Hi there!

We are planing to develop a new USB charger with more functions than Allmaybe CU6 and we sincerely hope it can be customer-orienated and truly help people to make charging affairs easy and safe. This question is the one on which we want to hear your opinion most.
Your participation will be highly appreciated.
Thanks.

I don’t think quantity matters as much as total power. What really matters is how many devices that I can give at least 1 amp to. I see no point in having tons of devices plugged into one charger if they aren’t going to get more than a trickle.

4 is what I picked

If you can give it USB IN and let it operate as a powered USB hub as well that can be useful

I voted 6, and 1 or 2 should be USB type C. The C port/ports should do 3 amps. I won’t buy any new chargers without type C.

Good point. Thanks.
I care the quantity simply because our 60W 6 port seems to fulfill all the expections you mentioned but best sellers always fall on the 2-port (of other brands like Anker, iClever). One of our customers told us he only used our 6 port when travel with family and he prefered 2 to 3 port.
I have communicated with other customers and received so many different answers. So I started this poll, hoping to gather more data to better analyze.
Thanks again.

That’s really a bold proposal. Thumbs Up But till now, I have seen no typical product of any famous brands having both two functions, and more important, both functions can be performed equally and perfectly.
I guess it will be a big boy if it’s possible, right?
I will communicate this idea to our engineers and see whether we can make it. Thank you for your advice.

You speak out the same puzzle I have. I always wonder what people will do with those 12 ports. But search “12 port USB charger” there will ba aboudant sellers and they do have sales, even Anker has a Powerport 10 with 10 ports. Big Smile
In fact, we will not consier more than 6 ports at present, but since it’s a poll, I guess it’s better to take more people’s special needs into consideration.

I think it is great you ask and address peoples input here!
When you are done building it, be sure to send one to BLF user HKJ for in depth analysis!

Thank you. Beer
We really appreciate HKJ’s hardwork on reviewing products with so excellent insights. His review for our CU6 is really professional and helpful. He is absolutely the first reviewer from whom I would like to see our product review. Big Smile

Four ports usually is enough for daily use but not more than six . Please allow spacing of one USB port space between each of the four ports for easier plugging in and removal of USB plug. ( most of the multi ports charger are of the standard spacing type )

Also, a switch on the back, a small one, like the Tronsmart Titan has. When not in use, you don’t have to unplug it, just switch it off.
And oh, 6 ports is enough, with at least 2 QC3.0 ports.

In new charger please pay attention to EMI/RFI switching power supply generate. Use proper filtering on primary and secondary circuit etc.
I’m ham radio operator and 90% of chargers or switching power supply’s are pain in the ass, because it generate huge amount of radio interference can be heard in ham/CB even FM radio in car or home.

Besides I would like to have on/off switch, 4 USB ports with at least 1 QC port.

+1. Great Idea. Even though the Allmaybe CU6 uses very little power when it is connected to the mains, but isn’t charging any device, it would be nice to have a switch on the back to be absolutely safe.

I also agree that 6 ports is enough.

Edit>> I can’t vote 6 ports *and *at least 1 QC3.0?

Clean power output Thumbs Up And maybe a compact 3-4 port wall plug version instead of the long power cable ones we have now.

Everyone’s use case is different, and we all think ours is the ‘right’ one. Cool

I have a couple 5 port BlitzWolf chargers, one with a quick charge port and one without. I think if you are making a new charger, QC ports (at least a couple) are mandatory. Having extra space so a USB meter can be used on any given, or even adjacent ports is a very good idea. I would prefer that the power supply have a standard power cord rather than a wall wart brick so I can plug it in and keep it on my desk without finding space for another transformer. If you do use an external power supply, please use 12VDC in, with a center positive, ‘standard’ connector. By doing so, it could fairly easily be used in a car, boat or anywhere a 12V deep cycle battery might show up.

USB C capable seems like it is where the industry is going, I don’t have anything that needs it yet, but if it is backward compatible with USB 2 & 3, go for it.

Having the charger be functional as a high speed USB hub would be absolutely marvelous, and I would buy one immediately right after HKJ approves it, and probably 3 or 4 more soon thereafter. I work with several High School competitive robotics teams (FIRST) and being able to (quick) charge multiple devices between matches while still using them to program changes and debug would be very helpful.

