The A-Series was designed to take your phone further, so your phone can take you further. Durable enough to go with you anywhere, and stylish enough that you'll want to take it with you. Made with premium components and super-high-density lithium-ion cells for reliable performance in a compact, lightweight product. 
The A-Series External Battery from Zendure is the worry-free answer to a busy life, keeping your phone charged wherever your travels take you--throughout the office, across campus, downtown or around the world.
Durable and Stylish
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.
