Q: Do you recommend screen protector/tempered glass? What should be the right size for this watch ( e.g. ~46mm covering full screen, 1.28 inches ~ 32 mm covering LCD part only etc)?

oldmainer No need for protection. Glass is great

Q: Hello, after some usage the light start to behave strange. It started to activate by its own and now the controller is gone. When I plugged it out for a long time it sometimes work but mostly seems dead. Check the cabling and it seems the controller is powered. As far as I see there is a one 5V output and 2 negative outputs. If I manually shorted out the negatives I can get the lamp work with different colors ( possibly if I short out both to ground I may have the third color ). So, is there a schematic for the controller that seller or any one can supply? If not, a guide for building the controller will be helpful. It seems I figured the lamp color choice, but how to adjust the power ( dim the light )? Should a simple pot do the job? My Best regards.

Pioppo2 anche il mio regolatore funzionava male e quindi lo sostituito con un semplice commutatore a slitta per poter scegliere il colore della luce, la regolazione non serve perché la potenza è poca e quindi è inutile abbassare la luminosità.

I think it is the excellent price per performance AWG that you can buy. Loaded with extra features and input/output capabilities.It is pretty small so does not consume so much place in a house-lab. For the durability, time will tell. I do not know if it is a feature of a new FW or not, but the channels being on as soon as the device is powered up ( that some people complained about ) can now be controlled ( you may select the default action for both channels individually ). That means the manufacturer keeps the track of the complaints (at least some) and try to bring a solution on the table.

Very small, handy and practical. Amperes display is simple but very helpful. Strange that the unit does not contain a plug (EU, US etc), I think they leave the cable open to let you use any type of plug with it. Not a big deal since the price is almost unbeatable.

Q: Please can this adjustable power supply be used for a 19.5V, 3.9A laptop?

Asked by ezryda on 2020-03-10 06:17:16

H_U_L_U The power you need is roughly 76W, however this power supply is 72W. Even though they are very close, I do not recommend to use this unit for long term. You'll better use a power supply with 19.5V option ( possibly adjustable ) but have an output greater then 76W ( or 3.9A @ 19.5V ).

Small sized, fast and simple interface. Gigabit ethernet is a plus if you are streaming 4K content on your local net. The display on the front is a bit dull/faint and only shows time (not the net/play etc. logos). Not important, since it is too small to be seen if you use it several meters away from you. The remote came with it is very simple and hard to operate ( you need to direct it to the device ), unless mine has a problem. But this is not a dealbreaker for me, since I use all in one remote and keyboards for it and the price is considerably low then its rivals.

Very well built, easy to use and compact buck PS. The only regret that I did not bought the wi-fi version since by the time I ordered the explanation mentions only android software. As far as I see, the wi-fi module is just an add-on card so I believe the both versions have the same firmware. Thus, why not sell the wi-fi module separately also? I believe most of the people, like me, regretting not getting the wi-fi version would buy the wi-fi module. Or, if the vendor does not want to manufacture/supply only wi-fi add-ons, they may guide us for compatible wi-fi modules ( as far as I see, what they use is a standard serial-to-wireless module ).

Small and portable, not very noisy. The airflow is a bit low (but it is OK for warm air) and warm ( do not expect it to act as a heater ). It only provides mildly warm air.

Tiny and handy and the battery is adequate. It is not one of the fancy blade-less units (blades are inside the body directing the airflow) and it can't be at this price range. Unfortunately it is a little bit loud (I do not know if I got a poor oiled one :) ), but it does its job.

Very handy and sound quality is just OK as expected. There is neither English manual nor a link to download one, so discovering all the functions/setups may be a little bit frustrating. But well worth the money.

Well built and functional for using with everyday household devices. Adjustment knob is a bit out of scale ( only a small portion is used to adjust the voltage ) and hard to fine adjust, but as it is not a lab unit it may be tolerated.

Well built and comfortable to use. Wished to withstand 250 or 300 Amps ( and probably will for short periods ) but 200 Amps is enough for most cases.
