Electronics are increasingly common in our lives. Smartphones and other electronics can serve multiple purposes like a Swiss Army Knife. There are even USB Swiss Army Knives, although that did not seem to work out so well (I cannot find it listed on the Victorinox website).
Newer electronics often become smaller, allowing us to travel lighter or include more items. Here are a selection of electronic related items you may like to add to your packing list:
Keep in touch making calls, send messages etc. Check your phone supports suitable frequency and is not locked to your home provider.
Mobile Phone Charger
Make sure your phone is charged for when you need it. Can often charge other devices too.
Listen to music, books, calls and block out noise (however, be mindful of your surroundings). Get an attached microphone included to make calls.
Bulkier than earphones, but generally better sound for your money as it is easier to make larger devices sound better.
Combine with an adaptor, possibly voltage converter, and be able to power multiple devices from the one power socket. Some support USB charging.
Countries may have different power sockets to your devices. An adapter allows you to change the socket type, but does not change voltage, so be careful not to ruin your device.
Sometimes replaced with a smartphone to reduce space and weight, but a camera can potentially take better pictures and has its own battery.
Use to transfer and backup data between devices. Often also used for charging.
Remember to charge your camera so you don't miss those fantastic shots.
Use e-ink, which can be easy on your eyes and do not need a lot of battery power. Most have no color.
For when a phone is too small and a laptop is too big.
Great for researching your travel, keeping in touch, making bookings, etc.
Use to storing photos, music and other data. Not a great long term backup solution, so move data onto other storage regularly.
Memory Card Reader
Often used to move photos or other data. Some laptops may have these built in to save you needing to take one.
Camera Housing (Waterproof)
A little bit risky, but these should keep your camera safe underwater.
Don't forget the charger and make sure the battery is charged and ready. In some cases you may pack a spare battery.
Enable international roaming on your service if needed. Having a local SIM card for places you are travelling can save you money.
Some devices need an external power supply, normally a small black box that plugs into a power socket.
Sometimes you need to shed some proper light on the situation. Make sure you have power when you need it.
It can be easier to use your head to light you way and leave your hands free for other tasks. Just make sure you have power for your torch.
While there are newer ways to communicate, shortwave radio still has some fans.
Developed during the Second World War, Walkie Talkies are another way to keep in touch over short distances.
Some devices cannot change voltages and require a converter. Check the voltage ranges to ensure you do not damage your device. You can either buy a new device that can deal with other voltages, or grab a converter to plug it into.
Make use of the US government satellites to know where you are in the world (if they aren't blocking you).
Digital Audio/MP3 Player
A dedicated audio device for playing music, audio books etc.
Electrical Extension Cord
For when you need to run power to a place you can't normally reach. Sometimes a powerboard will get you that little bit of extra distance in a pinch.
A dedicated video recorder for when a smart phone is not good enough.
A camera that is water resistant and allows you to take those hard to catch underwater moments.
When you don't want to risk using an expensive camera or your phone.
You might need some different lenses to get the shot you want. Remember to pack them carefully and don't leave them behind after taking a photo.
For when you are going places a normal mobile phone has no coverage, or need a backup phone.
Portable Solar Panels
Make your own power with some solar panels. Great for camping.
Changes direct current (DC) like from a car to alternating current (AC) to use with your devices.
A small fridge useful for camping, 4WD, caravans or holiday houses etc.
Used to test electrical devices and make sure voltages are at the correct levels.
A satellite radio has a much larger coverage area than normal radio stations.
Taking a hair clipper on a trip gives you flexibility to cut hair whenever you want and not need to find somewhere to have it cut. This can save you money, but comes at the trade off of some extra storage room and weight requirements in your luggage.
