Hi. Newbie here—I just signed up. I’ve been a fan of HKJ’s website since finding out about it two years ago and it is because of his reviews that I purchased a couple of SKYRC MC3000 and an Xtar Dragon VP4 Plus chargers. I sent an email to his website asking for advice and he was nice enough to reply and give me a recommendation. Recently, I got into USB meters and purchased a Power-Z KM001C also because of his review of it. I also purchased a Power-Z FL001Super and a KT001 and I’m thinking of getting a MF001 or a WITRN X-MFI w/ bluetooth. Which do you guys think I should get?
I’m also surprised to find RD tech active here. My first ever USB meter was an entry level RD tech brand but back then I only used it to check if I had a fast charger or not. Now, I use USB meters to check for noise in chargers because I want to protect my devices. Is there an RD tech product with ‘oscilloscope’ feature that can graph and record electrical noise?
The UD18 tester looks interesting… I’ve always wanted a quick way to check DC5.5 power consumption. Maybe this tester will help. I wonder what’s the upper current test limit for DC5.5 on this tester? I don’t seem to see the specs from the product page. Although the sample pictures on the product page show it testing laptop charging at 20v 3A for 60-watts power consumption, and another picture showing 30v @ 3 Amps for 90 watts (connected to a load tester device)
I’m looking for a good USB Power supply / charger that supports QC 4.0 / PD 3.0 / 45w to 60w.
I.e. Baseus Speed Series 45w / 60w model
Or you test a similar PS that can be bought on BG / GB / FT or AE? Thank you!
@HKJ : base on your test result, I almost purchased 8 USB chargers for my family, friend and myself, I love the way you did but I also gave you a comment about the difficult in searching your device tested. Would you mind to add the search functionality to let people can search by device name / brand name (full or a part), model…etc ? it will be more convenience for all of us.
THanks
Hello! Recently found an intriguing DIY device in AliExpress, it is an adjustable CC/CV DC/DC boost converter with very low input voltage (2 - 24V), high input current, input overcurrent protection via fuse and resistor adjustable input undervoltage protection. It even features USB output (!) and to top it off its :-)) cheap:
I’m not a very big fan of those trimpots on DC converters. They might not work for very long. Some are rated for only 200 cycles, which comes up fast if you’re constantly adjusting the output.
Thanks for video pinpointing the difference maukka. I was already aware of, trimpots are easily replaceable with potentiometers. Now that I'm here let me suggest using logarithmic potentiometers for led brightness adjustments, as is the case with audio volume controls it'll result in a vastly improved accuracy.
Yeah, I did, but compare with the search functionality to limited the condition/filter the guest want to see, the search functionality of web browser will not be the good one
I tried to find Enpower USB 1 port 2A as your test but seem it was too old device so that could not find in the market, just can order enerpower-ep-10b-5v-2a-usb-black-10w now. Thank you
I've been looking for a DIY power bank case with some extra functionality and found an interesting device for the DIY crowd a while ago, an inexpensive power bank/mobile power supply box from (?) AILI, takes six cells in 3S2P arrangement:
I tried to contact with local DHL service to send it to EU area (you mentioned you are in Denmark) BUT the delivery cost is more than 12 times of the charger price, sorry, your living area is quite expensive so send smth like this charger
Just dropped by to say that I've found something interesting. It's an USB powered soldering iron, looks close to the one which once reviewer Dave from EEVblog tested:
But it evolved…
… into this new super cheap Aneng LT002 soldering iron!
