— Tiffany, Co-Founder & Strategic Sourcing Partner

Last week, a UK client sent me a quotation with excitement: “Tiffany, I found a new supplier. Their price is 35% cheaper than our current one! The sample passed testing. Can I place the order?”

I looked at the quotation and replied: “When a price is unbelievably low, it’s not because the supplier is generous. It’s because there are hidden costs you haven’t seen yet.”

My Costly Lesson

Years ago, I too was tempted by a “super‑low” offer. A new factory promised me 40% cheaper prices on power adapters. Samples passed testing, so I placed the order.

But once the goods reached overseas, the nightmare began:

• 83 units failed instantly when plugged in.

• 15% of the second batch had ripple issues.

• Some casings deformed after just one week.

The factory blamed shipping, then disappeared. That “saved” 40% ended up costing me more than 400% , in money, trust, and reputation.

Where Low Prices Hide Their Tricks

Over the years, I’ve learned to dissect suspiciously cheap quotations. The traps usually hide in three places:

1. Invisible Components Cheaper capacitors, downgraded MOSFETs, fine in short tests, but fail under real use.

2. Skipped Testing Proper power supplies need safety, EMC, aging, and temperature tests. Low‑price factories cut corners, aging samples for 48 hours but bulk goods for only 2.

3. Fake or Incomplete Certifications CE, UL, UKCA reports that look real but aren’t. Many buyers forget to verify numbers until customs or regulators flag them.

The Real “Good Price”

A truly good price isn’t the lowest. It’s the one that includes:

• Proper component costs

• Full testing processes

• Valid certifications

• Reasonable supplier profit

• Buyer’s risk buffer

My rule today: if a quotation feels “too good to be true,” I assume hidden risks and investigate.

Final Note

That UK client later messaged me: “Tiffany, I checked the UL report. The number was fake. Thank you for saving me.”

I replied: “My pleasure. I just helped you see the costs you couldn’t.”

In power supplies, there are no miracles. Behind every “too‑cheap” quotation lies a risk waiting to explode. And when it does, it’s not the factory who pays , it’s you and your customer.
