In the midst of the energy crisis, the government is trying to avoid the worst this winter: power cuts. To achieve this, there is either sobriety, or the use of an electric generator

Faced with the message that the government has been hammering for weeks, an electric generator would simply save the energy that can be saved…
What the media has called the energy “sobriety”.
The government alerts and seeks at all costs to avoid power cuts this winter.
In the middle of the energy crisis, the French are wondering how to avoid this risk which is becoming so real…

A real economy of each could avoid cuts at the end of the year assures the head of the State…

But since the risk is real, there are other solutions available to us.

Use an electric generator to reduce consumption from the electricity network

An electric generator is composed:

  • a portable charging unit, a kind of large electric battery that will play the role of energy storage
  • foldable and portable solar panels which once unfolded and connected to your external battery will allow the charge of your external solar portable battery.

The external battery is an accumulator that will allow you to charge or power everything in case of power outage.

Its “mobile” use is also perfect during all your travels or activities “Outdoor” or on isolated sites not electrified.
It has all the plugs to charge your electronics in nomadism (USB-A, USB-C, 12V cigar lighter) like smartphones, cameras, drones, laptops, lamps etc…
Plus, it also integrates classic AC sockets (220V mains socket) in order to connect classic electrical appliances such as TVs, lamps, PCs, fans etc…

The solar panel is the “alternative” charging instrument of these electric generators; in fact, the electric group is charged both on the mains and via the solar panels (which gives you autonomy in the event of a power cut).

By using 100W or 200W panels, you recharge the electric generator in an acceptable time which gives you the desired autonomy.

An ecological (renewable energy) and silent solution that allows you to free yourself from network outages

A solar electric generator is thus a perennial and very interesting solution for energy autonomy.

The battery using the latest LiFePo4 technology allows for 2500 to 3000 charges vs 500 charges for competing batteries that use traditional LiPo.
The latest generation of high efficiency mono-crystalline solar panels will also work for 10 years and more…

Add to that the fact that you have autonomous energy needs because you practice camping, outdoor, have a remote site not electrified and other lifestyle in nature (#Vanlife) …

Then this solar electric generator is perfect for your needs.
All you have to do is choose the capacity/power of the battery you want according to the devices you want to charge/power: 600W, 700W or 1000W are currently on sale on the Powertec website.

There are other even more powerful solutions that play the role of ESS (Energy Storage System) generators that allow us to guarantee the power supply of our home if there is a power outage, just like the UPS (Uninterruptable Power Supply) system that ensures the power supply of users.

The backpack is the necessary accessory for any hike…
To have your hands free when moving on uneven terrain, when sliding, when climbing, when hiking is an obvious choice.

The backpack has made its mark on the outdoor world

Its usefulness has been proven.
Its size and its bedding have been adapted in all sorts of ways.
The way it is attached, the number of straps, the number of pockets, its waterproofness, its weight, all these parameters have been adapted in all forms.

Moreover, it is difficult to ask a real outdoor man to change his old backpack. This companion is part of adventures and it is often very complicated to make the experienced adventurer change his bag.

Some people decorate their backpacks with stickers, badges of the countries they have visited and the adventures they have had. The backpack thus becomes the living memory of the traveller.

The backpack has also become a lifestyle product

Because it is also practical, it was necessary to add a layer of elegance to the “Outdoor” backpack in order to make it part of everyday life.

In the 80’s, the famous “US Bag” appeared and was a real hit with students. Easily found in army surplus, this khaki bag also became a territory of unlimited expression for its owner who personalised it with rock bands, poems, quotes etc…

Having become an obvious object for all schoolchildren, several rather technical brands of luggage or “outdoor” objects follow suit by introducing trendy colours and ever more interesting materials…

The eco-friendly backpack in the 2000s.

It wasn’t until the 2000s that environmental awareness got the better of overconsumption that upcycled products (recycled materials) emerged, or products made mainly from plastic bottles.

This is the case of the Ticket To The Moon backpacks, which from the end of the 90s are made with the scraps of the hammocks of the homonymous brand. The desire to produce beautiful, colourful, resistant bags (made of nylon silk – an indestructible material used to produce parachutes) and hand-sewn to complete a guarantee of quality.

All Drones users know The Fly More Kit which optimizes the use of the DJI Mavic 2 drone!






This kit which includes a whole series of essential accessories for extensive outdoor us. Namely 2 DJI Mavic 2 batteries, a cigar lighter socket  and a charging station (allowing you to recharge several batteries in a row).

If the cigar lighter charger provided in the Fly More DJI Mavic 2 kit allows charging from the cigar lighter socket of your vehicle, it is also the essential accessory to use your DJI Mavic Drone in complete autonomy by charging it from the Solar charging station powered by Powertec.

Mont Logan Expedition










Indeed, from the 16W Tactic Pack imagined by Powertec, we have a portable battery storage unit , 30.000mA / h @ 4.5A max and allowing the recharging in particular of all electronic devices that have a 12V charging system by car cigar lighter socket.
The PT111 battery can be recharged via any 12V Powertec solar panels:
– PT16Flap Duam Output (5V & 12V) solar charger
– or by our latest PT21 USB-C   Tri Output panel (we have added a nativ USB-C, 3Amp @ 5V  to the existing 5V and 12V .
With these 2 panels, you can load your 12V batteries in 6 to 7 hours.
The battery will thus constitute a reserve of energy to charge or power your DJI Mavic Drones batteries.








