LED - The Future Of Lighting

LED - The Future Of Lighting

LED bulbs are undoubtedly the biggest breakthrough in lighting in the last 50 years. They are much more efficient compared to older technologies such as Incandescent and Halogen and they have a lifespan of over 50,000 hours.

Traditional light bulbs work by passing an electric current through an extremely thin filament which becomes very hot and emits light. The problem with this is that 90% of the electricity is wasted as heat so the traditional light bulb isn't very efficient. LED bulbs have numerous Light Emitting Diodes that produce light when a current is passed through them. The current excites the electrons inside the diode and produces light. They are much more energy efficient because they only need a small current to emit light. The LED doesn't need to get hot to produce any light so they need just 10% of the energy a traditional light bulb needs.

So how much money could you save by switching to LED? Well, if you swopped a 50 watt halogen bulb with a

The dangers of buying an original charger

One of the most common questions we get at Power4laptops is "Do you sell original chargers?". We don't sell the original ones for a couple of reasons.

The first thing is the cost. Even at the cheaper end, the original brand chargers tend to retail about £40 - £50 which is way more expensive than our own Power4Laptops chargers.

The second reason is the market is absolutely flooded with fake counterfeit chargers. These chargers will look exactly like your original one, but these fake chargers don't meet UK safety regulations and can lead to fires and electric shocks. So we didn't want to have to compete against someone selling a so called original brand charger for £7.99 on eBay or Amazon when in reality the charger they are selling is fake.

On the outside, the differences between a fake charger and a genuine charger are getting harder to spot as the counterfeiters use better techniques. The real difference is on the inside. Ch

How to buy a Laptop Charger

At Power4Laptops we have a massive range of chargers on the site. At the last count we had chargers to fit over 129,000 models of laptop. But what if you can't find your model of laptop on the site?

The easiest way to help us find your charger is to fill in the Help Finding a Charger form. The form just asks for some details about your laptop, such as Manufacturer, Model, Input Voltage, Input Amperage.

Most of the information can be found on the label underneath the laptop, often in really small writing. The Input Voltage will read something like **V e.g 19V. The Input Amperage will be something like ***A e.g 3.42A. On HP laptops this information can be sometimes found underneath the battery compartment.

After you have filled in the form we will normally contact you the next business day with a link to a listing so you can buy the correct charger straight
