Anker Powercore 20100 DEALS

Whether you are traveling, running errands, or just doing your normal routine, having a power bank in your bag is a must. There is nothing like having a dead phone when you need it most. In today’s market, there is an endless amount of backup batteries but none are the same. There are a few with more power, more ports, that are conveniently wallet-sized.

Anker has made a name for itself as one of the most popular companies to produce portable chargers. The Anker PowerCore 20100 happens to be one of its best-sellers but is it the right one for you? It’s not necessarily pocket-sized but still travel-friendly since it’s not as big as others on the market.

Anker has an iconic design; a simple black, smooth aluminum exterior. And the company kept the consistent design with the Anker PowerCore 20100 as well. It measures 7.4 x 2.6 x 0.9 inches and weighs 15.2 ounces. The size and weight are larger than other competitors. It’s not that heavy where it will weigh down your bag but it definitely does not belong in your back pocket.

With its sleek and simple exterior, there is not much on the sides of the charger. On one of the rounded edges, you will find the power button and once it is pressed, four lights appear on the top side. These lights let you know how much charge is left so once there are two lights, there is about 50% left.

On the other end of the PowerCore 20100, there are two USB ports along with a micro USB slot to charge the charger itself. The PowerCore 20100 supports simultaneous charging, so you can charge your other devices while charging the charger. There is also a version that has a USB-C slot but that is more expensive. Although, the USB-C port on this charger has the ability to power devices like a MacBook.


So how long does it take for the PowerCore 20100 to charge a smartphone? If you’re looking at an iPhone, it takes about two hours. This is when you are charging from dead batter to a full charge. Phones tend to charge faster if you choose a power bank with the Qualcomm QuickCharge 3 system and have a device compatible. This system is not available for all Anker chargers so it is worth looking into.

The battery inside the PowerCore 20100 has the strength of 20,100mAh. From an iPhone’s battery life, it can recharge the phone up to seven times before it dies. Once it’s time to charge the charger, it can take around 10 hours. Not ideal since it is a long time but Anker claimed that lower amp charging cables can make the charger take longer.

The Anker PowerCore 20100 is quite compact and the amount of power it has, it is impressive of what it can do with 20,100mAh. It can charge tablets several times, power a MacBook for an extra few hours, and still charge itself while fueling other devices. With its multiple ports and the power it has along with the price, it is extremely reasonable. Another bonus is its size. There might be other portable chargers that are smaller and lighter but with the features the PowerCore 20100 has, the others do not compare. It might not have the pass-through and fast charging but it still is a solid charger.