The “pass-through” system here takes on its full meaning for a solar charging station: the solar panel charges the Powertec battery which recharges the Mavic batteries.

The latest fully autonomous expeditions have benefited from this technology in order to be able to power their drones during their journey which lasted more than 40 days in total autonomy.
The drone, which has become an effective means of reconnaissance to trace its route in perilous places such as glaciers or rugged trails, thus becomes an object of comfort and safety beyond taking photos and videos which it is difficult to do without.
Thus, Powertec who proudly celebrated its 12th anniversary a few months ago, has established itself in the very competitive market for solar solutions.
Its uniqueness in offering its solar charging solutions makes it the specialist in DJI Mavic Drone charging by portable solar solution.

We accompany several major expeditions each year in their conquest of new spaces, and allows them to face these new adventures in complete safety.

Since it arrived on the first smartphones a few years ago, USB-C has been gaining ground. We can see it on all our electronic devices and it is slowly becoming the connectivity standard of tomorrow.
But if USB-C is first and foremost a design, i.e. a connector that can be plugged in any direction (phew!), what about its characteristics and why do all the manufacturers keep on boasting about the integration of this standard in their new electronic products?

USB-C or USB Type-C, is first of all a standard relating to the cable connector, which differs from the USB-A, microUSB and Lightin connectors that we knew until now, and that we found on many Android smartphones and iPhone.

Like its cousins, a USB-C port can be used to charge devices, exchange data, and even transmit audio and video streams.
It is finally through these last uses that USB-C finds its universality.

But what interests us here is that USB-C is, like other USB standards, made to charge.
USB-C offers several energy profiles. While the classic USB operated in 5V, then in 5.2V then in 3.7V only allowed 2.5 Watts then 5Watts of power, the Type-C offers a minimum of 10 Watts (which explains the new standards of smartphone Fast charge) and a maximum of 100 Watts, which allows the charging of a computer.

Powertec has been working since 2016 on this new standard which opens a small revolution, both in terms of charging and connectivity and products to charge.
In order to develop a USB-C ecosystem, the R&D of the first USB-C solar charger has just been completed with a market launch in 2021.
To accompany it, a series of new USB-C accessories to charge everything quickly, including:

(5V / 3A)

, microUSB+ USB-C + Lightin

integrating USB-C in/out charging

Thus equipped, the next USB-C solar panel + its accessories will provide you with all the comfort of a light, robust and fast mobile charge!

Have a nice trip !

Hiking equipment will no longer be a secret for you.

Summer is the right time to go for a walk in the nature to work on your endurance or to recharge your batteries in the heart of the most beautiful landscapes of France or any other country. Alone, with family or friends, hiking, trekking, trail, etc. with several nights should not be prepared lightly, especially if you do not sleep in a refuge. In this article, you will discover the hiking equipment necessary for your survival, your safety and your comfort for an autonomous hike.

Think first about the hiking food

The first thing to think about when hiking is food and water. Take something to eat, including dehydrated food and cereal bars, but also utensils (plates, cutlery, multipurpose knife, cup, etc.). To heat your supplies or simply to warm up, the flint (also called fire starter) will be perfect to light a fire easily with small wood and a knife..

Stay hydrated with an insulated water bottle to keep the water cool or a filter bottle. Worried about running out of water? Pack a water treatment solution for your reusable bottle.

The hiking clothes to choose

Hiking clothes are important, especially to protect yourself from cold or insects. It must be comfortable, waterproof and adapted to all weather conditions as well as to hiking: jacket, pants, socks, shoes, hat, sunglasses, etc. Think also of breathable T-shirts that allow to evacuate perspiration. To stay warm, opt for thermal clothing, a fleece, a hat, gloves, etc..

A well organized hiking bivouac

The backpacking camp will be the place to relax and survive after a long day of hiking. Here is the equipment for your camp:

– Small tent,
– Sleeping bag adapted to the outside temperature,
– Self-inflating mattress,
Waterproof headlamp and/or rechargeable flashlight,
– Survival blanket,
– Protection against insects (for example a mosquito net).

We also advise you to bring a portable charger to install in your bivouac which can take the form of a foldable solar panel. Thanks to this solar charger, you will be able to recharge your electronic devices quickly and easily, by USB cable.

Survival accessories to take with you

Sleeping in the wilderness can be a real survival, sometimes in a hostile environment. Therefore, it is sometimes necessary to bring a few survival items in your backpack such as an emergency whistle. For your orientation, use a compass and a map of the area where you are going. In case of a small or big injury, the health kit will not be too much for you.

Do not forget the electronic devices for hiking

Electronic devices are not left out and can be very useful like the hiking GPS or the GPS watch that you can recharge with an external portable powerbank battery itself charged with a usb solar charger.

Powertec offers all these quality products for your hikes with the only concern of allowing you to connect and charge all your devices for the greatest energy autonomy and in the greatest respect of the planet!
