Buy for the elapsed time display or skip for the backlit LCD

This is the second one I've bought just because I kinda lost the first one. I have other USB power meters, but this one has an elapsed time display, which is handy when I want to know how long it takes to charge or discharge a battery. Compared to other OLED meters, the backlit LCD has mediocre contrast and the backlighting at the bottom of the display is noticeable, which isn't very good. For some reason the display font here is different from the product photos, I uploaded a photo. Aโ€ฆ

Pros
  • Rugged construction
Cons
  • Legacy model

Ideal for testing the battery capacity of the phone.

My phone was a few years old and I suspected that the battery had lost some of its capacity. So I bought it for a tester to confirm my suspicions. I tested this device with a known good battery and found it to be accurate enough. I found that my phone's battery is dead and can be replaced. This device really saved me. I took my phone to a repair shop to have the battery replaced and found that the advertised 2800mah battery only holds 1800mah. I showed them the test results and they replacedโ€ฆ

Pros
  • Pleasant to use
Cons
  • Null

Good clear bright display with accurate useful information.

USB tester works very well, arrived on time and as described. There are some similar testers at Revain, some of them are more expensive and have the same features as this one, making it very good value for money. I specifically went for the option without the built in cable as I had concerns about the durability of the built in cable which would be difficult or impossible to replace. The display is nice, sharp and bright when in use. With the key button you can switch between different screensโ€ฆ

Pros
  • Great product
Cons
  • Only available in black

Convenient to turn on - voltage tester

I've been using this very consistently for a while and it's useful. It has a lot more power than abuse, but its main purpose for me was to detect and prevent dirty electrical spikes. First I wanted to test 5.01v. - 5.14V devices, but I find that they are most commonly used as a 110V direct wall outlet with 500J surge protection. USB outlets do not have 500J surge protection, so this device serves as a vigilant electrical company for quality control. The voltage is typically 5.06V, but the 110Vโ€ฆ

Weak LCD and small characters make it difficult to read.

I bought a Musou USB gauge along with a Drok-300043 gauge to compare them. Gorse was delivered first so I had 2 days to play with it before Musou arrived. When the Musou arrived, I pocketed it and found I couldn't read the display unless I got very close to it. The LCD was too dark and the characters were too small. I immediately repackaged it and sent it back to Revain. I had to take a photo of the display before sending it back to include in this review. However, you can see that the photosโ€ฆ
