How do I select the right power supply for my device?
The laptop model is usually located on the underside of the device. Read it and enter it into the shop's search engine.
e.g. Asus K53SV / HP Pavilion G6 / MacBook Pro 13 A1278
Value of INPUT / OUTPUT
On the power supply nameplate, the voltage and current values are marked OUTPUT, and on the bottom of the laptop, the same parameters as INPUT are marked. Read some of them and enter them into the shop's search engine by adding the brand of the device. Make sure that the plug of the power supply found is correct.
e.g. Asus 19V 4.74A / Dell 19.5V 4.62A / Lenovo 20V 3.25A.
I have a 65W power supply or can i use a 90W power supply?
With such small differences it is acceptable. However, we must remember to use power supplies with higher power, not less, because at lower power the laptop may not work.
Is this power supply suitable for my laptop?
It will be suitable for our laptop if the plug diameter meets the outer diameter specification, e.g. 5.5 mm, and the output parameters are compatible. What are output parameters? It is the value of voltage[V] and current[A] that is given by the power supply for a laptop, e.g. 19V 4.74A.
Charger for the laptop - which voltage is correct?
While choosing a new charger for your laptop, remember to double check the voltage level of the charger - this parameter should be exactly the same as the one on your original charger.
The power supply for a laptop is often a more exploited component than the computer itself. The charger is either rolled up at the bottom of the bag or lying on the floor while it is charging. That means the power adapter can get damaged not only from a fall when pulling it out of the bag but also from accidental kicking or stepping on it.
Fortunately, buying a new power adapter is a small cost, and the equipment you purchase will serve you for years to come. At Battery Empire you'll find a full range of power adapters for most computers, reducing the tedious search for a charger to just a few clicks.
The harbinger of an upcoming charger replacement will be your computer's notification: "Connected - not charging". This message could indicate that the power adapter is faulty. If you have the option, it's still worth checking that your laptop power adapter is working properly on other equipment of the same type. You can also replace the power cable with another one. If the message still appears it's clear and you'll need to look for a new charger.
Check the rating label on the back of the power adapter - the model designation is there. Now all you have to do is enter the model of the charger into the search engine on our shop's website. This will allow you to immediately find a charger that is compatible with your computer.
Occasionally you may not have an adapter on hand. In this situation, check the laptop's specifications, which manufacturers list on the inside underneath the battery. On your laptop's nameplate, you should look for the OUTPUT parameter, which is made up of voltage in volts and amperage in amps.
Multiply the volts and amps by each other to get the wattage in watts. Compare this result with the power supply of your choice. If you choose a more powerful one, your computer will be fine. The most important value is the voltage (V), this parameter may differ by only 1 V from the manufacturer's recommendation.
If you're in the UK, your laptop charger requires a different plug for UK sockets. You'll find this type of mains power cable in our shop.
All you need to do is match your Green Cell power supply with a UK plug. The chargers we sell operate in a range from 100 to 240 volts. So you can charge your computer in both the UK and Poland. All you need to do is change the cable to one with the correct plug.
Green Cell PRO series power supplies have a significantly longer lifespan than standard power supplies. While most of them offer a performance of 1 or 2 years, the Green Cell PRO laptop charger ensures trouble-free operation for more than 3 years. This means you don't have to worry about your power adapter for years to come, and the failure-free performance saves you money.
Even if your current power supply is performing well, but you take your computer to the office every day, it's worth getting a replacement. This way you don't have to remember to take your power supply with you to work. It will save your original laptop charger. Also, your laptop bag will become a little lighter.
The Green Cell PRO series laptop charger also features several short circuit protection features. The devices also provide you with overvoltage protection and thermal protection. That means the power supply won't overheat while charging, and you don't have to worry about damaging your computer during voltage spikes.
The Green Cell chargers allow you to work comfortably thanks to their total cable length of 2 metres. The durable construction ensures that the cables do not break at the point of connection with the power supply, even after repeated winding and unrolling of the cable. Made of high-quality materials, the cables are robust. So even if you run over them several times or screw them between the wheels of an office chair, they won't break.
