Cambodia's wall sockets are a mixed bag — mostly Type A and Type C, with the odd British-style Type G in newer hotels — and the power runs at 230V, double what US devices expect. After comparing plug coverage, USB output and tens of thousands of owner ratings, this is the adapter we'd tell a friend to pack.
Last updated: October 19, 2026
Here's the good news first: if you're coming from the US, your phone and laptop chargers will almost certainly work in Cambodia — nearly all of them are dual-voltage (check the fine print for "Input: 100–240V"). What they can't do is physically fit. Cambodia never standardized on one socket, so a single trip can mean flat US-style pins in one guesthouse, round European pins in the next, and a chunky three-pin British socket in a newer Phnom Penh hotel. That's why a universal adapter earns a spot on our buy before you fly list: one cube, every socket, problem solved for the whole trip — and for Thailand and Vietnam on the way through.

Check price on Amazon →The short version: pack the EPICKA TA-105. Its sliding pins cover Type A, C, G and I sockets — everything Cambodia (and 150+ other countries) can throw at you — and it charges six things at once: a plug-through AC outlet, four USB-A ports and a USB-C port. It costs about twenty bucks and weighs about 150 g. Just remember: it's an adapter, not a converter — it changes the plug shape, not the 230V voltage.
Sockets: mostly Type A (two flat pins, like the US and Japan) and Type C (two round pins, like Europe). Some newer hotels and apartments add Type G (three chunky rectangular pins, like the UK). Many Cambodian sockets are "hybrid" designs that accept both A and C — handy, but don't count on finding the exact one you need in a rural guesthouse.
Voltage: 230V / 50Hz, versus 120V / 60Hz in the US. Phone chargers, laptop bricks, camera chargers and most modern electronics are dual-voltage and only need the plug shape changed. Single-voltage gear — many US hair dryers, curling irons, electric kettles and cheap toothbrush chargers — will fry on 230V even with an adapter. Read the label before you pack it; if it doesn't say 100–240V, leave it home.
Adapter ≠ converter. This class of product only reshapes the plug. If a device truly needs 120V, you need a voltage converter (heavy, expensive, often unreliable) — or better, buy a dual-voltage version of the appliance, or use the hair dryer the hotel provides.
It covers the whole Cambodian mix in one cube. Slide out the round pins for a Type C socket in Siem Reap, the flat pins for a Type A socket in Kampot, the three-pin block for a Type G socket in a new Phnom Penh hotel — no bag of loose plug tips to lose, and the same cube keeps working in Thailand (A/C), Vietnam (A/C) and pretty much everywhere else on a Southeast Asia route.
The USB ports solve the real Cambodian problem: not enough sockets. Older guesthouse rooms often have exactly one reachable outlet, nowhere near the bed. The EPICKA turns it into a charging station — four USB-A ports plus a USB-C (5.6A total smart output) handle two phones, a power bank, a camera battery and earbuds overnight, while the AC pass-through stays free for a laptop brick.
It's built for the way adapters actually die. A built-in 10A fuse (with a spare included) sacrifices itself instead of your gear if something goes wrong, safety shutters keep curious fingers and dust out of the live slots, and the housing is flame-retardant polycarbonate. Owners repeatedly praise the snug fit — no wobbling half-out of the wall, which is the everyday annoyance with bargain adapters.
It's small, light and proven. At roughly 150 g it's carry-on friendly, and 18,000+ ratings averaging 4.7 stars — plus years as a Wirecutter pick — make it one of the most battle-tested travel accessories on Amazon.

Ceptics Universal Travel Adapter 45W (11-KU) (4.6★ from 18,000+ Amazon ratings; $22.99 on Amazon when checked October 19, 2026 — prices change) covers the same A/C/G/I plug types, but its USB bank is a generation newer: 45W of total output with USB-C Power Delivery and Quick Charge 3.0 across two USB-C and three USB-A ports — enough to genuinely fast-charge a phone and trickle a small laptop at the same time, where the EPICKA's USB-C is phone-speed only. Trade-offs: the 45W is shared, so speeds sag when all five ports are busy; the fuse is 8A rather than 10A; and it costs a few dollars more. If your travel kit is USB-C-heavy, it's the better cube; for everyone else, the EPICKA's price and track record keep it on top.

Mostly Type A (flat two-pin, like the US) and Type C (round two-pin, like Europe), with Type G (UK-style three-pin) appearing in newer hotels and apartments. Many sockets are hybrids that take both A and C plugs. A universal adapter with A, C and G pins covers every socket you're realistically going to meet.
Almost certainly just an adapter. Cambodia runs on 230V; phones, laptops, cameras and most modern chargers are dual-voltage (100–240V) and only need the plug shape changed. A converter is only for single-voltage 120V appliances like many US hair dryers and curling irons — and the smarter move is to leave those home or buy dual-voltage versions.
Yes. Thailand uses Type A and C (occasionally B), Vietnam uses A and C — all covered by the same sliding pins. That's the real payoff of a universal cube on a Southeast Asia trip: one adapter rides in your daypack across every border, no new purchase per country.
You can — markets and phone shops in Phnom Penh and Siem Reap sell cheap plug adapters for a dollar or two. But "cheap" shows: loose fits that spark and slip out, no fuse, no USB ports, and no way to know what's inside the plastic. For something your phone and laptop depend on nightly, the tested, fused adapter bought at home is worth the twenty bucks.
Power is the unglamorous problem that can quietly ruin travel days — dead phone, no map, no photos. For about twenty dollars, the EPICKA TA-105 removes it entirely: every Cambodian socket type in one light cube, six devices charging from a single guesthouse outlet, and a fuse standing guard. It sits near the top of our buy before you fly gear list because it's the rare travel accessory that is cheap, light and genuinely buy-it-for-life.
