Power Inverters

About Power Inverters

Power inverters are essential devices that convert 12v DC power from vehicle batteries or portable power sources into 240v AC mains electricity, enabling you to use standard household and professional tools away from fixed power supplies. MyToolShed.co.uk stocks a comprehensive range of power inverters from trusted brands including Sealey and Draper, offering both modified sine wave and pure sine wave models to suit different applications and budgets.

Whether you're a mobile tradesperson needing to run power tools on-site, an outdoor events professional requiring reliable portable electricity, or a motorhome enthusiast wanting home comforts on the road, a quality power inverter provides the flexibility to work and operate equipment anywhere. Available in various wattage capacities from compact 200W units to more powerful 400W+ models, many inverters at MyToolShed feature convenient USB charging ports alongside standard 240v outlets for maximum versatility.

Applications

Power inverters are invaluable for a wide range of trades and situations:

• Mobile tradespeople: electricians, plumbers, and carpenters running power tools from their vans
• Automotive technicians: powering diagnostic equipment and tools in workshops or roadside
• Camping and caravanning: running appliances, charging devices, and powering entertainment systems
• Emergency backup power: maintaining essential equipment during power cuts
• Outdoor events: powering sound systems, lighting, and catering equipment
• Agricultural workers: operating tools and equipment in remote field locations
• Construction sites: supplementing power supplies in areas without mains electricity

Choosing The Right Power Inverters

When selecting a power inverter, consider these key factors:

Wattage capacity: Calculate the total wattage of devices you'll run simultaneously, then add 20-30% for surge power requirements. Smaller inverters (200-300W) suit laptops and phone chargers, whilst 400W+ models handle power tools and larger appliances.

Sine wave type: Pure sine wave inverters produce cleaner power suitable for sensitive electronics, medical equipment, and devices with motors. Modified sine wave inverters are more economical and work well with basic tools, lights, and heating equipment.

Connection method: Lighter inverters can connect via cigarette lighter sockets, whilst higher-wattage units require direct battery connection with heavy-duty cables and appropriate fusing for safety.

Additional features: Look for built-in USB ports for device charging, cooling fans for continuous operation, and protection features including overload, overheat, and low-voltage shutdown to safeguard both the inverter and your vehicle battery.

Safety Information

Always ensure your power inverter is adequately rated for your intended load and connected securely to prevent loose connections. Never exceed the maximum wattage rating, as this can cause overheating and potential fire hazards. When connecting directly to batteries, use the correct gauge cables and install appropriate fuses. Ensure adequate ventilation around the unit during operation, and disconnect when not in use to prevent battery drain. Only use pure sine wave inverters with sensitive equipment requiring clean power.

Frequently Asked Questions

What's the difference between modified and pure sine wave inverters?

Modified sine wave inverters produce a stepped waveform suitable for most basic tools and appliances, whilst pure sine wave inverters generate smooth AC power identical to mains electricity, essential for sensitive electronics, variable speed tools, and equipment with microprocessors.

Can I run power tools from a 12v power inverter?

Yes, but ensure the inverter's continuous wattage rating exceeds your tool's requirements plus 20-30% for start-up surge. Most small power tools work with 400W+ inverters, though larger equipment may require higher capacity units and direct battery connection rather than cigarette lighter sockets.

Will using a power inverter drain my vehicle battery?

Yes, power inverters draw from your battery, so run your engine periodically during extended use to maintain charge. Most quality inverters include low-voltage protection that automatically shuts off before completely draining the battery, preventing starting issues.
