Sometimes labeled on the cable as P7, the Berg connector is a power connection developed by Berg Electronics. It is used with computer power supplies that connect to floppy disk drives, front panel lights, and reset or turbo buttons. What … Continue reading →

Can you run a PC from a car battery? If you want to power your PC with a car battery then you should connect it externally. Either get a power inverter that converts 12V DC to 120V AC (easy to … Continue reading →

First and foremost, the vast majority of transformers are used in AC applications. On the output side of the transformer, there is no specific “positive” wire or terminal, because its “positive” only half the time. Which wire on a transformer … Continue reading →

A transformer is not designed to convert AC to DC or DC to AC. The transformer can step-up or step -down current. A transformer that increases the voltage from the primary to secondary is called a step-up transformer. The step-down … Continue reading →

DC-DC converters are high-frequency power conversion circuits that use high-frequency switching and inductors, transformers, and capacitors to smooth out switching noise into regulated DC voltages. Closed feedback loops maintain constant voltage output even when changing input voltages and output currents. … Continue reading →

Level 3 charging stations, or DC Fast Chargers, are primarily used in commercial and industrial settings, as they are usually prohibitively expensive and require specialized and powerful equipment to operate. This means that DC Fast Chargers are not available for … Continue reading →

In order for current to increase when voltage drops, the circuit resistance R must decrease by more than the voltage. With a lower voltage to do the same amount of work (W) the amps(current) will go up. A 100W 220 … Continue reading →

If the CPU usage is around 100%, this means that your computer is trying to do more work than it has the capacity for. This is usually OK, but it means that programs may slow down a little. Computers tend … Continue reading →

5v definition (5 Volts) A standard voltage required by chips and drives in a computer. The power supply converts 120v alternating current (AC) into 5 volts of direct current (DC), as well as 3.3v and 12v. What does 5V output … Continue reading →

The good news is that even though failing to restart your phone periodically could zap memory and cause crashes, it won’t directly kill your battery. What could kill your battery is always rushing to recharge. Is restarting your phone bad? … Continue reading →

SATA power cables protrude from the power supply unit and are meant to reside only inside the computer case. This is unlike SATA data cables, which are also usually kept behind the case but can also connect to external SATA … Continue reading →

Can I wire an outlet to a 12V battery? No. 12V DC (battery) is a very different kind of power than 230V (or 110V) AC. You can’t directly connect the two. What can I plug into my car outlet? Ford … Continue reading →

Typical Charger Power Usage Current equals wattage divided by voltage, so the average phone charger is drawing 0.3 amps from a 12-volt battery. How much power does a 12 volt battery charger use? Most battery manufacturers recommend sizing the charger … Continue reading →

Charge the UPS battery, by plugging the UPS into the AC mains wall socket and leave it charging for at least 12 hours. This will give the UPS battery an excellent start in it’s service for you. How do I … Continue reading →

When you plug a keyboard in it, for example, it will be powered up but since the data lines aren’t connected anywhere, the signals it sends won’t be read. It would be the same if you plugged it into a … Continue reading →
