Completeness and general design of the Porto PAD100 power supply unit.

The Porto PAD100 power supply kit includes: a cord with an AC plug, a cord with a plug for connecting to a 12V car socket (cigarette lighter socket), and a bracket with eight different types of connectors for connecting laptops, netbooks, and other portable devices.

Connectors compatible: 2.5&# 215; 0.7 mm Asus eeePC, 4.8&# 215; 1.7 mm Asus eeePC, Acer, LG, HP / Compaq, 5.5&# 215; 1.7 mm Acer, Dell mini, 5.5&# 215; 2.1 mm Acer, 5.5&# 215; 2.5 mm Asus, Acer, IBM / Lenovo, Toshiba, Fujitsu-Siemens, Dell, MSI, Packard Bell, 5.5&# 215; 3.0 mm Samsung, 6.3&# 215; 3.0 mm Toshiba, 6.5&# 215; 4.4 mm with needle inside Sony, Fujitsu-Siemens, Panasonic.

Porto PAD100 has an integrated load correction circuit, which allows you to connect devices with different capacities to it and provide high efficiency (more than 80%). The unit is equipped with protections: input and output voltage. Over current and voltage overload. From short circuits. From high frequency interference on the network. From overheating. All this makes his work safe..

The metal housing of the Porto PAD100 with a degree of protection against dust and moisture IP20 provides good cooling of the power supply during its operation at high loads. Class of protection against electric shock Class II. From one end of the block housing are connectors for connecting power cords from a DC or AC network. On the other hand, an output voltage switch and a USB connector with an output of up to 1 ampere, for charging devices powered by USB.

Connection and operation of Porto PAD100 universal laptop power supply.

Before you connect and use Porto PAD100, you need to make sure that it is compatible and suitable for your portable device, otherwise the consequences can be very sad. From simple inoperability to failure of your laptop, netbook or other device. For this.

1. We select the appropriate connector from the Porto PAD100 kit and check its compatibility with the power connector of your device.

2. We look at the magnitude of the voltage and current consumed by your device, they are usually indicated on the bottom of the case. For example, for a Lenovo G550 laptop, these numbers will be as in the photo below, the input voltage is 19 V, the input current is 3.42 A. The value of the input current of the device must be equal to or lower than the output current Porto PAD100 for 19 volts in this case 3.42 less 5.0 A, then it’s suitable. The voltage value must be equal both in the device and in Porto PAD100.

3. You should also take into account the power of your device in watts, which is determined by simply multiplying the current strength by voltage. It should be less than or equal to the power of the power supply. In our case: 19×3.42 = 64.98 watts, which is less power Porto PAD100 (100 watts) means suitable.

We figured out the theory, now we can proceed to practice. We connect the selected connector to the Porto PAD100 output cord with a ferrite filter, there is no need to worry, the positive terminal of the connector is thicker than the negative one, so there is no way to make a mistake. Then we connect the power supply to the AC or DC network. Set the desired voltage with the switch, which will be indicated by a glowing green LED, and insert the connector into the device’s power connector.

The necessary derogation is an addition to the cigarette lighter and its purpose in the car.

The cigarette lighter of the car itself is a mechanism and the fact that it is used as a socket is not entirely correct. Although for many he copes with this function. The fact is that all the more or less powerful portable electronic devices are designed to connect them to special 12-volt car sockets, and not to the cigarette lighter socket, although in most descriptions of the devices it is for some reason that it is mentioned. On some cars, in addition to conventional cigarette lighters, a separate special outlet is already initially present, for example, with the inscription 12V, 120W, it is it that is designed to connect all non-standard electronic devices and devices.

If there is no separate outlet, then as an option, you can first connect a splitter for several outputs to the cigarette lighter socket, there are a lot of them on sale now, and connect power supplies and devices to its sockets. However, everything will be fine only until the splitter starts to melt. In the best case, a penny fuse, which is easy to replace, will burn from a short circuit. In the worst case, the car wiring will become unusable or the connected electronic device will fail. This happens because the wiring of most cigarette lighter splitters is designed only for low-power consumers, but not for one or more powerful devices such as a laptop.

And it’s good if the manufacturer indicates in the characteristics of the splitter what power it is designed for, since otherwise you have to rely only on a good combination of circumstances. The same goes for a regular car cigarette lighter. Yes, it is designed to work with greater amperage, but only for short-term, but long-term power supply from it of powerful devices and devices can lead to fuse blowing, fusion of the surrounding plastic and, as a result, to a fire. That is why it is advisable to install a separate special 12V socket in the machine with powerful wiring directly from the battery and a separate fuse.

In conclusion, on power supplies for laptops similar in design to the Porto PAD100 unit.

Power supplies similar in design to the Porto PAD100 are gradually losing popularity and are being phased out. Very much they turn out specialized. Now, at almost the same price, you can purchase more versatile automotive inverters, converters 12V-220V. They have a power outlet is a regular household outlet. This allows you to directly connect all the necessary devices and devices designed for 220 volts. As for this Porto PAD100 directly, its purpose at the moment is to serve as a backup in case of failure of the main regular laptop power supply. Or, if necessary, provide charging and operation of different laptop models in the field from the vehicle’s on-board network.
