Lombok uses European-style Type C and Type F power plugs (two round pins) at 230V and 50Hz. Travelers from the US, UK, Australia, and countries using different plug types need a travel adapter. Most modern phone and laptop chargers are dual-voltage (100-240V) and only need a plug adapter, not a voltage converter.
Indonesia, including Lombok, uses the European-standard electrical system:
If you are from continental Europe, your plugs will fit directly — no adapter needed. If you are from the UK, US, Australia, or any country using different plug types, you will need a plug adapter.
### No adapter needed:
### Need a Type C/F adapter:
A simple Type C adapter (two round pins) is the most universally useful adapter for Indonesia. These are small, lightweight, and cost $3-10 for a basic version.
Recommended approach: Buy a universal travel adapter that covers multiple countries. These include swappable or rotating plug heads for Type A, C, G, and I, fitting sockets worldwide. Brands like Ceptics, Bestek, or generic universal adapters are widely available at airport shops and online retailers. A good universal adapter with USB ports costs $15-25 and covers you for Indonesia and any future travel.
USB charging note: Many modern universal adapters include USB-A and USB-C ports, which means you can charge phones and tablets directly from the adapter without needing your original charger. This reduces the number of items you need to pack.
Voltage is the critical safety consideration. Indonesia runs at 230V. Some countries (notably the US, Canada, and Japan) run at 110-120V. Plugging a 110V-only device into a 230V outlet will damage or destroy it, potentially causing a fire.
How to check your devices:
Look at the small text on your charger or power adapter. Every electrical device sold internationally has its input voltage printed on it.
Common dual-voltage devices (safe with just a plug adapter):
Common single-voltage devices (need converter or leave at home):
Practical advice: Rather than packing a heavy, expensive voltage converter for a hair dryer, either buy a cheap local hair dryer in Lombok (available at shops in Mataram for 100,000-200,000 IDR) or ask your hotel — most provide hair dryers as in-room amenities.
Indonesia's state electricity company (PLN) provides power across Lombok, and the grid is generally reliable in developed areas. However, Lombok is not immune to outages.
Tourist areas (Kuta, Senggigi, Gili Islands): Power is reliable. Most hotels and established businesses have backup generators. Outages are brief and infrequent — when they happen, generator power kicks in within seconds at better accommodations.
Rural areas: Power is available but less stable. Voltage fluctuations and brief outages are more common. If staying in a basic homestay in a rural area, a voltage fluctuation can affect sensitive electronics. A small surge protector is worth packing if you carry expensive equipment.
Gili Islands: Despite being small islands, the Gilis have reliable power provided by undersea cable from mainland Lombok plus local diesel generators as backup. Charging devices on the Gilis is straightforward.
Rinjani trek: No power on the mountain. Charge all devices fully before starting the trek. A portable power bank (10,000-20,000 mAh) keeps your phone alive for the entire 2-3 day trek if you use it judiciously (airplane mode saves enormous battery).

A few practical notes about charging devices in Lombok:
Bring a Type C/F travel adapter (or a universal adapter), verify your chargers are dual-voltage (almost all modern ones are), and pack a portable power bank. That covers every electrical need you will have in Lombok. The electrical system is reliable, charging opportunities are plentiful, and power is one of the least stressful aspects of traveling in Indonesia.
