How We Perfect
the Portable Charger

A 10,000-Hour Process

Industrial Design - Understated Complexity

To you, your portable charger is an everyday piece of tech for that pesky low phone battery. To us, your portable charger is the fruit of thousands of hours of labor. Our industrial designers spent months developing Anker's Power series. Countless combinations of shapes, sizes and materials were examined. Now we're able to provide you with the safest, most compact and most durable portable charger in the world. What you should take for granted, we uphold as our guarantee to each and every customer.

Not All Batteries Are Created Equal

At the heart of every portable charger is its battery. In order to deliver industry-leading charging performance, battery power and efficiency must be maximized. The Anker PowerCore series use only the highest grade lithium-ion cells in the world. And to ensure your Anker portable charger keeps going and going, the battery cells undergo a full year of longevity testing before they are ready to go inside our chargers.

The Most Intelligent Microchips

If the battery is the heart of a portable charger, the microchip is the brain. These tiny but powerful chips communicate with their counterparts inside your mobile device to enable adaptable and dynamic charging. As is the case with our battery cells, the microchips we use are the most advanced in the world and have a fail rate of less than 1 in 500,000. That's around 50 times more reliable than regular chip components.

Our Industry-Leading Technology

Our engineers spend up to 200 hours optimizing the fusion of battery cells and electrical circuitry to enable the fastest and smartest charging performance. You don't need to know the technologies behind PowerIQ, VoltageBoost and MultiProtect; you just need to know that with an Anker charger, your device will always be charged as quickly and safely as possible.

PowerIQ®

Detects your device. Delivers the fastest charge.

VoltageBoost™

Maintains the fastest speed, whatever cable you use.

Qualcomm® Quick Charge™ 2.0

Charges compatible devices up to 75% faster.

Our Industry-Leading Technology

MultiProtect™
These chips also provide a layer of advanced safety features, which together form our unique MultiProtect™ safety system. It's like a powerful immune system that protects not just the charger itself, but also your device, your cable, and — most importantly — you.

The Most Comprehensive Testing

During production, our chargers must pass an exhaustive list of tests before they can leave the factory. The series of tests cover around twenty potential hazards, from fire to friction, humidity, and more. Our world-class quality control team spends hundreds of hours thoroughly examining each and every product to make sure the product you receive works every time and lasts a long time.

Temperature - Endures over 143 hours of extreme temperature testing

Shock - Vibrated in all directions for a total of 9 hours

USB Ports - Plugged and unplugged 5,000 times

Impact - Struck repeatedly with an 18-ounce steel ball from over 4 feet

Full Safety Approval

With the tests complete, we make sure our chargers have all the safety certifications required. We even obtain certificates not usually seen on products like these — including the U.S. Department of Energy's highest energy efficiency rating — all to ensure maximum safety, reliability and peace of mind.

Signed, Sealed, Delivered

At last the charger is ready to package. This too takes time to get right. We spend hours testing each type of packaging against impacts, vibration and extreme temperatures. If both product and packaging come through completely unscathed, then we seal it up and send your Anker charger to you.
