Q: Is there a marking of the laser class on the flashlight? I'm asking because of the import regulations.

gefragt von BG492245182 auf 2021-07-15 10:39:42

farkasditke73 Strictly speaking the emitted light is not laser so there's no need for a laser marking. An internal laser source is used to excite the phosphor: LEP, Laser Excited Phosphor. If it were laser the light wouldn't be white.

Q: What is the firmware version of this product? It's important to know because devices with earlier firmware versions cannot be updated. I don't want to end up with such a device.

I'm not a gamer so I don't need a mouse with many buttons. This basic mouse is exactly what I need: smaller than average in size (my hands are smaller than average, too) and a flat design so it doesn't strain my wrist. My laptop has only two USB-A sockets so the mouse's Bluetooth capability comes in very handy. Additionally I can use it with my tablet and phone, too. A lot of much higher priced mice have no Bluetooth capability. It's a shame that the RGB light can't be turned off. It goes out in about 40 seconds but lights up again whenever you move the mouse. Maybe I'll solder out the RGB LED. The built-in battery is a removable unbranded button-top 14500 with a capacity of 250mAh as measured by my LiitoKala Lii-M4S. It takes less than an hour to fully charge a depleted battery. Unfortunately the mouse doesn't seem to have overdischarge protection, it's still working at 2.8V (my LiitoKala Lii-M4S stops discharging at this voltage), or it kicks in at an even lower voltage, which is not so good for the battery. All in all, this is an excellent mouse for general use, especially for people with smaller hands. Highly recommended.

farkasditke73 For those interested: it has a microUSB slot for recharging and a short cable is provided so you can recharge it from your PC or laptop.

This is a good and versatile charger. Below I'll give some additional info you won't find in the user manual. 1) Short touch any key to turn on the backlight. It will stay on for 30 seconds, then it will automatically turn off. 2) Long touch the Current key until the beep tone stops. This will turn on the backlight permanently. Repeat this two times to turn the backlight off. 3) The charging process of Li-ion batteries will will be terminated at 4.22V but the display shows 4.20V. This is +0.48%, barely within the usual tolerance of +/-0.5% given for other chargers. I wish it were closer to 4.20V. Other pieces of this type may vary. 4) In Discharge and Test modes Li-ion batteries will be discharged to 2.82V. This is no problem with the charger, this is the usual way to test capacity but not so good for the battery. So don't use these features too often! My personal opinion is that the max. discharge current of 500mA is too small, it takes 15+ hours to test a 5000mAh battery. This is way too long, I miss an option for 1000mA discharge current. On the other hand you don't test batteries even on a weekly basis, so you can let the charger take its time. 5) Disconnect the USB input cable to enter USB power bank mode. The device draws 150mA from the battery in standby mode, including the backlight, which is always on in this mode. With a load of ca. 1300mA it draws 2A from a full battery. At first glance it may seem bad efficiency but it is not because the 4V battery drives a boost converter to produce the 1300mA at 5V. This requires ca. 1625mA from the battery, plus the 150mA standby current. So the efficiency of the boost converter is 1625/(2000-150) = 87%. This is very good. All in all, this is an excellent product, very good value for your money. Highly recommended!

Q: is it possible to get such a heater which runs in 12v instead of 220

gefragt von Donald auf 2023-12-18 11:01:15

farkasditke73 Impossible. It would require two hundred and fifty amperes on twelve volts. The resistance of the heating element should be forty-eight milliohms.

The seller Dear, thank you for your support, its PWM control, our switching frequency is very high, when the brightness is low, you should not be able to see the flicker.

A simple but reliable charger that does everything a charger should do. Overcharge protection works well, the charging process is terminated at 4.18V. 20mV below the nominal 4.20V is much better than 20mV above. The capacity loss is negligible BUT it lengthens the life of the battery. If you charge only 1 battery and you're not in a hurry, you are advised to use the slot on the left. This slot charges the battery with 1A, while the other uses 2A. A lower charging current is good for the battery. If you charge two batteries, both are charged with 1A.

Q: Hello I have bought this multimeter but when I try to test AC frequency the display shows me 50hz without connect the probes to AC voltage what's wrong with it?

gefragt von ZaidHweimel auf 2018-11-20 08:46:56

farkasditke73 Willsgood gave the perfect answer. I may add the following: The AC voltage generated by the stray electric fields has a very high impedance, and so has the voltage (or frequency, for that matter) input of a DMM. As soon as you connect the lest leads to a voltage source, its lower impedance practically shunts the voltage generated by the electric fields so they won't affect your measurement.

The USB socket of my TV set is on its back, very inconvenient to reach, so I needed an extension cable. This. is a simple but useful cable, I'm satisfied with it. Now I have to plug in the cable once and for all, and I can easily plug in or unplug the pendrive containing my movies.
