Tongan power outlet

Will my hair straighteners work in Tonga?

First check that your hair straighteners can work in Tonga:

  • If your hair straighteners can run using 240 volts or can support dual voltage (how you can tell) then you will only need to bring the right power adapter listed on this page if the plug on your hair straighteners will not fit.

If not then you can either:

  • Use a power converter (or voltage transformer) - this enables you to use your existing hair straighteners and other applicances with a 240 volt Tongan power outlet, however this is noticeably bulkier, heavier and more expensive than dedicated travel hair straighteners. A power converter will change the voltage but won't change the actual physical shape of the plug on your hair straighteners to fit in the power outlet used in Tonga, so check that the power converter comes with a power adapter for Tonga otherwise you will also need to purchase another power adapter. Please note that your own existing hair straighteners might not be suited for travelling and you could risk damage in transit. [5] [AD]
Warning: If your hair straighteners won't handle 240 volts used in Tonga you run the potential risk of blowing a fuse, damage to your hair straighteners or even an electrical fire hazard. Before using your hair straighteners in Tonga please read the instruction manual first to ensure safe operation.

Travelling to Tonga with hair straighteners

Should you bring travel hair straighteners or domestic hair straighteners to Tonga?

It is preferable to bring dual voltage travel hair straighteners as opposed to bringing your existing domestic hair straighteners to Tonga as it is safer to assume that they'll work with the 240 volt power outlets used with a Tongan power outlet, provided that you bring the correct power adapter for Tonga.

Note that bringing your expensive domestic hair straighteners could place them at risk due to potential damage or loss in transit by an airport baggage handler in Tonga. The inconvenience and costs of repairing expensive specialised hair straighteners in Tonga might outweigh the cost of purchasing cheaper dual voltage travel hair straighteners [2] before travelling to bring along with you. If you intend to bring your own personal hair straighteners in your luggage either slot them inside a sneaker or boot to protect from light knocks, or use a heat resistant and shockproof hot tools travel case or heat travel mat for hair straighteners and curling irons which will also allow the hair straighteners to be transported whilst hot without risk of burning.   [9] [10] [AD]

Can I take hair straighteners in my carry on hand luggage to Tonga?

According to the TSA guidelines for hair straighteners there are no restrictions when bringing mains powered hair straighteners in your carry on hand luggage through airport security in the United States. The TSA suggests that you should verify that your airline which is flying you to Tonga will allow hair straighteners onboard and that they will fit in the overhead bin or underneath the seat of the aircraft. Packing your hair straighteners in a dedicated heat resistant protective hot tools travel case leaves them easily accessible by airport security checks, they can be packed away quickly avoiding a tangle of wires in your carry on luggage (the TSA suggests wrapping cords tightly around electronic items). If you do intend to pack fragile or expensive hair straighteners in your hand held luggage then it is advisable to use hard carry on luggage as this offers the most protection against bumps and knocks during transit.    [8] [9] [11] [12] [AD]

How can I minimise risk using hair straighteners?

How can I minimise risk using hair straighteners?

  • Skin protection: Wear heat resistant gloves during styling to protect hands from heat.
  • Children's protection: With 10% of children's burns being caused by hair straighteners it is recommended to look for hair straighteners which include a heat resistant end cap to keep the plates closed shut when not in use, making it easier to store out of reach of children.
  • Luggage protection: Placing hair straighteners directly into luggage without allowing them to cool down can risk damage to clothes and heating up combustible or flammable packed items. If your hair straighteners weren't supplied with a heat protective cap then wrap them in a heat mat or use a hot tools travel case to pack them into luggage whilst warm. A travel case will also keep expensive hair straighteners protected from damage during transit.
  • Hair protection: Applying a heat protectant spray prior to using hair straighteners is essential to prevent burning, as well as using the correct technique for your hair type - read our guide on how to use hair straighteners for comprehensive information.
  • Fire protection: It can take up to 40 minutes for hair straighteners to cool down so resting your straighteners on a heat mat could reduce the risk of setting fire to furniture. Forgetting to turn off hot domestic appliances can also cause fires. This risk can be reduced by using a model of straightener with a timer socket which will turn itself off automatically after a certain length of time, you can also add this feature to any basic straighteners by using a timer socket in a power outlet.    [9] [10] [13] [14] [15] [16] [AD]
How can I add a safety timer to my existing hair straighteners?

How can I add a safety timer to my existing hair straighteners?

1 in 12 owners of hair straighteners admit to forgetting to turn them off after use, unless your hair straighteners have a built in automatic timer then leaving them on could potentially start a fire. However you can add this functionality to any model even if it doesn't have an integrated timer:

  1. Add an automatic timer to any hair straighteners by plugging them into a timer socket then plugging the timer into a power outlet.
  2. Turn on the timer and use the hair straighteners as normal.
  3. After you have finishing using the hair straighteners turn off the power at the outlet.
  4. However if you forget to turn the power outlet off then the timer will automatically switch off the straighteners after a pre-set length of time. Depending on the model of timer this could be 15, 30, 60 or 120 minutes - ideally pick the shortest length of time possible.
  5. For added peace of mind use a power outlet splitter to share the outlet from the timer with both your hair straighteners and a lamp. When the timer is running both the straighteners and the lamp will be turned on, making the lamp a clear indicator that the straighteners are still being heated. When leaving a room it is second nature to ensure all lights are turned off, if the lamp is still on then this acts as a reminder to switch off the straighteners.
