Xiaomi Mi Router 3 vs Xiaomi Mi Router 4

A Xiaomi recentemente colocou à venda o seu novo router Xiaomi Mi router 4, que vem substituir o seu famoso Mi router 3. O que há de novo? Vale a pena fazer o upgrade? É uma boa compra?

Xiaomi-logoDepende… Se não tens um Mi Router 3 e queres um novo router, ou um wireless ou wired repeater, sim, é uma boa opção, não existindo um equipamento tão interessante (relação qualidade/preço) no mercado.

Se já tens um Mi Router 3 e estás a pensar em fazer um upgrade, a reposta depende da tua estrutura de rede.

Um Router económico e excelente para ampliar o sinal Wifi por menos de 35 euros

Xiaomi Mi Router 3

mi router 3Trata-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.

GPD Pocket – Características e teste de desempenho

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…

Jump-start your battery car with other car (Quick guide)

jump start

1. Turn off your boosted car and connect the wires

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.

2. Start the booster car.

Let it idle for 5 minutes.

3. Try to start the car with the dead battery

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.

4. Once the dead car does start

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.

Power Bank benchmarks

This is a personal test for 5 different power banks that I buy:No brand 2200mA power bank

  • ROMOSS Sense 9 25000mA;
  • TP-LINK TL-PB15600 15600mA;
  • EC Technology PB-EC001 16000mA;
  • MediaRange MR751 5200mA;
  • No brand 2200mA.

This test here all done with:KCX-017 USB Power Meter

  • To meter the consumption I use a power meter KCX-017;
  • For charging Charger 5V, 3A;
  • For discharging I use a tablet Chuwi Hi10Pro (Android and Windows 10 tablet) that charges with a USB charging (playing YouTube HD/Full HD videos to drain the battery).

CHUWI Hi10 ProI’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.

Testing PowerBanks

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

Final results and opinion:

romoss sense 9 power bankThe 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.
