When temperatures rise, portable air conditioners suddenly become scarce. That very time pressure makes conspicuously cheap ads and unknown online shops tempting. However, professional design, a padlock in the browser, or a displayed trust seal do not prove that a real retailer is behind the site.
The 60-second check before payment
| Inspection point | Warning sign | Safer next step |
|---|---|---|
| Web address | Typos, an unusual domain ending, or a link from a social media ad | Check the address character by character and search for the retailer independently. |
| Price | In-demand device costs significantly less than at several well-known shops | Compare market prices and ignore any claimed remaining time or quantity. |
| Imprint | Company name, address, phone number or commercial register information are missing or do not match | Cross-check the information in independent directories and on official company websites. |
| Payment | In the end, only bank transfer, cryptocurrency, or another form of advance payment without protection remains | Do not pay; prefer invoice, credit card, or established payment services. |
| Trust seal | Seal is just an image and does not link to a valid certificate | Click the seal and search for the shop directly on the seal provider's site. |
| Reviews | Only overly enthusiastic comments in the shop or very young review profiles | Search independently for the shop name plus 'experiences' or 'fraud'. |
| Warning lists | Shop is unknown or already reported | Check the URL on Watchlist Internet and in the Fake-Shop Detector. |
Why the padlock symbol is not enough
An encrypted connection protects the transmission, but says nothing about who operates the shop. Fake shops can also use HTTPS, copy company data and insert trust seals as images. The Federal Criminal Police Office also warns of cloned shops that imitate well-known companies and appear high in search results through paid ads.
Particularly critical: advance payment to an unknown seller
With a bank transfer the money is not automatically recoverable. If multiple announced payment methods suddenly change to advance payment only during the ordering process, cancel the purchase. A credit card payment or a payment service may offer additional complaint options, but does not guarantee a refund. Also do not provide a copy of your ID just to order an ordinary household appliance.
Already paid or entered card details?
- Contact your bank, card issuer or payment service immediately and ask about blocking, chargeback or complaint procedures.
- Secure the shop URL, product page, order confirmation, payment receipt, emails and screenshots.
- Monitor your account and card for unknown charges and change any reused passwords.
- File a police report if you suspect fraud and hand over the secured evidence.
A fake shop typically does not deliver at all. To be distinguished from that are retailers who send poor-quality or differently described goods. Even then, the right of withdrawal, warranty, or buyer protection can be relevant, but enforcing them with suppliers outside the EU can become cumbersome.
Check the shop first, then the device
If the retailer seems plausible, compare cooling capacity, room size, exhaust venting, noise level and energy consumption. Our overview explains, what is important when buying an air conditioner. The same basic rules also apply to other sought-after online offers, for example when buying concert tickets on risky secondary markets.
Frequently Asked Questions
Is an extremely low price proof on its own?
No. It is a warning sign that should be checked together with the domain, imprint, payment method and independent reviews.
Can I trust a seal of approval?
Only if it is clickable and the provider's official site confirms a valid certificate for that exact shop.
