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.

uHoo and iPhone

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).

Samsung S8 AFC charging 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.

Charging Samsung S8

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

iPhone 8 charging

NextBase 612GW

First 4K/GPS/WiFi Dashcam on market.

NextBase 612GW

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.
