World Class service

I ordered the wrong battery. Connecting with the customer service, they made me an outstanding outcome to work on the correct battery for my ultra and made beyond expectations to get the battery i needed. Way to go outbound power
Fedex delivered it. Box was soaked with water, we had heavy rain during this time, i accepted the delivery and battery was well protected and is working great

Many thanks for your customer service beyond expectations
I will be buying from them for all my future expansion of the system
Blessings to you all

It’s great to hear that despite the rain, everything arrived safely and is working as expected. We’ll always be here for any future expansions you have in mind. Thanks for your support, and blessings to you as well!

Great battery.

This is our second battery for this system, having bought the original inverter/battery system. We just had a long power outage and the extra capacity helped us sail through without having to bring in the gas generator to supplement the battery backup.

That’s fantastic to hear, John! Having that extra battery capacity must have made a huge difference during the power outage. It’s great knowing your system handled it so well without needing the gas generator. Thanks for trusting us with your backup power needs—we appreciate your support!

Anker C300x

Purchased to supply supplemental power in an off site location. Hope to use when making short duration trips instead of hauling a full sized (2,000w) power station. Still waiting for weather to subside, as it snowed yesterday (04/01). Any products to change the weather?

Thank you for choosing the Anker C300X! It sounds like the perfect solution for powering your short trips without the heavier gear. We totally understand waiting on the weather – fingers crossed it clears up for you soon. While we haven't mastered weather control yet, we're confident the C300X will be ready when you are. We look forward to hearing how it works for you!
