I just got my nc301 today. It didn't seem all that loud to me. Not that it was whisper quiet. Btw, I think you left the protective plastic over your readout... probably why you were having trouble seeing it. Anyway, I topped off a battery today and it seemed to work great. I don't plan to use it that often so hopefully it will last me several years.
I wrote a short comment and then I looked at my purchase history. I bought a charger that looks identical but with a different name. I’d image this is similar to Anytone/Retevis/Radioddity radios that are rebranded at the factory. The fan is loud … charges well … reasonable priced. Works on my kids’ 12V ride-on toys, too!
I bought this charger on aliexpress for about half the price vs Amazon. It's really a 15a charger as others mentioned. I've used it for about 1.5 years as charger from my alternator. It turn on and off several times a day so pretty good for the price. I have however replaced the fan and it's much quieter now.
Great review of that charger. Sounds like a big 200MM fan in it. but it is small. Some cooling fans are like that. it is the blaid design that makes the noise. anyways it keep the parts inside cool . Love the fact is has 24V and selectable for outher battery types. This is great for tractors cars trucks and much more. Most of them have a noisy fan. I have a charger brought to me it was 20 amp LiFePO4 12.8V only and a different brand. the problem is when plugging in at camp cite you can't listen to AM radio . In fact neighbors complained at campground. I did some tests and RFI was super bad. I ended up putting 2 toroids on it. FT 240-31 cores. 1 on the DC side close to charger. that dropped the RFI somewhat. I tried 2 cores and no more improvement so I put ferrite on AC cord but charger and BINGO . dropped more that half the RFI noise. Their was still some noise I could not get rid of. With out ferrite and in the RV the RFI even got into the radio speakers in the RV with the system off. made a very quit buzzing noise in the speakers. The ferrite fixed all that. now only some weak AM stations are affected. So as far as RFI testing use a AM radio as well as ham radio. Love that battery build. I do not buy a inverter unless true sine wave. I test on a scope and under load . Over time a non sign wave inverter can damage electronics like caps going bad over time. It is the current spikes from a square wave of stepp wave that causes the failure of filter caps. 73
I have one Chuck although a different brand. Its 20A but it quickly goes down to 15A and stays stable at that. RF Noisy on HF but never use it when on the radio.
Thst fan voice is not as loud as u show it on the video, thst fan is barely noticeable in real life , ur microcontroller makes it much louder thsn it is.

Yes I have seen another branded charger that looks the same. Thanks for the comment!

Oh wow that's crazy, thanks for sharing it's in the memory bank lol.
aka HTRC P20 in the UK, as you say, it works well, but as somebody mentioned RF noisy particularly on 6m I found.

Yea same here i'm usually not charging when on the radio.
Thanks for sharing. Would have liked to have seen if it's noisy on the ham bands. Thanks
Steve, k7ofg.
Stephan, a few have reported in the comments that it is noisy on some bands.
