Your phone is already the ultimate camping multitool. It is your map, your camera, and your weather forecaster. But did you know it is also a portable battery? With the right little accessories, you can turn your phone into a fan, a reading light, or even a midge repeller.
I used to carry loads of separate batteries for these gadgets, until I realised I could just power them from the device already in my hand. It saves weight, space, and hassle. But to make this magic happen, you need one very specific little tool first.
The Secret Weapon: USB-C OTG Adapter
Before we get to the gadgets, you need this. Most camping accessories use the big, standard USB (Type-A) plug. But modern phones have the small oval USB-C port.
This tiny dongle (called an OTG or "On-The-Go" adapter) bridges the gap. It plugs into your phone and creates a standard USB socket, letting you plug anything into your mobile. It costs pennies but unlocks everything below.

1. The Flexible USB Fan
Instant Breeze
On a humid summer night, a stuffy tent can be a nightmare. This simple gadget is a lifesaver. It is just a flexible stick with a motor and two soft blades. Plug it into your phone (via the adapter), and you have instant cooling.
It is silent enough to sleep with and uses surprisingly little power. I often hold my phone to read an eBook while the fan gently cools my face. It is a tiny luxury that costs less than a coffee.
Pros
- Instant cooling relief.
- Bendable neck to aim airflow.
- Soft blades are safe.
Cons
- Can drain battery if left on all night.
2. The "Snake" Reading Light
Better Than a Head Torch
I love reading in the tent, but wearing a head torch is uncomfortable, and holding a torch is annoying. This flexible USB light is the perfect solution. It plugs into your phone and creates a focused pool of light exactly where you need it.
Because it runs off your phone's battery, it saves your head torch batteries for when you really need them outside. It is also great for finding things in the bottom of your sleeping bag without waking everyone else up with a blinding beam.
Pros
- Soft, focused light.
- Infinite adjustment.
- Very low power consumption.
Cons
- Not bright enough for walking outside.
3. The USB Midge Banisher
Essential for Scotland
If you camp in Scotland or the Lake District, midges are the enemy. This clever little gadget heats up a small repellent mat (like the ones used in plug-in home diffusers) to create a protective bubble.
Usually, these require mains power, but this version runs off standard USB. Plug it into your phone via the adapter for 20 minutes before bed to clear the tent of pests. It is incredibly effective in small, enclosed spaces.
Pros
- Creates a bug-free tent.
- Silent operation.
- Uses standard refill mats.
Cons
- Gets hot (be careful).
- Drains battery faster than a light.

4. USB String Lights (Fairy Lights)
Instant Atmosphere
Camping should be cosy. Harsh white lantern light can kill the mood. A cheap set of USB powered copper wire lights weighs almost nothing but transforms a tent into a magical space.
Plug them into your phone and drape them over your tent poles. They provide a lovely warm glow that is perfect for relaxing in the evening. Because they use tiny LEDs, you can run them for hours without worrying too much about your battery percentage.
Pros
- Beautiful warm ambient light.
- Extremely lightweight.
- Makes your tent easy to find in the dark.
Cons
- Wire can tangle easily.

5. The USB Plasma Lighter
Windproof Fire Starter
Okay, you don't keep this plugged in while you use it, but you recharge it from your phone. Disposable lighters run out of gas and struggle in the wind. A plasma lighter uses electricity to create a super-hot purple arc that ignites stoves and campfires instantly.
It is totally windproof and waterproof. If it dies, just plug it into your phone for 15 minutes, and it is ready to go again. It is a modern, sustainable upgrade to matches.
Pros
- Totally windproof.
- Rechargeable anywhere.
- No gas required.
Cons
- High pitched noise when active.
Frequently Asked Questions
Will these gadgets drain my phone battery?
Yes, they draw power directly from your phone. Small items like the fan or LED light use very little power (you might lose 5-10% charge over an evening). However, if you are running them for hours, I strongly recommend carrying a power bank to top your phone back up.
Do I need a specific OTG adapter?
You need a "USB-C to USB-A" adapter (often called OTG or On-The-Go). This converts the small oval port on modern Android phones and iPhone into the classic rectangular USB port that most cheap gadgets use.
