Whitenergy offers the highest quality dedicated replacement power supplies for laptops, available on our market. The massive housing of the Whitenergy power supply hides 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 substitutes is the regeneration of components (i.e. refreshing old components). By buying our power supplies you can be sure that each element of the power supply is brand new.
The Whitenergy power supply is 100% compatible with the original power supply, built with the same components, so you can be confident that you are using the highest quality equipment that will keep your laptop safe. The prices of the originals reach up to PLN 600 and this is a considerable expense. Thanks to our substitutes , you can be sure that by paying a fraction of this price, you get an equally quality product.
The picture presented below shows the difference between a standard power supply and a Whitenergy brand. At first glance, you can see that our power supply is made of very high quality components, equipped with a larger number of electronic parts, including copper-ferrite chokes, filters and screens. Thanks to this, as one of the few on the market, they meet the restrictive EMC, LVD, RoHS2 standards - they do not cause interference with electrical devices and are not subject to such interference themselves. They also have protection against overvoltages from the electrical network and overcharging. This is why Whitenergy power supplies weigh by min. 20% more than cheap substitutes.
When buying a power supply, it is worth paying attention to the cables included with the device. The Whitenergy power supply comes with a high-quality cable, along with a ferrite filter and a band for easy cable rolling. An additional advantage of dedicated power supplies is a long cable that will ensure the freedom of use of the laptop, even in conditions of difficult access to the outlet. The length of the power cable (from the socket to the power supply) is approx. 1.5m, and the length of the cable running from the power supply to your laptop is 1.8m. The total length of the cable is over 3m! Whitenergy power adapters are the best power alternative for your laptop!
To protect your equipment and give you confidence in the high quality of our replacement, when you buy a Whitenergy power supply, you get insurance up to 10,000 Euro. This means that if our power supply causes damage to your valuable equipment in any way, we will refund you the amount of the value of the equipment, up to a maximum of 10,000 Euro. We guarantee that our product is 100 % safe and designed in accordance with the highest EMC standards applicable on the European market, Therefore, we are able to offer such insurance, which cannot be provided by a manufacturer selling cheap and low-quality substitutes.
- Mains filters and circuits to reduce current surge during power supply start-up.
- Rectifier system.
