Buying Travel Adapters for a Team: A 7-Step Checklist (From Someone Who Buys Them)

I buy things for a living. Not in a glamorous way — I'm the office administrator for a 180-person company, which means I handle everything from the coffee order to the roughly $40,000 we spend annually on travel accessories. Travel adapters land on my desk every year, usually in February, usually because someone in sales just booked a Frankfurt trip for ten days out.

This isn't a review. It's the checklist I actually run. Seven steps, and they go in order — because if you buy the adapters before you do step 1 and step 3, you will be buying them twice.

Who this is for

If you're buying one adapter for yourself, skim it and do steps 1, 2, and 3. If you're buying for a team — or standing up a corporate travel program where the same all in one plug adapter is going to an engineer in Osaka and a procurement manager in Dublin — read all seven. The failure modes at scale are different.

One quick thing before the list: if what you actually need is a european plug to us adapter for one desk in one office, don't buy a universal brick to solve a single-country problem. Narrow problems deserve narrow, cheaper, more reliable solutions. I'll come back to this in step 6.

Step 1: Build the country list before you build the cart

Not "Europe." Specific countries. Plug standards are not regional, they're national, and the exceptions are the whole point.

The shorthand most buyers use comes from the IEC plug-type nomenclature (Type A through Type O), which is a classification system rather than a single standard — the actual dimensional requirements live in national standards like BS 1363 for the UK or EN 50075 for the Europlug. The version you'll see quoted most often is:

• Type A / B — US, Canada, Japan, Mexico. Two flat pins, B adds a round ground pin.
• Type C — the two-round-pin "Europlug." Fits most of continental Europe, but it's ungrounded and rated only 2.5A at 250V. That matters later.
• Type E / F — France/Belgium and Germany/Austria respectively. Both take Type C, but only E and F give you a real ground connection.
• Type G — UK, Ireland, UAE, Singapore, Hong Kong. Three rectangular pins.
• Type I — Australia, New Zealand, China, Argentina. Two or three slanted flat pins.

Add Italy (Type L) and Switzerland (Type J) if anyone on your team travels there. Those two break the "it fits everything in Europe" assumption constantly, and they're the reason I stopped buying Type C only kits back in 2021.

Step 2: Separate "adapter" from "converter" — they are not the same product

This is where most non-technical buyers get burned, and honestly, where I got burned first.

An adapter changes the shape of the connection. It does nothing to the voltage. A converter changes the voltage — usually stepping 230V down to 120V for a single-voltage device.

If you buy adapters for a team that includes someone bringing a US-bought hair dryer or a 120V curling iron, an adapter alone will either do nothing (if the device is single-voltage) or destroy it. Most travel converters also struggle with resistive heating loads — a 1,500W hair dryer needs a converter rated well above that, and the cheap "travel converter" bricks generally aren't.

My rule, and I've said it enough times that people repeat it back to me: if it gets hot on purpose, check the label before you pack it.

Step 3: Read the label on the device, not the plug on the wall

This is the counterintuitive one, and it's the step most people skip because they think they've already solved the problem in step 1.

Plug shape is a mechanical question. Voltage and frequency are electrical questions, and they're printed on the device itself — usually in tiny grey text on the charger brick.

What you're looking for is a voltage window. Almost every laptop power supply made in the last fifteen years says something like Input: 100–240V~ 50/60Hz. That device works anywhere in the world. It just needs a shape adapter. Phone chargers, tablet chargers, most camera chargers — same story.

What breaks: single-voltage appliances. Some CPAP machines, some older shavers, most US-market hair tools, and — a surprisingly common one — the cheap desk lamps people buy teams as gifts. Those need either a converter or, better, a local purchase at the destination.

Practical rule I use: if the input window says 100–240V, you need an adapter. If it says 120V only or 230V only, you need a converter, a different device, or a plan.

Step 4: Verify the safety listing (this is not the same as a CE sticker)

Here's the part of the buying conversation that vendors push back on, which is how you know it matters.

