01Voltage & plug type
Indonesia runs on 230V with Type C/F plugs — the standard European-style two round pins. Visitors from the UK, US, Australia and most of Asia outside the EU will need an adapter; most modern phone and laptop chargers handle the voltage difference automatically, but it's worth checking your specific device.
02Bringing the right adapter
A universal travel adapter covers this easily and is worth packing before you arrive — airport shops sell them but at a real premium compared to buying one at home in advance.
03Power reliability
South Bali's tourism infrastructure generally has stable power, though brief outages do happen, more frequently in East, North and West Bali or during heavy storms. Most hotels and villas have generator backup; simpler guesthouses in remote areas sometimes don't.
04Charging on the go
A portable power bank is genuinely useful given how much a day of scooter navigation, photos and messaging drains a phone — see our packing list for the fuller list of what's worth bringing.
05Practical tips
Pack one universal adapter per person or device type you're charging simultaneously, since villas and hotels don't always have spares to lend. USB wall outlets are increasingly common in newer hotels but not universal — bring your own cable and plug regardless.
