The following "Return & Refund Policy" applies to Erayak products.

Shipping Cost

The shipping cost for returning the products will be borne by Erayak or the customer in the following situations.


1.When Erayak Pays For Return Shipping


Erayak will pay for the cost of return shipping if the reason for the return was the result of OUR error.

Examples of instances may include:

  • Item arrived defective and cannot be fixed with a replacement part.
  • We shipped out the wrong item.
  • We shipped it to the wrong address.
  • We shipped a duplicate order.
  • Item malfunctioned during the 30-day returns period. (The customer should install and operate the item properly per the product manual instruction.)

Special Case Explanation: In cases where a product has quality issues, users are required to return it to the designated Erayak warehouse in the United States, and Erayak will cover the shipping costs. However, if the user's return address differs from the original shipping address (for example, if the shipping address was within the United States, but the return address is in a remote or international location), resulting in shipping costs that exceed Erayak's initial shipping costs, the user will be responsible for paying the additional shipping fees.

IMPORTANT

  • For items that arrive damaged or are defective, the customer MUST provide videos or photos to support the claim that the item arrived damaged or is malfunctioning. If a customer refuses to or fails to provide videos or photos of a claimed malfunctioning/damaged item, this return will be treated as “buyer’s remorse” and the customer is solely responsible for shipping it back.
  • If a customer claims an item is defective/damaged, the customer must provide a proof before return, with no exceptions.
  • If the return request for a damaged/defective item can be fixed with simple parts and support, we can provide the option of free replacement part(s) and advice on how to repair your item if the customer finds that to be the easier solution so you don’t have to ship a large bulky item back.
  • Once we have received the approved returned item, we will review its condition. If the item is found to be defective, we will issue a refund within 3 workdays.

 

2.When the Customer Pays For Return Shipping


In the case of a return due to customer error, return shipping is the customer’s responsibility and shipping charges are paid by the customer. Fees vary by region.

Erayak will provide the pre-paid return shipping labels to the customer and the shipping cost for returning the products will be deducted from the refund.

It is important to note that any order offered with special shipping charges is subject to a deduction of our actual outbound shipping costs.

After the 180-day returns period, customers may use the Erayak Warranty Policy for repairs if the item is faulty or malfunctioning. Please refer to the Erayak Warranty Policy for details.

Return Address

As we have warehouses in different places to receive the return products, please contact Erayak customer service by email (support@erayakpower.com) to obtain the return address.

Refund Policy

The customer can return or refund a product for up to 30 days from the date received it. Please keep the receipt or proof of purchase.

We will notify you once we’ve received and inspected your return, and let you know if the refund was approved or not. If approved, the customer will be automatically refunded on the original payment method within 3 workdays. Please remember it can take some time for the payment bank or credit card company to process and post the refund too.

Returns may be requested for a refund if one of the following conditions is met:

  • Within 30 days of receiving the goods, the customer finds that the product has been damaged during transportation and can provide a certificate of damage;
  • Within 30 days of receiving the goods, the customer finds that the product is seriously inconsistent with the description of the original product in one or more important aspects;
  • Within 30 days after the customer receives the goods, it is found that the product has a performance failure that is not artificially damaged. The customer should assist us in completing all the battery testing, and both parties confirm that the product does have quality problems.

Cancellation of order

Erayak generally sends out your orders within 1-2 business days. To cancel an order, please contact Erayak as soon as possible to cancel the order and the customer will get a refund within 12 hours if the products are not sent out.

But if the product for the order has been shipped, we will refund the payment within 3 workdays after the shipped product is returned.

To cancel your order, please contact us via support@erayakpower.com.

Great!

Works great! I don’t have an outlet in the back of my truck to charge anything and this works great! Just plug it in to the 12v outlet and you have instant 110 outlets! Great value for the money! Nice find! Not huge! Comes with battery clamps as well! Nice design!
