Trata-se de um router económico (abaixo dos 35 euros), que recomendamos vivamente para expansão de uma rede Wifi.
Este equipamento compete com equipamentos de marcas conhecidas, como a TP-Link e ASUS que rondam os 80€, mas por menos de metade.
A configuração do mesmo é muito básico, não necessitando de grandes conhecimentos na área, podendo ser feita via Web (na rede), ou via App (android ou IOS) Mi Wi-Fi.
O GPD Pocket é um micro portátil da Marca Chinesa GPD, criado através de crowdfunding. O hardware é razoável para o tamanho, sendo que o preço pode ser discutível. Funciona muito bem com o Microsoft Windows 10, mas também suporta a distribuição de Linux Ubunto.
Testamos este dispositivo com o Antutu Benchmark e o Disk Benchmark para Windows 10. Veja os resultados…

A) Connect the red wire to the dead battery > positive terminal (+)
B) Connect the red wire to the live battery > positive terminal (+)
C)Connect the black wire to the live battery > negative terminal (-)
D)Connect the other end of the negative (black) cable to a clean, unpainted metal surface (such as the engine block) on the engine of the disabled vehicle. Try to find a spot on the engine far from the battery, as this connection might cause some sparks.
Let it idle for 5 minutes.
If it won’t start, wait another 5 minutes and try again. If it still won’t start, check to see if there are other problems, such as a lack of fuel. Do not keep trying to start the dead car, as you might cause additional damage.
Remove the jumper cables in the reverse order in which you attached them. Do not let the cables fall into the engine or allow any part of the cables to touch.
ORDER: D, C, B, A
Keep the newly jump-started car running for at least 30 minutes to make sure the battery recharges fully.

This is a personal test for 5 different power banks that I buy:
This test here all done with:
I’ve tested 5 different power banks, 4 of them Chinese (ROMOSS Sense 9, TP-LINK TL-PB15600, EC Technology PB-EC001, and a simple powerbank with a 18650 battery) and one german (MediaRange MR751). All were tested with the same KCX-017 USB meter and add the amount of 20 mA per hour of consumption in my measures.
When I was charging I use the KCX-017 to measure the Voltage and the current of the circuit with the same AC/DC power adapter that can give 5V 3A.

I’ve measured the time and the TOP power provided when I’ve charge the power banks and here is the results:



In this table I add 20mAh for the meter.



Power = Max(V*A)

Charging with a 5V, 3A (max) USB power adapter.
Power = Max(V*A)
The most efficient was the one with the highest capacity with almost 66% of efficiency (ROMOSS Sense 9). Meanwhile, the one who charges faster the equipment that it is plugged and charges faster it (capacity vs time) is the TP-LINK TL-PB15600 who makes the winner of these tests.


The RDP (Remote Desktop Protocol Connection) is not a feature of Home Edition. It is only enabled on Microsoft Windows 8.1 or 10 Professional or superior. But you can enable it with a third party application that is very easy to install.

O aeroporto da Portela resolveu criar um novo sistema de bases de dados. Para tal começou por organizar a informação sobre os aviões que “frequentam” o aeroporto.

This is my second review 🙂
This two portable bluetooth carkit are very similar, but the NEO 2 has more features but it will cost more… In my opinion this two are a very good devices 😉
