XINTEST HT-501 CO2 Meter
Portable CO2 meter and data logger with battery and good CO2 sensor inside.
The only really wrong thing about this device is it always show temperature higher than it is for about 2°C (for example 28.0°C instead of 26.0°C) and it is not something related to wrong sensor placement.
Pros
- Portable
- 20h work from a battery
- LCD Color zoning
- Datalogger
- Setup time and alarms from PC
- Sensair S8 CO2 sensor
Cons
- Incorrect temperature measurements
- No time and date on the screen
- 30 sec warmup time

uHoo
uHoo – most advanced air quality monitor, at least if consider a number of sensors. Including advanced sensor like CO, CO2, PM2.5, VOC, O3, NO2. And also traditional like temperature, humidity, and air pressure. Measurements look accurate enough.
The device does not have any local indicators. Not a single color LED to show air quality status. The only way it communicates with the world is Wi-Fi and mobile application. The application (v 3.8) or backend infrastructure that makes it work is unfortunately unstable. Also, an interface is poorly adapted to iPhone X.
uHoo is not portable due to many reasons like no local indication, no battery, need Wi-Fi (and new connection setup will take time).
Long time no Samsung. 🙂 Mostly because of the previous experience (read in Russian). But anyway did a test of Adaptive Fast Charging (AFC) from Samsung. Using Samsung S8 with AFC charger from the box.
What can I say?
I see some cheating with charging percentage displayed by the phone to get “Full Charge in 90 minutes” in reviews.
But the real numbers are more like 120 minutes.
Just to compare with a device that shows true percentage see image below
| 50% | 80% | Show 100% | Real 100% | |
| Apple iPhone 8 5v 12W charger | 00:28:00 | 00:51:00 | 01:41:00 | 01:41:00 |
| Samsung Galaxy S8 AFC | 00:44:00 | 01:08:00 | 01:28:00 | 01:56:00 |

Green Day CO2 Monitor
One of the oldest devices I got for CO2 monitoring is AZ-7788 GreenDay. It is 4 years old now. The device is still good and accurate.
Used as portable mostly because it has an LCD and not require setup.

NextBase 612GW
First 4K/GPS/WiFi Dashcam on market.
Metal body looks good. The device is relatively heavy. Weights distribution and center of mass are not perfect and it sometimes affects image quality (right side vibration). Compatibility with 412GW GPS connector (make upgrade easy and fast). A touchscreen is much better than sensor buttons on 412GW. A physical power button is also good. What is absolutely wrong about this dashcam is Wi-Fi speed. View of any HD video impossible. Copy 1 minute of 4K video (340MB) is taking so much time (more than 10 minutes) that my 3 attempts to do that failed for different reasons. Wi-Fi is only usable for a preview of Low-Resolution files (if enabled). Power consumption is high, but accumulator capacity and charging speed is not.
Update 2018-11-26, after 10 months of use: Too much hangs. Need to push Reset button at least once a week. Dashcam does not allow to go into the menu without the need to first stop recording.
Pros
- 4K or 1440/60p
- daylight video quality
- touchscreen
- GPS
- removable CPL filter
- timelapse and parking mode
- speedometer screensaver
Cons
- expensive
- charging is slow (2h, 5v 0.15A)
- Wi-Fi is slow
- video quality at night
- “NextBase” logo on footage
Technical details:
- Accumulator 3.7v 280 mAh 1.04Wh
- SoC (CPU): Ambarella A12S75
- RAM: 512 MB DDR3L 1866
- ROM: 256 MB NAND Flash
- Sensor: SONY EXMOR R CMOS
Yet another USB Tester with PC/MAC connectivity. This time using Bluetooth.
Device
PC Software
Application is old-shool and simple. It cannot resize to use full screen, cannot autodetect port to use, cannot show large graphs.

Yet another USB Meter. AVHzY CT-2 (ChargerLAB POWER-Z KT001, Kotomi Premium). It can both store curves offline or be used together with PC application.

not as good as ChargerLAB Power-Z KM001 has. Poor visualization and export options. But at least it has English language interface. Support site available at http://www.avhzy.com/
