Breve Análise do Portátil Chuwi LapBook Air 14.1 (N3450, FHD)

Atraente e lento. O clone do MacBook Air da Chuwi certamente tem um bom visual e poderia passar facilmente como um Ultrabook do dobro do preço. Cave um pouco mais profundo, no entanto, e as pequenas falhas rapidamente começam a aparecer.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
29.2 ms ... rise ↗ and fall ↘ combined↗ 16 ms rise
↘ 13.2 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.1 (minimum) to 240 (maximum) ms. » 76 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (21 ms).
       Response Time 50% Grey to 80% Grey
32.8 ms ... rise ↗ and fall ↘ combined↗ 12.8 ms rise
↘ 20 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.165 (minimum) to 636 (maximum) ms. » 40 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (32.9 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM detected 200 Hz ≤ 20 % brightness setting

The display backlight flickers at 200 Hz (worst case, e.g., utilizing PWM) Flickering detected at a brightness setting of 20 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 200 Hz is relatively low, so sensitive users will likely notice flickering and experience eyestrain at the stated brightness setting and below.

In comparison: 53 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 8774 (minimum: 5 - maximum: 343500) Hz was measured.

In review: Chuwi LapBook Air 14.1. Test model provided by Chuwi

O LapBook Air se vê e se sente incrível considerando o baixo preço de $400. A tela IPS de 1080p é nítida, a opção de armazenamento interno secundária é rara e inclusive o teclado é iluminado. Infelizmente, o fabricante teve que fazer alguns cortes profundos em quase todos os outros lugares para atingir o preço impossivelmente baixo.

Para começar, a garantia de qualidade não está à altura das alternativas mais conhecidas. Nossa unidade de teste sofre de "bleeding" moderado da iluminação de fundo da tela, iluminação do teclado irregular, uma tecla Ctrl quebrada, uma porta USB defeituosa, falhas múltiplas e uma borda dobrada. Recomendamos que os novos proprietários testem cada porta e tecla para garantir que não haja nada danificado fisicamente. Em segundo lugar, o processador Celeron passivamente resfriado, o SSD primário e o carregador de CA são todos muito lentos. Os usuários que querem algo um pouco mais poderoso estariam melhor com um portátil ULV Haswell mais antigo que provavelmente terá teclas mais firmes e trackpads mais precisos. Se usado principalmente para streaming e reprodução de vídeos em movimento, no entanto, o LapBook Air não é ruim.

O LapBook deve ser útil para aqueles que planejam somente navegar na web, processamento de texto e transmissão de conteúdo de vídeo.
