Coffee pots

For lovers of an invigorating drink, quite effective devices have been invented that function without electricity or a kitchen burner. You can take a metal French press or a coffee maker of a different design with you.
For example, it can be devices powered by a tourist gas cylinder, such as the famous Coleman QuikPot.
Flashlights and smart bulbs with USB output

In fact, these are the same power banks. It’s just that now manufacturers of “camping” devices with built-in batteries began to supply them with an additional board and a 5-volt port for charging gadgets via USB.
As a fallback “emergency” solution – quite a good option. We carry batteries inside our flashlights anyway, so why not have full access to them when needed.
Solar panels

Photovoltaics has proven itself perfectly on long hikes, when batteries and rechargeable batteries may still not be enough. Portable panels can be integrated into electronic devices and objects (for example, there is a solar refrigerator, oven, table).
They can also be used as a stand-alone, portable fold-out module.
Photovoltaic panels work well with power banks to collect precious energy throughout the day. Sometimes the “buffer” battery is part of the solar module.
It should be borne in mind that the efficiency of solar charging is highly dependent on the weather, season and climatic zone. It can be very difficult to achieve the indicators indicated in the characteristics, especially if the panel is operated on the go (on a backpack, in a boat, or even on the back of a camel).
Smart tent

In addition to its main purpose, the Orange Solar Tent is able to accumulate solar energy during the day using photovoltaic cells that are part of its frame. The resulting current can be used to illuminate the “home” in the dark or to charge gadgets.
Also, this device has an integrated geolocator to help navigate the terrain.
Compact hydro turbines and wind turbines

The producers went their separate ways. Some companies have relied on a variety of sails.
Others use a miniature turbine. It is driven by a fan-like structure.
Still others made a smaller analogue of a three-blade wind turbine and equipped their 50-watt device (weighing 650 grams) with a built-in 7500 mAh battery.
Stoves that deliver current during operation

A tourist does not always have the right amount of sun, wind or river flow. But without fires or gas / alcohol burners, business is not complete. It was decided to use thermal energy, which we release anyway. This is how the FlameStower type devices appeared, which generate current due to the thermoelectric effect.
It is enough to direct the tongues of flame onto the metal plate, and then pour some water into a small reservoir – and you can slowly charge the gadgets while the camping pot boils.
Different types of wood chips work according to the same principle, which are supplied with built-in Peltier elements.
Muscle power generators

Well, why not. This energy source is perhaps the most reliable and most renewable. Previously, such devices, due to their low efficiency, seemed to be something frivolous. Now the topic of the so-called “hand turbine power” has sharply become relevant: they are able to give the smartphone battery those missing percentages that are necessary to make a salutary call in every sense. You only need to turn the handle vigorously for a few minutes.
With the manual recharge option, we don’t lose anything even in terms of excess weight. After all, “dynamo” is often an element of a power bank, which almost all tourists take with them anyway. Above, we wrote about portable turbines that can be powered by wind and water. So, you can unwind them with your hands.
Segway for off-road

This type of electric transport used to be considered an attribute of purely urban life, but not so long ago, Segway-SUVs, which go well over rough terrain, have become popular. They are endowed with more powerful motors and grippy 19-inch wheels. Their complete lithium batteries provide a range of up to 35 kilometers. The devices deliver speeds of up to 20 kilometers per hour and have a carrying capacity of over 140 kilograms. On such a device for the whole day, you can safely travel around all the surroundings.
The solution turned out to be so successful that even the military, who are actively introducing segways for combat and rescue operations, became interested in it. And these guys know a lot about efficiency.
