Not good. Only powers 500W in AC mode

FALSE ADVERTISING. It can only power 500W of anything that requires ac current, however this is not disclosed ANYWHERE. Piece of junk.

Thank you for sharing your feedback, and we&#39;re sorry to hear about your experience.<br /><br />The DELTA 3 Classic is designed to provide up to 1,800W of continuous AC output (with higher surge capability for startup loads) under normal operating conditions. If your unit is only delivering around 500W of AC output, that is not the expected performance and may indicate a configuration issue or another factor affecting operation.<br /><br />We&#39;d like to help investigate this further. Please reach out to us at support&#64;ecoflow.com or call us at &#43;1 (800) 368-8604, Monday to Friday, 9 a.m. to 7 p.m. (EST). We&#39;re here to help and will do our best to resolve your issue quickly.<br /><br />We appreciate your feedback and look forward to assisting you.

Beware of fraud.

This appears to be a fraud from Sam's Club. The add is billed as a EcoFlow Power Bank and my Fed Ex shipping label shows 2.2 pounds vs 26 pounds, what a power bank of this size should weigh. It is supposed to arrive in 3 days so time will tell if SAM'S CLUB IS A FRAUD or not. Buyer beware. Read the other reviews.

it says right on it that the power bank ships seperatly. so you will get two shippments.

Thank you for taking the time to share your feedback.​<br />Yes, that&#39;s correct. The EcoFlow DELTA 3 Classic and the Magnetic Charging Power Bank may be delivered separately due to the shipping and fulfillment process. As a result, customers may receive their order in two separate shipments with different delivery dates.​<br />We truly appreciate you taking the time to share this information, as it helps clarify the shipping process for other customers. Thank you for your support and for choosing EcoFlow.

Buyer Beware

I only received the mag power bank, no echo flow. Essentially paying 450.00 for a cell phone charger. Getting this resolved has been a headache.
