Return window

You can return most items within 30 calendar days of delivery for a full refund of the item price. The window starts on the delivery date shown in the carrier's tracking.

Conditions

To be eligible, the item must be:

• unused and in the same condition you received it — you're welcome to open the box and inspect it
• complete, with all cables, accessories, manuals and any free items that came with it
• in its original manufacturer packaging, with serial numbers and labels intact
• not installed, hard-wired, mounted or connected to a home electrical system, plumbing or a vehicle

Items that can't be returned

• Transfer switches, smart home panels and other products that have been installed or wired in
• Products damaged by misuse, accident, modification or improper installation after delivery
• Items returned without prior authorization, or after the 30-day window

Defective or damaged items are always covered — see below.

How to start a return

1. Contact us within 30 days of delivery with your order number and the reason for the return: email contact@oneipower.com or call +1 (920) 259-0911 (Mon–Fri, 9AM–6PM EST).
2. We'll reply within one business day with a return authorization (RMA) number, the return address and packing instructions. Lithium batteries must be packed and shipped by ground following our instructions.
3. Ship the item within 14 days of receiving your RMA, using a trackable service, with the RMA number on the box.

Returns sent without an RMA number can't be identified and may be refused.

Return shipping costs

• Change of mind: you pay for return shipping.
• Damaged, defective or incorrect items: we pay all return shipping and send a prepaid label or arrange pickup.

Restocking fees

We don't charge a restocking fee on any return.

Refunds

We inspect returns within 3 business days of arrival and email you the result. Approved refunds are issued to your original payment method within 5 business days; your bank may take another 3–10 business days to show the credit.

• Refunds cover the item price and any sales tax charged on it.
• If a return arrives used, damaged or incomplete, we'll contact you before deciding anything. You can choose to have it sent back to you, or accept a partial refund that reflects its condition.

Exchanges

We don't make direct exchanges. Return the item for a refund and place a new order for the product you want — that's the fastest way to get it. Defective items are replaced as described below.

Damaged, defective or incorrect items

• Shipping damage or wrong item: tell us within 48 hours of delivery, with photos. We'll send a replacement or issue a full refund, including shipping, at your choice.
• Defective on arrival: if a product doesn't work within 30 days of delivery, we replace it or refund it in full and pay all shipping both ways.
• After 30 days: defects are handled under the manufacturer's warranty. See our Warranty Policy.

Order cancellations

You can cancel free of charge before your order ships. See our Order Cancellation Policy.
