Description:

The expensive power supply is a thing of the past!

Whitenergy offers the highest quality dedicated laptop replacement power supplies, available on our market. The massive housing of the Whitenergy power supply contains conceivable components that you will not find in cheap counterparts. Poor quality replacements are particularly dangerous for your laptop, because to reduce production costs, they are created from very low quality components. A common practice among suppliers of cheap replacements is the regeneration of components (ie refreshing old components). By purchasing our power supplies you can be sure that each element of the power supply is brand new.

Whitenergy power supply is 100% compatible with the original power supply, built from identical components, which gives you confidence that you use the highest quality equipment that will ensure the security of your laptop. The prices of originals reach even PLN 600 and it is a considerable expense. Thanks to our replacements, you can be sure that by paying a fraction of this price, you get an equally high-quality product.

The weight of the power supply first of all
The image presented below indicates the difference between the standard power supply and the Whitenergy brand. At first glance, you can see that our power supply is made of very high quality components, equipped with a greater number of electronic components, including copper-ferrite chokes, filters and screens. Thanks to this, as one of the few on the market, they meet the restrictive standards of EMC, LVD, RoHS2 – they do not interfere with electrical devices and do not suffer such disturbances. They also have surge protection from the mains and overcharging. This is why the Whitenergy power supplies weigh by min. 20% more than cheap replacements.

The Whitenergy power supply range is a wide range of products, the compatibility of which covers 99% of notebook models on the market.

Power cords
When buying a power supply, it is worth paying attention to the cables connected to the device. The Whitenergy power supply has a high quality cable in the set, along with a ferrite filter and a band, making it easier to roll up the cable. An additional advantage of the power supplies is a long cable, which will ensure the freedom of use of the laptop, even in conditions of difficult access to the socket. The length of the power cable (from the socket to the power supply) is approx. 1.5 m, and the length of the cable from the power supply to your laptop is 1.8 m. The total length of the cable is over 3 m! Whitenergy power supplies are the best power alternative for your laptop!

Equipment insurance
To protect your equipment and give you confidence in the high quality of our replacement, buying a Whitenergy power supply, you get insurance up to 10,000 Euro. This means that if our power supply in any way will damage your valuable equipment, we will refund your money in the amount of the equipment, up to a maximum of EUR 10,000. We guarantee that our product is 100% safe and designed in accordance with the highest EMC standards applicable on the European market, which is why we are able to offer such insurance that can not be provided by the manufacturer, who sells cheap and low-quality alternatives.
