You would imagine that buying Apple products such as chargers or cables from Amazon would mean you're getting the real thing, but it seems that's not always the case. According to a lawsuit filed by the iPhone maker, 90 percent of Apple power accessories found on the retail site are fake, even those labeled as genuine.

Patently Apple reports that the Cupertino company is suing US-based firm Mobile Star LLC for trademark infringement, alleging that it has been selling counterfeit goods using Apple logos and product images in its listings.

Apple states in the lawsuit that, so far this year, it has bought more than 100 Apple-branded products from Amazon, such as "iPhone devices, Apple power products, and Lightning cables," 90 percent of which turned out to be fake. Mobile Star is reportedly responsible for the "majority" of these items.

Buying one of these fakes doesn't just mean you're missing out on an authentic Apple product, you could also be putting yourself at risk. Apple says they're often poorly built with inferior or missing parts, flawed designs, and inadequate electrical insulation. Meaning they have the potential to cause fires or even "deadly" electric shocks.

Apple argues that its reputation is damaged when consumers buy these products. The company is seeking an injunction against Mobile Star selling any more of the fake goods, destruction of all counterfeit items, and damages of $150,000 for alleged copyright infringement and up to £2 million for trademark infringement.

When Apple alerted Amazon to the fake Mobile Star products, the retail giant handed over all the stock purchased from the company. Amazon said it "has zero tolerance for the sale of counterfeits on our site. We work closely with manufacturers and brands, and pursue wrongdoers aggressively."

Just remember: if you find something that seems too good to be true when shopping online, it probably is.
