Can you test one of the Anker chargers? I've been quite pleased with the 5 port, 40 watt model
I have ordered all 3 chargers, depending on what sequence I publish in, it can be a couple of months before the review is published.
Thank you for the list - I like it just the way it is.
We are currently debating this topic on mysensors.org (see thread ) and someone posted a link to your excellent reviews. We were wondering if the meanwell GS05E-USB or GS05U-USB are safe as it is almost the only one to have OTP. Meanwell is generally a good company and the price is very reasonable.
As we lack the equipment and expertise to test it, we would be grateful if you can give it a go. It is available from :
Mean Well GS05E-USB

I do have a thread to put review wishes/request in. There is two problems with the above:
1) I have a queue that is a couple of months long.
2) Shipping is £20 from mouser EU.
I would expect meanwell to make good products.
http://www.tme.eu/en/details/gs05e-usb/mains-power-supplies/mean-well/ - much more reasonable - 8 EURO shipping and 7.20$ for the product. It seems like it is a new product and will be available through many more shops as new shops get it every day.
I understand the queue… But as this charger is unique (at least in what I looked at) and priced well below other chargers of this caliber it might be in the benefit of the community to maybe give it priority. If not, we will wait patiently…
I really can’t see what’s so special about this charger…
Meanwell is a good company but on lower-end products they tend to use dodgy CapXon capacitors. For example APC-16-350 uses Samxon/CapXon capacitors for input/output filtering and i really hate those CapXon’s (KF series) as they go bad even in highly undemanding applications. What’s more irritating, psu is potted making capacitor change very difficult if not impossible…
The difference between this charger and any other charger we looked at is that it lists Shortcircuit/Overload/Overvoltage/Overtemperature protection. No other charger I looked at has all 4. I only had good experience with meanwell - I am no expert but all their stuff looked well made, not like a 5yo did the soldering and no components that looks like they were recycled. However, I used different lines and as always, YMMV.
At mysensors, we need reliable powersource that will be reasonably safe to keep inside a box or inside the wall cavity. Because of that we need a charger that has OTP. Many members use the square Chinese chargers that failed almost every test. We are looking for something that:
- Can be bought from the source or undisputed distributors
- Normally priced - each of us uses over 10 chargers only for the sensors. a 20$ sensor will make the charger cost more than the sensors….
- Has as many protections as possible - as I said it needs to be in a box or behind the switch
- reasonably clean signal - the arduinos/nrf are not very fond of noisy signal.
If you can recommend any other charger that fulfill even almost all these requirements, I’ll be very happy to use it.
When i said nothing special that excluded typical low cost china PSU.
All that protection is based on controller IC capability. Most of controllers are internally protected for these conditions, so nothing special about that. But beware that meanwell states OVP 105-200% rated output voltage.
I have ordered on now, but I do not know when I will review it.
That might be so. Can you please point me to any wall-wart (meaning that it connects directly to the wall) charger that state having OTP? I failed to find any.
Thanks, this is much appreciated!
Hi HKJ. Seems more and more surge suppressor power strips on the market are featuring built-in USB charging ports. Have you considered disassembling and reviewing some of these? I’m curious how they compare to dedicated charger units.
Only one and it is not a surge suppressor, where I have received some requests:
I expect to publish the review later today.
If you want me to review some other, please post some links to where I can get them (Remember: I live in Europe).
It looks like BlitzWolf_40W_5_port_usb_charger and Eachine_PA40W_5_channel_usb_power_charger share the same board. But Eachine is using a much better quality 2014 rev., and BlitzWolf_40W_5_port_usb_charger a 2013 rev.
I am not sure there is much quality difference between the boards.
Many 5 port usb chargers uses revisions of this board, some of them better than other (Anker has electronic overload protection, not a fuse).
My favorites, in a image. Sorry.
I am unable to format the text correctly in the forum.
NOTE:
- Anker devices have electronic overload protection (best), not a fuse (worse) as others.(HKJ)
- Eachine only supports Apple 2.1A
HKJ, thank you for the reviews.
Hi HJK,
Thanks for all the USB mains adapter testing and the details how the 2.5 and 5kV test are done using the Uni-T 513: test time usually less then 30 seconds and your quote:
Regarding the category of smaller green ticks (possibly safe, haven’t read the CE test report): Have you ever tried a distributor/manufacturer to ask for their CE test report?
Sometimes
My guess is because those do not use synchronous rectification but rely on the cheaper diode bridge?
