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:
Digital Audio/MP3 Player
A dedicated audio device for playing music, audio books etc.
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.
Bulkier than earphones, but generally better sound for your money as it is easier to make larger devices sound better.
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 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.
Some devices need an external power supply, normally a small black box that plugs into a power socket.
Sometimes replaced with a smartphone to reduce space and weight, but a camera can potentially take better pictures and has its own battery.
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.
A small fridge useful for camping, 4WD, caravans or holiday houses etc.
Keep in touch making calls, send messages etc. Check your phone supports suitable frequency and is not locked to your home provider.
Used to test electrical devices and make sure voltages are at the correct levels.
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.
While there are newer ways to communicate, shortwave radio still has some fans.
A dedicated video recorder for when a smart phone is not good enough.
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.
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.
Use e-ink, which can be easy on your eyes and do not need a lot of battery power. Most have no color.
Great for researching your travel, keeping in touch, making bookings, etc.
Changes direct current (DC) like from a car to alternating current (AC) to use with your devices.
For when a phone is too small and a laptop is too big.
A camera that is water resistant and allows you to take those hard to catch underwater moments.
For when you are going places a normal mobile phone has no coverage, or need a backup phone.
Make use of the US government satellites to know where you are in the world (if they aren't blocking you).
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.
Developed during the Second World War, Walkie Talkies are another way to keep in touch over short distances.
Combine with an adaptor, possibly voltage converter, and be able to power multiple devices from the one power socket. Some support USB charging.
A satellite radio has a much larger coverage area than normal radio stations.
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.
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.
Sometimes you need to shed some proper light on the situation. Make sure you have power when you need it.
Portable Solar Panels
Make your own power with some solar panels. Great for camping.
When you don't want to risk using an expensive camera or your phone.
