There are durable batteries on the market that look like tanks. There are also some very attractive batteries that can't really keep up with a life in motion. The A-Series achieves both toughness and beauty rather than sacrificing one for the other.
The ABS/PC composite exterior is highly impact resistant, especially with the support ridges that run along the surface. A rubber shock absorption belt is fused to the middle to protect against drops. The team even took an early prototype back to the finishing lab to request a more durable exterior coating, so the "paint job" would be more resilient.

Even Smarter Than It Looks

A-Series Portable Chargers include ZEN+ technology, which automatically determines the best charging power to deliver to whatever device you connect to it. It even turns itself on automatically when you connect most compatible devices.
Charge-Through capability, built into every Zendure A-Series battery, allows you to charge the A-Series from a power source while also using the A-Series to charge another device (2A power supply recommended). So at the end of a long day, you only need one power supply to recharge your phone and your A-Series.

Long-Term Standby

A-Series Portable Chargers hold up to 95% of their charge after six months without use, making them ideal emergency power supplies ready to hit the ground running.

Ready for Takeoff

The A-Series is safe to take on board a passenger airplane as a carry-on item. In fact, Titan Airways uses A-Series Portable Chargers to power their pilots' electronic flight bags.

18 Month Warranty

The A-Series is guaranteed to be free of defects when purchased from an authorized seller. Within 18 months of the date of purchase, a free replacement for a malfunctioning product will be provided.

Designed Around the User

The A-Series is designed around the idea that the user should get everything they expect from a product, and then some. After a great deal of research, the ideal feature set was developed, and a product was designed around this feature set.

High-density power cells inside the battery provide a great deal of charge capacity in a relatively lightweight and compact frame. The charge-through feature allows the user to charge the battery while also using the battery to charge another device (2 amp charger recommended). Reliable long-term standby performance means your A-Series will be ready to use in an emergency.

Now sold in dozens of countries with thousands of satisfied customers, the Zendure A-Series is a testament to what can be achieved when a product is built around the people who will use it.

About the Startup

Describe your product in 3 words.

Everyday life saver.

How did you come up with the idea for this product?

With each passing day, phones are becoming capable of doing more and more incredible things. There's GPS navigation, games with incredible graphics, and even the ability to broadcast live video to social media. These things all consume a lot of battery life, but when you buy a phone, you want to be able to explore all of its capabilities without having to keep it plugged into the wall. A portable charger like the A-Series lets you actually use the phone that you paid for. And once we started doing our initial research, we realized we could deliver something that was better than what everyone else was offering.

What makes your product special?

We did a lot of research on the market and on the types of people who often buy backup batteries for their phones. We interviewed them and learned a lot about how current offerings didn't really live up to consumer expectations. There were issues with durability, products that were too bulky, products that you couldn't use and charge at the same time, things like that. So we figured we'd give people exactly what they wanted. And it's very reassuring to see the overwhelmingly positive response our batteries have received, because it lets us know that we've succeeded in doing that.

What has been the best part of your startup experience?

It's absolutely the people. We talk with our customers pretty much every day, and we love hearing what they think of our products. We started this company with very big ideas and very few resources, and hearing from people who have benefited from our products makes us feel that we're really making a difference.
