LOVE!

We ordered this a few months back and had a little issue with shipping (NOT bluetti's fault, but rather the package was lost or stolen in route to us and never made it to our local facility) and a new unit was sent out to us! We have actually been using it to power our chick incubator and our baby chick brooder heat pads and it's been pretty awesome! We have had the threat of power outages due to living in the gulf coast with major severe thunderstorms lately and am SO thankful we got this system in time! We plan on adding 3 more batteries and potentially another unit to allow us to have more of our home using solar! So glad we got this!

B300 Is Very Well Designed

After extensive research I eagerly bought the 2*AC300 + 4*B300 + 6*PV200 + P030A bundle when it first became available. Bluetti and early purchasers like me were caught by surprise when an initial batch of delivered B300 battery modules unexpectedly arrived damaged from the rough handling of shippers. Upon discovery of this problem, Bluetti responded quickly to temporarily halt deliveries, to reinforce newly manufactured battery modules and shipping containers, and to replace all the damaged B300s as soon as possible. In addition to receiving new, strengthened versions of the B300, each purchaser (who initially received a damaged B300) also now received an AC20 portable solar generator that Bluetti generously gifted. (Thank you, Bluetti!)

Through the duration of this purchasing experience I received excellent customer service from Bluetti. My Bluetti representative, named Icy, was very responsive, courteously answered my questions, diligently kept me informed, and successfully managed the entire process to have everything I purchased eventually delivered to me in perfect working condition. The B300 itself is very well designed and functions perfectly, balancing large capacity with portability, expandability, and connectivity. In addition to serving as the AC300’s connected storage component for power, the B300 can operate independently, able to be separately recharged from multiple sources and output DC power through several standard ports. I highly recommend Bluetti and their B300 battery module to anyone wanting a trusted source for well built, reliable, technologically advanced, portable power stations and solar generators.

Couldn't be more happy!

I recently bought the AC300 + 2*B300 bundle from Bluetti. It took 3 months to receive it, but that was ok because it was worth the wait. When my long-awaited bundle arrived, I excitedly opened the boxes and began setting the system up. My excitement somewhat wained when I discovered that one of the B300 batteries was apparently defective. To make a long story short, as they say, I contacted the Bluetti service department. Max was my service rep. And, after a few emails, back and forth, he felt more like a friend. Max guided me through a number of things he wanted me to try to see if it would resolve the issue with the battery. After a number of pictures to help him "see" what he was dealing with, he finally wrote me saying, "Thanks for your patience. We'll send you a replacement B300 asap."

I was happy with the way my situation was handled but, to not be outdone, Max also informed me that they were sending me an AC20 for compensation for my time and inconvenience. Eight days later, the AC20 and my replacement battery arrived at my home.

I so appreciate the way Bluetti handled my battery problem. I had heard that Bluetti's service techs were fantastic . . . now I'm a believer. I'm blown away at how painless AND friendly my "problem" was handled. Their generosity, with the AC20, is overwhelming and demonstrates that Bluetti cares about its customers. Trust me, my friends and cohorts will be hearing about your great products and phenomenal customer service. Thanks, Max!

Great product and exceptional service

The customer contact and communication during the extended delivery process with Bluetti has been excellent. The customer service representative, Icy, has handled all the communication in an orderly, professional, and courteous manner. Icy was prompt to resolve payment, delivery, and technical questions that I had in a competent and concise manner. While the AC300 + 2*B300 + 3*PV200 bundle purchased is a new product and the product technical information is yet to be published, Icy did a great job answering all my equipment operational questions.

Technically, the product functions as described so far, and has the features as described in the website. I am very pleased to have made this purchase, and would recommend Bluetti Power without reservation.
