After an online shopper spotted a $0.99 inverter-battery deal on AliExpress, they assumed it wasn't real and was likely a scam.
But because it was less than a dollar and the combo appliances can cost hundreds to thousands of dollars, the buyer took the risk before sharing their experience with Reddit's r/Solar DIY community.
Here's what to know
The listing showed only one unit remaining and more than 500 sales. The buyer recounted the purchase in the Reddit thread, saying they found the offer while browsing Eco Worthy products on AliExpress.
The original poster wrote, "I don't even know what made me attempt it, but I told my wife about it after I received a valid FedEx tracking number that showed it was a 100lb package that was actually moving through their system."

The Reddit discussion attracted hundreds of comments and over 1,800 upvotes as readers debated what might actually arrive. Many just added jokes to the thread, including one user who wrote, "Shipping was $1,000 I bet." Another commenter joked, "Someone's getting fired from their scammer job."
Others just shared their jealousy, like one commenter who wrote, "that's a $900 battery," and another user who added, "I think I spent like $700-$900 for mine." The OP later updated their post to confirm they received the equipment and that "this deal is wild."
For homeowners exploring battery products beyond a marketplace gamble, EnergySage offers a resource for comparing options and competitive installation estimates. EnergySage has partnered with electrification company Qmerit to help homeowners secure the best available battery-storage pricing through a more structured route for shoppers weighing equipment and installation costs.
Home battery storage can provide backup electricity during outages and reduce dependence on the grid. When properly configured, these systems can also support off-grid use. Beyond the purchase price, a properly sized home battery can help households manage electricity costs by storing power for use when utility rates are higher.
For a smaller-scale backup option, Pila offers a plug-and-play format at a substantially lower price point than whole-home backup systems. Pila's batteries can help renters and homeowners back up individual appliances, like fridges.
