I have a Digitek UPS and the problem is each time the power goes out it takes a while before it comes back on even after the power is back. Could it be overheating? How can I rectify such a problem?

I need someone to give me a quick rundown on how to compute how much power my laptop charger draws from the mains whenever I charge my laptop. I am suspecting that my laptop charger consume too much power and I am not sure why. The charger can get very hot most of the time and electricity bills seem to be in the roof. Does a faulty laptop charger consume lots of power and if so why? Do older laptop chargers consume more than newer laptop chargers?

Which brand stands tall in the building of Universal Power Supply also known as UPS in the world? I am a student and a young businessperson who operates a Internet Cafe and I am currently living in one of the West African Countries. Because of what I do, I constantly need power supply in running my business even though I do have a standby generator I cannot constantly be buying fuel because of the price increase. I decided to opt for UPS that can prolongs my services for some hours to cut down the use of fuel. I have used a lot of brands when it comes to UPS because of the abrupt cut of power supply in my county. However, I am in search for the best brand that can service me at least ten to twelve hours of power supply. Thank you.
