  • Q1: How does the Bluetti subscription work?

    The Bluetti subscription allows you to pay a monthly fee for your AC180 Solar Portable Power Station. You can cancel whenever you like and return your AC180 Solar Portable Power Station with no hidden fees. We send you a shipping label (return costs on us), and you return your AC180 Solar Portable Power Station in the original packaging.
  • Q2: What’s included with the Bluetti subscription?

    The Bluetti subscription includes a brand new or like-new AC180 Solar Portable Power Station (normally a $999 product to purchase) and a warranty for as long as you keep your Bluetti subscription for any issues that may arise, with the exception of user error or gross negligence.
  • Q3: Is this the same as financing or a rent-to-own program?

    This is not a rent-to-own program. When you cancel your Bluetti subscription, you are required to return your AC180 Solar Portable Power Station. The goal of the program is to provide ongoing value through a variety of benefits as well as new future products, not to create more options to buy a AC180 Solar Portable Power Station.
  • Q4: Can I cancel anytime? Are there any hidden fees?

    Yes, you can cancel your Bluetti subscription at any time. No contract, hidden fees, or gotchas. We cover the return shipping label as well.
  • Q5: What if I want to upgrade my BLUETTI AC180?

    This is not a rent-to-own program, as our Bluetti subscription includes flexibility, service components, future upgrade opportunities, and a lifetime warranty. However, you may still contact us if you are interested in purchasing your AC180 Solar Portable Power Station, as we are often able to create an option where a portion of your monthly payments to-date can be applied as a discount against the listing price.
  • Q6: What if the BLUETTIE AC180 is damaged?

    Please contact us as soon as possible. We will work with you to evaluate the cause, and with the exception of intentional, excessive, or grossly negligent damage, we will ship you a new product or component and cover shipping fees in both directions. Depending on the degree of user fault, you may be charged for replacement components, parts, or shipping fees. If you’d like further assistance, feel free to contact us at
  • Q7: How do I track my order status?

    Updates are sent to the email address you used to sign up. This includes: order in review, order approved, tracking number received (at which point you can opt for additional delivery status updates), out for delivery, and order delivered. Text messages are also sent for the initial order request and delivery of your package. If you’d like further assistance, feel free to contact us at
