How can I extend the battery life of my laptop?
Just follow these 5 steps:
  1. Avoid short charging times as the battery in our device has the number of charging times specified by the manufacturer.
  2. Use batteries. Our rechargeable battery is designed for use. Continuous removal of the battery from the device does not have a positive effect on its condition.
  3. Do not allow full discharge. Today's lithium-ion and lithium-polymer batteries are extremely sensitive to deep discharge. Repeated repetition of such a situation can cause irreversible damage to the battery.
  4. Pay attention to the operating temperature. Temperature is an extremely important factor affecting the life of our battery. To ensure optimal temperatures, you should regularly clean your laptop's heat-dissipation system (with compressed air or a compressor) and avoid using the devices on soft surfaces (which can obstruct cooling vents).
  5. Let the battery rest. If you plan to take a long break from using your laptop, remove the battery and place it in a dry, cool place. It is worth loading it to about 50% to avoid a complete discharge.

Which inverter for power tools?
The most important aspect when selecting the inverter is to determine the maximum power of the connected device. If you want to use the inverter permanently, you should use a maximum of 90% of its continuous power. Let's use a simple example to illustrate this: If you use an inverter with a power of 1000 W, the maximum power consumption of the connected device should not exceed 900 W.
Which inverter for a car?
In a car you will find a 12 volt cigarette lighter socket and such inverters are the best to buy.
How does an inverter work?
An inverter is a standalone device that plugs into the cigarette lighter socket or directly into the battery. Its task is to convert the 12V/24V voltage from the car's DC system into 230V AC. For this reason, you will very often find the following abbreviation next to the name of the inverter: DC/AC.
What types of inverters are there?
When it comes to automotive inverters, we can distinguish two main types: pure and modified sine wave inverters. The first is intended for devices that require a continuous power supply. This type of inverter should be chosen for devices such as heat pumps, electric cookers or electronic kettles. Our shop also offers modified sine wave inverters. This type of inverter is suitable for devices such as laptops, power supplies or lighting.

What is energy storage and what is it used for?
Energy storage can be compared to a powerful battery for the whole house, which stores the electricity produced by photovoltaics when there is too much and returns it when we need it.
What energy storage options are there?
There are currently five ways to store electricity:
mechanical (with compressed air reservoir)
electromechanical (batteries and rechargeable batteries)
chemical (production of hydrogen or methane)
electric (supercapacitors)
thermal (accumulation of sensible or latent heat)
The most famous form of energy storage are electromechanical solutions such as batteries/accumulators. GC PowerNest is just such a solution. At the heart of the device are LiFePO4 (Lithium Iron Phosphate or LFP) cells, which have more than ten times the life and twice the depth of discharge (100% - 0%) of traditional acid batteries while being much safer and more durable than standard lithium-ion cells.
Thanks to the stability and safety of use of the GC PowerNest energy storage, the guarantee is up to 10 years or 15,000,000 Wh of energy worked.
