Live chat support is available on Bestek’s website. You can chat with a support agent in real-time. This method is quick and easy. It’s good for immediate help.

Which Email Address Should I Use for a Warranty Claim?
Use [email protected]. BESTEKdirect lists it as the customer service email for warranty claims and other issues. The general contact page lists a similar-looking address for general inquiries, spelled “[email protected]” (without the “k”). Copy the warranty address from the warranty page to avoid a bounced message.
Are Support Contacts Different by Sales Channel or Country?
Yes, by sales channel. The warranty-and-return page lists separate emails for Amazon, eBay, Wish, Walmart and Bestekmall orders. Send your claim to the address for the store where you paid. The sources used here do not describe country-specific support hours or addresses, so if you are outside the U.S., confirm on your regional Bestek site.

Go To The Bestek Website
First, visit the Bestek website. Look for the FAQ or knowledge base section.
Find The Faq Or Knowledge Base Section
Next, find the FAQ or knowledge base section. These sections have many articles and answers.
Search For Your Issue
Finally, search for your issue. Use keywords related to your problem. You may find a solution without contacting support.
Basic Troubleshooting Before You Write
Support will likely ask what you already checked, so run through these first and note the results:
- Check that the battery or DC source is charged and the cable clamps or plug are seated firmly.
- Confirm the connected device’s wattage is below the inverter’s rating. An overload usually triggers an alarm or shutdown.
- Unplug everything, wait a minute, and restart the inverter with no load attached.
- Check any fuse in the DC plug or the inverter’s own fuse, if your model has one.
- Try a different, simple load, such as a lamp, to rule out the device itself.
Understanding Bestek’s Warranty and Returns
Bestek offers warranties on their products. Here are some key points to remember:
- Check the warranty period for your product
- Keep your receipt or proof of purchase
- Contact Bestek if your product is defective
Check The Warranty Period For Your Product
Each Bestek product has a different warranty period. Check your product’s warranty details.
How Long Is the Warranty on Bestek Power Inverters?
Power inverters are listed with an 18-month warranty on the BESTEKdirect warranty page. Count from your purchase date, and note that the date on your receipt or order confirmation is what you will need to prove.
Keep Your Receipt Or Proof Of Purchase
Always keep your receipt or proof of purchase. You may need it for warranty claims.
Does Bestek Offer Returns or a Money-Back Guarantee?
Yes. The warranty page states a 30-day money-back guarantee for any reason, and says unopened products may be returned within 30 days of purchase for a replacement or refund. Because the page mentions unopened products, ask support whether an inverter you have already tested still qualifies before shipping anything.
Contact Bestek If Your Product Is Defective
If your product is defective, contact Bestek. They will guide you on how to return it.

Hello, I bought a Bestek power inverter on March 3 through [store name], order number 123-4567890 (receipt attached).
