Q: Does anybody know how to activate the alarm siren? All other functions are working
gevraagd door Volker op 2020-09-03 06:32:55
Volker Hi user, It can measure the so called ESR (=Equivalent Serial Resiatance). Your assumption is much too high. A quality battery i.e. Li-ion should show an ESR below 80 mOhms.

gevraagd door BG161515441 op 2021-09-06 09:53:54
Volker Sorry, I don't know. But I suppose that this cable fits to any transceiver of the UV series, since I cannot imagine that BAOFENG has different cables for their devices.

gevraagd door Avishek op 2021-08-27 10:27:35
Volker It can be used during charging
2021-08-28 04:00:13 Nuttig (0)Q: can it work with 220v .if yes how
gevraagd door BG234817391 op 2021-08-07 02:16:06
Volker No, this is impossible. You need either a super capacitor (very expensive!), or a lead-acid battery which is capable to deliver 500A at 12V. A capacity of 20Ah is sufficient, since only a short impulse is required.

gevraagd door BG129532405 op 2021-04-28 03:01:22
Volker Sorry, but I can not tell you since I don't know your location. US is 110V AC, Europe 230V AC. Decide yourself.

Volker This borescope works with every Android phone. You have only to download a proper App, e.g. "USB Camera", which is excellent.
2021-03-31 09:17:19 Nuttig (0)Q: Specs says "640*480, 1280*720, 1920*1080 for HD model (7mm)" I can get only out 640x480. Why?
gevraagd door Harry op 2021-03-23 12:26:10
Volker Generic resolution is like data sheet. It is not a question of the hardware but responsible is the used app. Check different ones until you have the one which pleases you

gevraagd door BG101652564 op 2021-03-06 01:14:37
Volker I don't know. But, why would you buy batteries? There are already built in 2 units of high power Lithium-Polymer batteries and the unit is ready fo use.
2021-03-06 02:56:21 Nuttig (0)Q: Its good for Samsung S 9+ fast charging on wireless?
gevraagd door ZYARTY op 2021-02-14 07:32:12
Volker Yes, it is suitable for this smartphone.

gevraagd door george op 2021-01-17 02:27:47
Volker Sorry, I cannot help since I still didn't receive the product.
2021-01-17 03:30:08 Nuttig (0)Q: it's compatible with Doogee s68 pro?
gevraagd door fglaszlo op 2021-01-01 11:22:56
Volker It is compatible with every device which has the USB wire connectivity. Wireless charging is only working if the device has the option built in for this kind of charging.
2021-01-01 12:28:45 Nuttig (0)
Volker It is not the third row, but the first row from the top. It is not easy to read, since the characters are tiny (height only 1mm).
2020-12-22 03:17:20 Nuttig (0)Q: Is it ok to use this product with a 12v 20ah gel car battery?
gevraagd door BG453245444 op 2020-12-14 09:50:13
Volker It is ok, but please check whether the circuit is working. The unit, which I received is faulty. It never could work since there is a severe fault of the circuit design. I had to correct this with major effort.
2020-12-14 10:07:19 Nuttig (1)
Volker Simply remove the back cover and connect the two points "Reset" and "Gnd" with a piece of wire or with a paperclip. This causes a RESET.
2020-11-23 10:27:59 Nuttig (1)Q: How can you choose between two amount of foam? I threw out the manual, sorry...
gevraagd door swiftplus op 2020-11-16 04:52:25
Volker Well done! Manuals are always scrap. I achieve very tough foam with a ratio of 5 volume parts water to 1 volume part soap. With that mixture the pump gets the needed volume of oxygen which is reponsible for the foam density.
2020-11-16 05:16:40 Nuttig (2)Q: why does mine start fading after 10 seconds? I have had it for 3 days?
gevraagd door BG174534132 op 2020-11-04 02:05:05
Volker Either you have a weak battery and if not I suppose that the LED is overheating and therefore is fading. Please check whether this effect is unique or reproducible.

Volker Electrically nothing can harm the operator, since 4.2V cannot drive a dangerous current through operator's body. The only accident which could happen is damaging the device by short circuiting and injure the operator by fire. Therefore no extra insulation is necessary, but it is recommended to wear protection gloves.
