I tested 5 travel adapters. Only one didn't die on me.

← Back to Travel Tips

Cheap adapters are how I learned the difference between "this device is dead" and "this adapter is dead." Both are bad. Only one is fixable mid-trip. After three adapters failed in three different countries, I bought five highly-rated ones and put them through 12 countries to find a survivor.

Why most travel adapters fail

Cheap adapters are essentially a plastic shell wrapped around a cluster of metal contacts. When the contacts are made of soft, low-grade alloy — which is most of them — they bend, lose conductivity, and overheat. Once that happens, anything plugged into them either won't charge or will charge so slowly you'll think the wall outlet is broken.

The other failure mode: no fuse. A surge from a poorly-grounded hotel outlet (very common in older European, South American, and Southeast Asian properties) sends current straight through the adapter into your laptop. The adapter doesn't break — your laptop does.

What I actually looked for

Before testing, I narrowed the field by these five criteria. Anything that didn't tick all five was disqualified before it ever got plugged in:

• A built-in fuse that can be replaced (most include a spare in the housing)
• USB-C PD output at minimum 20W — fast enough to charge a phone or run a laptop
• Grounded three-prong support — required for laptops and most camera chargers
• Slide-out plugs that lock in place, not the cheap spring-loaded kind that bend after 10 uses
• A weight under 200g — anything heavier means the adapter pulls itself out of the wall when you plug in a charger

The five I tested

I bought one of each, mid-range price ($25–$45), and used them across 12 countries over 4 months — UK, Italy, Spain, Portugal, Greece, Turkey, Morocco, UAE, Thailand, Vietnam, Japan, Australia. Same charging routine every day: laptop, phone, electric toothbrush, occasional camera battery. Real use, not a lab test.

1. Adapter A — $28: died on day 4 in Lisbon. USB-C stopped delivering power. Visible discoloration around the port.
2. Adapter B — $35: lasted 8 weeks. Slide-out UK plug got stuck in the open position. Couldn't close it to repack.
3. Adapter C — $42: lasted the full trip but was almost twice the size of the others. Permanently lived in my bag's outside pocket because it didn't fit inside.
4. Adapter D — $25: failed in Athens. Outlet at the hotel had a partial short, the adapter's fuse blew (which is what it's supposed to do) — but the replacement fuse it shipped with was the wrong amperage.
5. Adapter E — $39: survived everything. Still in service. Two fuses replaced over the four months (both available at any electronics shop). The one I'd buy again.

The winner

Adapter E was a Tessan-branded all-in-one. The reasons it won: serviceable fuse with the right spare included, 30W USB-C output (fast enough for most laptops), genuinely grounded three-prong support, and an indicator LED that tells you whether the outlet you've plugged into has a working ground (a surprisingly useful diagnostic when a hotel's wiring is suspect).

It's not the cheapest. It's the only one I didn't replace mid-trip. Long-term, that math wins.

When to bring a power strip too

If you're on a longer trip with multiple devices, or if you're travelling with a partner, also pack a small flat 3-outlet power strip (the slim kind without surge protection, because surge protection is what the adapter is for). One hotel outlet now powers six devices through one adapter — no daisy-chained chargers, no fighting over the one outlet near the bed.

Total weight added: about 180g. Total trip-saving moments: too many to count.
