This 65W charger died in 6 days. How not to buy the same one

Quick one, because I'm still mad. 📦

Bought a 65W "GaN" USB-C charger off a marketplace listing for $22. Two ports, tiny, 4.8 stars with 3,000 reviews. Day 6, my laptop stopped charging from it. Day 7 it stopped doing anything at all and it smelled like a hot hair dryer. No fire, no drama, just dead. My own money, and the seller has stopped answering.

So here's what I check now, and honestly should have checked then.

1. Get a USB-C power meter

The little inline USB-C testers (the ones with a tiny screen, around $15 to $25) show voltage and current, and the better ones list the Power Delivery profiles a charger advertises. Plug it between charger and device and you learn a lot in 30 seconds.

A legit 65W USB PD charger should offer fixed profiles like 5V 3A, 9V 3A, 15V 3A and 20V 3.25A. 20 × 3.25 = 65W, the maths has to work. Mine said 65W on the box and only ever negotiated 20V at 2.25A with my laptop. That's 45W. The listing was lying before it even died.

2. Read the label, then don't trust the label

• Look for a real safety mark for where you live (UL or ETL in the US) and a model number you can actually search. A blank label, or a "CE" in a weird font, is a red flag.
• If the brand claims USB-IF certification, look it up. Most cheap ones don't claim it, which at least is honest.
• Weight matters. My dead one was noticeably lighter than the name-brand 65W chargers I own. Less copper, less heat sinking, less everything.

3. Watch the temperature

GaN chargers run warm, that's normal. But if it's too hot to keep your hand on after 20 minutes of laptop charging, something is cooking. Mine was too hot to hold by day 3. I ignored it. Don't be me.

4. Only trust reviews with photos of the label

3,000 five-star reviews and maybe 20 had photos. The photos showed two different label designs. Same listing, different hardware. That's the giveaway: the seller swaps what's inside and keeps the reviews.

Total I spent learning this: $22 for the charger, $19 for the meter. The meter is staying in my bag forever.

Verdict on cheap no-name 65W chargers: Skip. Buy a brand you can search, from a store that takes returns. A $40 charger that lasts five years beats a $22 one that lasts a week, every single time.
