Step Down Transformer for Chile: 220V to 110V Guide
Chile runs on 220V / 50Hz, which means US appliances — the steady flow of kitchen equipment, tools and electronics from the US market — all need a step down transformer before they plug in. From Santiago apartments to mining-town workshops, the 220V-to-110V conversion is a constant need. This guide covers the Chilean voltage reality, sizing, and what to buy for the local market.

Chile voltage reality
Chile’s standard supply is 220V / 50Hz across the country, with single-phase for households and three-phase for industry. US appliances rated 110-120V need a step-down transformer before use. The demand comes from expatriates, online imports and the large installed base of US kitchen and workshop equipment.
With a 220V nominal supply, a standard 220V-primary transformer works as designed. If your area runs slightly high or low, the output follows — that is normal, and most appliances tolerate it.
What buyers in Chile need
- 220V to 110V step-down transformers for US appliances — the staple product.
- 220V to 100V units for Japanese appliances.
- Larger units (3000-5000VA) for workshops and commercial kitchens.
- RCD-protected models for humid coastal areas like Valparaiso.
Sizing a transformer for Chile
| Appliance | Typical wattage | Recommended model |
|---|---|---|
| TV, phone chargers, lamps | 100-300W | ST-1000 (1KVA) |
| Blender, mixer, coffee machine | 300-800W | ST-1000 / ST-1500 |
| Refrigerator / freezer | 300-800W (surge x3) | ST-2000 (2KVA) |
| Microwave, iron, air fryer | 1200-1800W | ST-2000 or larger |
| Washing machine, water pump | 1000-2500W | STU-3000 / 5000 |
| Power tools (workshop) | 500-1500W (surge x3) | 3000VA |

Mining and industrial demand
Chile’s mining regions — Antofagasta, Calama, Copiapo — run workshops and camp facilities that import US equipment. Workshop transformers need surge-rated sizing and RCD protection, and the altitude and dust of the Atacama demand proper ventilation and IP54 enclosures in exposed locations. We supply project sizes for these installations.
Voltage stability and the grid
The Chilean grid is generally stable in urban areas, but long rural feeders and some regions see voltage swings. A transformer with 25-30% margin absorbs these swings. For sensitive electronics, the isolation in the ST series keeps the output clean and stable.

Importing into Chile
We ship FOB Ningbo or Shanghai with commercial invoice, packing list, CE / RoHS certificates and batch test reports. Confirm the current customs classification with your broker; transformers are a routine electrical import when documentation is complete. Distributors in Santiago and Valparaiso stock the core range.
Buying for resale in Chile
Chilean distributors stock 1000VA, 2000VA and 3000VA step-down transformers as the core range. Private labelling with your brand, Spanish labels and export-grade cartons is available from MOQ 10 pcs. The 2000VA size is the fastest mover.
The 220V primary and local accuracy
Chile runs a nominal 220V, so a standard 220V-primary transformer works as designed. If your area runs high or low, the output follows. For sensitive electronics, order a unit with input taps (220V / 230V) so the output stays accurate on either supply. This is a free option and it removes the guesswork.
A quick multimeter reading of your wall voltage tells you which tap to use. If it reads 225V or higher, use the 230V tap; if it reads 220V or below, use the 220V tap.
Earthquake considerations in installation
Chile is earthquake country, and installation practice should reflect it. Mount the transformer on a wall bracket with proper fixings, not loose on a shelf where it can jump in a tremor. Use flexible cable connections so movement does not stress the terminals. This is a small consideration that saves real headaches after any seismic event.
For workshops and kitchens, a fixed wall mount keeps the transformer out of foot traffic and away from water. It is the right habit in any country, and a necessary one in Chile.
Tourism and hospitality demand
The Chilean hospitality sector imports US kitchen and entertainment equipment for hotels and restaurants. A hotel kitchen typically needs 2000-5000VA per kitchen, and we can quote a standardised range for multi-floor installations. This institutional demand is steady and predictable.
Hotel projects also buy in bulk, which suits distributors who carry stock. We can private-label the whole range for the hotel group or the distributor brand.
Warranty and after-sales support
Every Wilmall transformer carries a 12-month warranty, and we keep common spare parts in stock for fast resolution. Batch test records ship with every order, simplifying warranty claims for Chilean importers. We respond to support enquiries within 24 hours.
The short version
For Chile, order 220V-primary transformers, size for the motor surge, keep them RCD-protected and ventilated, and mount them securely for the seismic reality. The ST-1000 / ST-2000 / STU-3000 range covers households, workshops and hotels. Email sales@wilmall.com for pricing.
Japanese 100V appliances in Chile
Japanese appliances — rice cookers, air purifiers, small kitchen devices — are also present in the Chilean market. Most are rated 100V. A standard 110V output suits them within tolerance; for motorised 100V 50Hz-only devices, request a multi-tap secondary and we will wind the output closer to 100V. The 100-110V tap option covers both Japanese and US appliances from one unit.
One transformer with the tap serves the whole imported-appliance household. That is the factory-wound advantage.
Installation in coastal humidity
Coastal cities like Valparaiso and Concepcion are humid, and salt air corrodes terminals over time. Ask for corrosion-resistant terminals and mount the transformer in a dry, ventilated spot, off the floor. The RCD test button should be accessible, and the monthly check keeps the protection layer working.
For coastal installations, IP54 enclosures are the practical upgrade. Salt air is the slow killer of outdoor electrical gear, and the enclosure stops it at the door.

Frequently asked questions
What voltage does Chile use?
Chile uses 220V / 50Hz. US appliances rated 110V and Japanese units at 100V need a step-down transformer before use.
What size transformer do I need for a refrigerator in Chile?
A refrigerator draws 300-800W with a start-up surge of about three times, so a 2000VA step-down transformer is the recommended size.
What transformer does a workshop in Chile need?
A workshop running US power tools needs a 3000VA transformer per workbench, sized for the tool surge. Commercial kitchens need 2000-5000VA.
Why is RCD protection important in Chile?
Coastal humidity and workshop conditions increase the risk of leakage faults. RCD trips on leakage current in milliseconds, protecting users and equipment.
What is the MOQ for transformers shipped to Chile?
Our MOQ is 10 pcs per model, shipped FOB Ningbo or Shanghai with full export documentation.
