reverse the current direction on the port allowing it to charge your device.
Should You Buy This?
Absolutely! There are several other brands in the heavily saturated market of portable batteries but, Anker is number one in this space, so you know your investment will be well worth it in the end.
