General Questions About the Bluetti Solar Generators

Q: How long will it take to get to my door?

  • A: Once your order has been placed, expect about 10-15 days to have your package delivered to you.

Q: Where are the units coming from?

  • A: We work directly with MaxOak cutting out all the middle men in the process.  Your Bluetti is coming directly from the factory, fresh off the factory floor.  We try to minimize the number of people that touch your Bluetti before you do.

      Q: What if I dont want my Bluetti anymore?

      • A: We understand that situations change, and you might have no need for your generator anymore.  If you are within 5-7 business days (or before the unit has started shipping) of ordering your Bluetti, you can cancel no questions asked.  If your Bluetti has already started shipping you will be charged a restocking fee / return shipping fee.
      Q: What comes with the Bluetti?
      • A: The Bluetti comes with the Bluetti solar generator, the AC power cord, MC4 adapters, information booklet & warranty slips.

      • A: Due to shipping regulations, the Bluetti is only allowed to be shipped partially charged. Make sure you fully charge the Bluetti after it is received.
      Q: What is the warranty on the Bluetti?
      • A: The Bluetti comes with a standard two-year limited warranty.

      Q: What happens if my Bluetti isnt working?

      • A: In the unlikely event that your Bluetti isnt working properly, we will help you fix it or we will replace it!  We will need a video of the problem you are having.  Since we work directly with MaxOak, we will have MaxOak engineers analyze the issues.  If it is easy to repair, we will help you repair the issue.  If it is a bigger issue than that, we will get your product returned and ship you a new one.  
      Q: How many watts can the Bluetti handle?
      • A: The Bluetti had a 1000 watt pure sine wave inverter that can surge to 1,200 watts.  - Also, it is important to note that the Bluetti wont register a load that is less than 30 watts.  If you are using something less than 30 watts, you wont see anything on the screen.

        • A: Nope!  You can use DC power without turning on the inverter.
