Should I use a power bank in Tonga?

Because the power grid isn't available to 100% of the population of Tonga combined with the lack of a reliable power grid, travellers should bring alternate charging solutions if they need to continue charging devices such as mobile phones or cameras.

  • During a trip increased reliance on smart phones for storing itineraries, taking pictures, social network sharing, GPS and web browsing will syphon off power more excessively than normal. A flat smart phone battery can potentially leave you stranded without adequate power to make emergency calls or being able to use a GPS app to get directions to your hotel or accommodation. Bringing a portable charger [4] lowers that risk as it allows you to power up your mobile phone on the move, especially when visiting a country with a lack of access to electricity and power outages in some areas.
  • A 10,000mAh portable charger [4] will supply enough energy to power around three full charges whilst a 20,000mAh power bank [9] should keep an average mobile phone charged for around 7 days. The mAh rating (or milli ampere-hours) shows the capacity of the battery and gives an indication of how many cycles the portable charger can do.
  • If you need to charge your laptop in Tonga and your laptop it supports USB-C charging then bring a portable charger for a laptop [10] marked with PD (power delivery) which supplies at least 20 Wh. However be aware that some airlines won't allow you take power banks on an aircraft with more than 100Wh of power and must not be left in checked-in luggage so always ahead with the airline.
  • Average consumer portable chargers aren't powerful enough for use with high powered items, but a rechargeable hair dryer [7] or gas hair straighteners [8] are available for travelling to areas with both power cuts and limited access to electricity like Tonga.

Will a solar battery charger work in Tonga?

Solar backpacks are ideal in hot weather

Will a solar battery charger work in Tonga?

The sunlight in Tonga will be adequate enough to recharge solar power bank [12] reliability, however it needs to be left in strong sunlight to provide enough energy for a single charge cycle. This may prove inconvenient to continually unpack a solar power bank then wait whilst it recharges in sunny spells.

  • Instead, the much larger durable panels used on a solar backpack [11] give the backpack the ability to generate more electricity within a shorter period of time and might still generate power when overcast, meaning they should perform well in Tonga.
  • Phones that have been directly plugged into a USB charging port of a backpack will trickle charge the power during sunny periods in Tonga, however could be inconvenient to have a phone continuously tethered to the bag during the day if it is to be used constantly. Therefore it is recommended to plug in a battery power bank [4] into a solar backpack which can then be continuously powered up during sunlight, afterwards you can recharge your phone using the power bank at any time without daylight.
  • Even though the sunlight in Tonga is strong, a bag should have a solar cell efficiency of 22% or greater, be able to generate a minimum of 6 watts of power and includes a compatible power bank of 10,000mAH or greater.
  • The durable and flexible solar panels used in solar powered bags have been built to survive scratching and bending, unlike regular firm solar panels. Solar bags are found in rucksack, backpack and laptop messenger styles making them perfect for work, domestic and travel use.

What is a USB travel power charger?

A USB travel charger is a dual voltage charger with interchangeable plugs and multiple USB ports, suitable for charging multiple USB powered devices when travelling abroad.

Why use a travel USB charger for Tonga?

  • Most travel USB chargers include 4 or more USB charger ports, meaning you now only need to bring a single charger to charge multiple devices. Instead of bringing 4 individual power chargers you only need to pack a single 4 port USB wall charger to power up to 4 devices, thereby cutting down on the weight and size of your baggage.
  • Most travel USB power chargers should include interchangeable plug heads for various regions making them ideal when visiting different countries across Oceania which will probably use different outlets to Tonga.
  • A good power charger is lightweight, compact and rugged - perfect for rigors of travel instead of than risking bringing a domestic charger which could be hard to repair or replace in Tonga.
  • USB chargers will accept both the 240 volt power outlets in Tonga along with different voltage standards in other countries.
  • It is possible that hotel bedrooms or accommodation in Tonga only have a single power outlet, by using a travel charger with multiple USB ports means you can share the single power supply with all your devices rather than waiting to charge one device at a time.
  • Because of their versatile nature they take the uncertainty out of visiting an unknown country as they are guaranteed to work practically anywhere around the world.
  • Power outlets found in airports are often sparse and demand for charging multiple cell phones and tablets from other passengers before a flight can be high, therefore a USB charger with multiple ports and the capability to fast charge is ideal.
  • Sometimes the power grid in a country can be unstable, a quality travel charger allows for unexpected spikes and prevents damage to any devices attached to it. Trying to repair an overloaded mobile phone or tablet in Tonga might prove to be problematic and costly.
  • Larger USB chargers will also feature a power outlet strip to use multiple low powered domestic appliances such as laptops, however these are unsuitable for high powered appliances such as hair dryers or clothes irons. Read our guide on using travel appliances in Tonga for useful advice on the best power adapter for a Tongan power outlet for high wattage devices.
  • Certain cellphones and tablets could pull more than the usual 500 milliamps supplied by a standard 5 volt USB adapter to charge or provide fast charge. More expensive USB travel chargers will support fast charging should some of your devices need additional power.
  • On back at home travel USB power chargers can also be used by recharging multiple mobile phones and tablets on an overnight basis using one power outlet.

