Travel · Colombia · 110V / 60Hz
Colombia: nothing to buy, unless you carry on south.
Colombia runs 110V at 60Hz on Type A and Type B sockets — flat blades, optional round earth pin, the US arrangement exactly. No adapter, no converter, no dongle. The trap is regional rather than local: fly a couple of hours south and the voltage doubles.
Plugs, voltage, and what fits
| Spec | Colombia | Consequence |
|---|---|---|
| Plug types | A (two flat blades) and B (two blades plus round earth pin) | Every US plug fits, grounded ones included |
| Voltage | 110V nominal | Below US nominal, and harmless — no device notices |
| Frequency | 60Hz | Identical to the US |
| What fits | US two-blade and three-prong plugs, unmodified | Nothing to pack |
| What does not fit | Type C, F, G, I and N plugs | Only relevant to gear bought outside the Americas |
The 110V figure sometimes worries people who expect 120V. It should not. A supply rated 100–240V regulates its own output and draws slightly more current at the lower input — an iPhone on a 20W brick charges at the same speed in Medellín as in Miami. Resistive appliances run a few percent cooler, and that is the whole effect.
The trap is the next flight, not this one
South America does not share one grid, and Colombia sits on the friendly side of a line many itineraries cross:
| Country | Voltage | Plug types | Do US plugs fit? |
|---|---|---|---|
| Colombia | 110V / 60Hz | A, B | Yes — nothing needed |
| Peru | 220V / 60Hz | A, C | Yes — and that is the hazard |
| Brazil | 127V or 220V / 60Hz | N | No — Type N adapter needed |
| Chile | 220V / 50Hz | C, L | No — Type C adapter needed |
| Argentina | 220V / 50Hz | C, I | No — Type C or I adapter needed |
| Costa Rica | 120V / 60Hz | A, B | Yes — nothing needed |
| Mexico | 127V / 60Hz | A, B | Yes — nothing needed |
What to actually pack for Colombia
With no adapter to buy, the only gain is weight and socket count. A room with two accessible outlets and four devices is the real problem, and one multi-port brick beats three cubes.

Grounding, and flying with the batteries
Type B grounded sockets are standard in Colombian construction, so a three-prong US plug generally seats without drama — a better situation than Mexico or Costa Rica, where older two-slot outlets are common. Older Colombian buildings can still present two-slot sockets, and the fix there is the same: use the two-blade folding duckhead or a double-insulated 65W GaN charger rather than a cheater adapter that defeats the earth. On the flight itself, power banks go in the cabin only, under 100Wh without approval, per the limits collected in the airline rules for chargers. The rest of the country guides are on the travel adapter hub.
FAQ
Do I need a travel adapter for Colombia?
No. Colombia uses Type A and Type B sockets at 110V and 60Hz, the same shapes as the United States, so US plugs fit unmodified — including grounded three-prong plugs.
Is 110V a problem for a US device rated 120V?
No. Switch-mode supplies rated 100-240V regulate their own output and charge at the same speed. Resistive appliances such as hair dryers run marginally cooler, which is the only observable difference.
Does my Colombia adapter also work in Peru or Chile?
You will not have bought one for Colombia. Peru's sockets accept US flat blades but run at 220V, so the issue there is the device label rather than the plug. Chile and Argentina need a genuine Type C or Type L or Type I adapter.
Can I bring a power bank to Colombia?
Yes, in carry-on baggage only. Under 100Wh requires no approval, which covers every bank up to about 27,000mAh. Spare lithium batteries are never allowed in checked bags.
