Buying from AliExpress

AliExpress is a legitimate marketplace that is worth using for cheap, low-risk things like cables, tools, cleaning supplies and small home items, as long as you can wait and you buy from well-rated sellers. Skip it for anything safety-critical, brand-name or urgent. Check the seller's feedback score, the delivery estimate and the import-charge line at checkout before you pay.

Shipping
AliExpress's 2024 US guarantee listed Choice orders at 5 to 12 days and standard orders at 8 to 14 days, but real-world standard shipping from China often runs longer. Items marked Ship from United States come from local stock. Free shipping on Choice orders depends on a minimum order shown at checkout.
Returns
Eligible items can be returned within 90 days of payment, with the first return on each order free, according to AliExpress's 2024 US announcement. Return terms vary by seller and item, so check the product page. Custom, perishable and hygiene items are generally excluded.
Warranty
AliExpress does not publish a marketplace-wide product warranty. Coverage depends on the individual seller, and Buyer Protection covers non-delivery, damage and not-as-described claims instead.
Payment
US shoppers can pay by Visa, Mastercard, American Express or Discover, PayPal, Apple Pay and Google Pay. Instalment options such as Klarna and PayPal Pay Later appear on some orders, and availability varies.
International
AliExpress sells to shoppers worldwide. For US orders, import duties on low-value parcels have applied since the duty-free exemption ended in 2025, and state sales tax is added at checkout.

Frequently asked questions

Will it fit my power supply?
Most 12V supplies use a 2.1 x 5.5 mm barrel, but inner pin sizes vary. Measure your plug or compare with the one on the device before ordering.
How much current can it handle?
The listing does not give a current rating. Keep loads modest, such as small LED strips and cameras, and check that the connector does not get warm.
How do I wire the polarity?
Barrel jacks on 12V gear are normally center positive, but check the label on your device and power supply. Confirm with a multimeter before connecting, because reversed polarity can damage LED controllers and cameras.