Also known as: electrical converter, electrical transformer, voltage converter, power transformer or voltage transformer.

What is the difference between a power converter and a power adapter for Tonga?

A heavy and bulky power converter [14] will convert a 240 volt Tongan power outlet to work with a non-240 volt appliance, but a more lightweight and cheaper power adapter (or plug adapter) will change the shape of the plug on your appliance to fit into a power outlet found in Tonga.

Do I need a power converter for Tonga?

If you are visiting Tonga from another country check that the device can be used with a 240 volt power supply.

  • You need a step down power converter [15] if you are travelling from a country that uses 100-120 volts and your device or appliance is incompatible with 240 volts. Read the list of world power outlets guide to see which voltage your country uses.
  • You shouldn't need a power converter if you already own either a 240 volt single voltage device or one that is dual voltage.
  • Typically, devices designed for a lower voltage (for example 110 volts) and then used with 240 volts run the risk of an electrical fire hazard, blowing a fuse or damage to your device.
  • You shouldn't need a converter if you are attempting to charge a smaller electrical device such as a tablet or mobile phone as these are typically support dual voltage and designed for international use, but you should always always check the device for dual voltage support prior to your journey.
  • For powering appliances which draw more power or generate heat (such as hair straighteners and clothes irons) then you will need to use a bulkier higher wattage heavy duty power converter [16].
  • It could be more cost effective to use a smaller robust dual voltage travel appliance than carrying a heavier high wattage power converter just to use your existing domestic appliance.
  • Read these comprehensive guides on how to use curling irons, clothes irons, hair dryers and hair straighteners in Tongan power outlets , along with guides for affordable dual voltage alternatives.

Will I need a power converter if I'm travelling to Tonga from America?

What is the difference between a power transformer and a converter?

Voltage converter

What is the difference between a power transformer and a converter?

Converters and transformers are both used to change one voltage to another, but this ambiguity can cause confusion as their purposes are different:

  • Power converters are designed for simple electrical appliances which typically generate heat or use motors such as clothes irons, shavers or hair dryers. Transformers are designed for more complex electronic items such as televisions or games consoles.
  • Buying a power converter is cheaper than buying a power transformer.
  • Power transformers are larger and heavier making them more suited for permanent residential use; for example an expat wishing to use an imported television would need to use a transformer for this purpose.
  • Power converters are more suitable for travellers wishing to bring domestic appliances abroad such as hair dryers or flat irons. However, it is more practical and cost effective to purchase a dual voltage appliance designed for travel rather than a heavier power converter.
  • Power converters are suitable for 2 pin ungrounded appliances, it could be harder to find a converter if you want to use a grounded 3 pin appliance.
  • Transformers can be used constantly however it is recommended that converters are used for no longer than a couple of hours at a time.
  • Shops may sell transformers under the name of converters, for the purposes this guide we will be referring to both converters and transformers as converters.

How to convert 240 volts to 110 volts

  1. Use a step down power converter [15] to allow you to use a 110 or 120 volt appliance with a 240 volt Tongan power outlet.
  2. If the power converter doesn't include the correct shaped plug then it will also be necessary to plug in the power cord from the power converter into a power adapter for Tonga before plugging that into a Tongan power outlet.
  3. Some power converters include the ability to perform both step up and step down voltage conversions, therefore it may be necessary to manually switch the converter to output the voltage to the 110-120 volt range.
  4. Plug your appliance into the converter and turn the power on, your 110-120 volt appliance can now be used with a 240 volt Tongan power outlet.

What voltage does Tonga use?

Tonga uses 240 volts in their standard power outlets.

How can I tell if I have a dual voltage device?

Dual voltage hair dryer

How can I tell if I have a dual voltage device?

The easiest way to see if your device is single voltage or dual voltage is to look for either a sticker or numbers printed on the power adapter, or on the device itself, typically on the rear or near to where the power cord sits. The location might vary depending on the make and model of your unit and should also state on the box or in the instruction manual.

  • Single voltage devices might have a specific number - such as 110V.
  • Single voltage devices could also say a small voltage range (20 volts difference) with a dash to accomodate small voltage fluctuations - such as 220-240V.
  • Dual voltage devices will say a larger voltage range separated with a slash - such as 100/240V.
