A brief review of the BURO BUM-1127H70 70W universal power supply for laptops

Universal power supply for laptops BURO BUM-1127H70

Today we have a review of a universal power supply for laptops from BURO, model BUM-1127H70 for 70 watts. This model is designed to power laptops and other mobile devices, the supply voltage of which is in the range of 12 – 20 V and is equipped with a manual output voltage switch.

The kit has everything you need – the power supply itself, a cord for connecting to a 220 V network (110 – 240 V range is supported), a set of adapter connectors and an instruction manual.

The characteristics of the power supply are indicated on the sticker on the power supply itself.

The instruction in Russian combines the description of several models of power supplies and several types of adapter connectors.

The kit includes 11 adapter plugs, among which there are connectors for laptops of popular companies: HP, Lenovo, Acer, etc. I was pleased with the presence of a more “standard” 5.5×2.5 mm connector, suitable for powering, for example, CCTV cameras, DVRs, routers , flatbed scanners, etc. The plug contacts, as well as the holes in the power supply socket, have different diameters, which eliminates the possibility of incorrect connection.

On the body of the power supply there is a green LED indicator, the manufacturer’s logo is applied, as well as the values ​​\u200b\u200bof the supply voltages that can be set. The switch slider is hidden under a silicone strip on the side of the power supply, apparently to protect against accidental switching, as well as to protect against dust.

The places where the voltage values ​​are applied do not coincide with the position of the slider, therefore, one can only guess what voltage is currently set. Or, by moving the slider to one of the sides to the end, then set the desired value. This must be done, of course, by disconnecting the power supply from the network.