CE marking under the EU's Low Voltage Directive (2014/35/EU) is a manufacturer's self-declaration. It signals intent to comply; it is not third-party verification. A factory can print it on the housing. RoHS (Directive 2011/65/EU) restricts hazardous substances and is also self-declared.

What you want instead, or in addition, is a third-party listing mark: UL, ETL, or an equivalent NRTL mark for cord sets and attachment plugs. For reference, cord-connected products in the US typically fall under UL 817 (cord sets and power-supply cords), while receptacle and attachment-plug configurations sit under UL 498. Those listings require an actual testing body to sign off.

I'm not going to pretend I know how every factory handles this internally. What I can tell you is what I ask for: a certificate number and the testing lab's name. Vendors who have it send it in an hour. Vendors who don't send a PDF of a generic CE declaration.

Step 5: Check the USB ports — "USB" is not a specification

This is the mistake I made in 2023 and I'm still mildly annoyed about it.

I asked a vendor to quote adapters "with USB." They came back with a worldwide travel adapter with USB that had two USB-A ports sharing 2.4A total. I meant USB-C Power Delivery capable of charging a laptop. We spent three emails talking past each other before I realized we were using the same word for two different products.

What to actually specify:

• USB-C PD, and which version. USB Power Delivery 3.0 goes up to 100W. PD 3.1 with Extended Power Range goes to 240W, per the USB-IF specification. For a laptop, 65W per port is a reasonable floor in 2025.
• Shared vs. dedicated wattage. An adapter marketed as "100W total" across four ports may split into 30W/30W/20W/20W the moment more than one device is plugged in. If someone needs 65W for a laptop, that port needs to hold 65W while other things charge.
• USB-A is fine for phones and fine for hotel-room convenience, but don't let it stand in for laptop charging.

Step 6: Standardize on one SKU — then buy spares

For a solo traveler, variety is fine. For a program, it's a liability.

When we had six different adapter models floating around, nobody knew how to use any of them, and the ones with the little sliding switches broke at roughly twice the rate of the fixed ones. In our 2024 consolidation, we cut down to two SKUs: a compact plug-shape-only adapter for laptop bags, and a larger all-in-one with a 65W USB-C PD port for people who want one thing that does everything.

Buy 15–20% more than you need. They get left in hotel rooms, borrowed and not returned, and lost in the bottom of a carry-on. At $12–25 per unit for a decent certified one, the spares are cheaper than the emergency overnight shipping you'll otherwise pay.

Step 7: Test one before you issue sixty

This is the step everyone skips, including me, twice.

Take one unit out of the box. Plug a laptop charger into it. Plug that into a wall outlet at your desk. Plug the laptop in. Confirm the charge light comes on and stays on. Then plug something into the USB-C port and confirm it actually negotiates the wattage you expect — a laptop that reports "slow charger" is telling you the PD handshake didn't happen.

There's something genuinely satisfying about handing someone a kit that just works on the first trip. It's a small thing. It also means I don't get a Slack message from Frankfurt at 2 a.m.

Things I've learned the hard way

Cheap adapters are not a good deal at scale. In 2023 I found a supplier at $6.80 a unit versus our usual $19. Ordered 120. About thirty came back with pins that didn't grip properly or housings that cracked. Between replacements, shipping, and my time, we spent more than if we'd just bought the $19 ones. I don't have hard data on what percentage of budget adapters fail — I wish I'd tracked it — but anecdotally, the failure rate on the cheap batch was somewhere around a quarter, and near zero on the certified ones.

"Universal" rarely means universal. It usually means "fits most of the countries we thought of." Check Switzerland, Italy, South Africa, and Brazil specifically before you commit.

Grounded devices need grounded adapters. A Type C Europlug adapter won't pass a ground connection through. For laptops that's usually fine. For anything with a metal chassis and a three-prong plug, it's worth the small step up to a Type E/F or Type G adapter that carries the ground.

Buy before the trip is booked, not after. Lead times on certified adapters swing hard around trade show season. Ordering in January for a March trip is comfortable. Ordering two weeks out is a coin flip.

Seven steps, in that order. The whole thing takes about forty minutes of research the first time, and about ten minutes every year after that.