An onboard power switch with LED indicator would also be nice.

To Minimoke: Thanks for your advice, quite practical.

To Maukka: May I further ask, if there is a LCD screen on the charger itself displaying charging current, voltage and things like that, will you still prefer using power meters when charging?

Hi dodge_911, your idea will make the charger more convenient. That’s good. Many many thanks.

Thank you! There is no doubt you made a wonderful conclusion of all we had talked about Thumbs Up and 12v DC is new.
Our present CU6 has a LED indicator, but it makes no big sense in fact, I guess.

Everything should be at least 2A. By that I mean 2A for each USB port and 2A for each battery. For the VC4 that means 20A in total.
The 6 ports on the VC4 fit perfectly so anything less than 6 ports would be bad.

Some additional wishes (for another product)
- A power bank function would be great.
- A flashlight function (if a power bank). Nothing fancy. Just an emergency light.

I fully agree with the suggestions made by “Lazy-R-us” but have one extra suggestion

Quote:

I think the polarity shouldn’t matter. It’s quite easy to ‘correct’ the polarity.
I have a Braun battery powered razor. I just put it in the charging cradle. It accepts everything from 6 DC to 240 AC. Flexibility is great.

Chargers: 1xBasen BD01 5/5, 1x Gyrfalcon All-88 4/5, LiitoKala: 3x100 3/5, 2x202 3/5, 1x402 3/5., MiBoxer C4-12 3/5.
Flashlights: DQG Tiny III 26650 5/5, FiTorch MR35 3/5, Haikelite SC26 HD 3/5, Lumintop Tool AA/AAA 4/5, Nitecore LA10, Sofirn C01 BLF 3200k/5600k 2/5, Zebralight H600Fc 3/5.
Powerbanks: EasyAcc 26800 mAh 3/5, Xtar PB2 4/5, Xtar PB2S 5/5
Waiting for: (DQG Tiny) 21700 EDCs.

I think it shouldn’t be complicated at all.
The question shouldn’t be “How many ports?” but “How many batteries?”
The number of batteries defines the size of the charger. Then simply add as many USB ports as possible.

I think best sellers fall on 2-ports because they are cheaper and/or smaller. Nobody hates more ports.
Maybe you should take a 2 model and start thinking how you could add an extra port without increasing the size of the device.

It’s about size AND functionality.
I’ll explain that from my own personal situation
I fly from Europe to the USA 2 times a year.
I take with me:
- A phone, a tablet and a bluetooth device for audio.
- A 13500 mAh powerbank.
- A charger which I use when waiting at the airport.
- A few batteries for my flashlight and a charger.

With limited time at the airport it’s very important the charging goes as fast as possible.
When your charger also has a power bank function I no longer need a powerbank + flashlight batteries + charger. Only your charger.
So while your product may be a little bigger than other products it’s 2-in-1. For me it would save space and weight.

One function I’ve never found in any powerbank is the ability to charge low power devices. I have hearing aids and a small bluetooth device that streams audio from my phone and tablet to my hearing aids. It small so has a small battery with which only takes a few mA to charge. Powerbanks just switch off at such small loads. They assume my device is a large battery on ‘trickle load’.
So allowing tiny loads would be great. But not only for people who are cursed with bad hearing. I have a small USB to HDMI device so I can play movies stored on my tablet on a TV (in an hotel room). That device needs external power. And guess what. It draws so little power my powerbank switches off.
To summarize a charging option for very low power devices (uses a regular USB cable)

Chargers: 1xBasen BD01 5/5, 1x Gyrfalcon All-88 4/5, LiitoKala: 3x100 3/5, 2x202 3/5, 1x402 3/5., MiBoxer C4-12 3/5.
Flashlights: DQG Tiny III 26650 5/5, FiTorch MR35 3/5, Haikelite SC26 HD 3/5, Lumintop Tool AA/AAA 4/5, Nitecore LA10, Sofirn C01 BLF 3200k/5600k 2/5, Zebralight H600Fc 3/5.
Powerbanks: EasyAcc 26800 mAh 3/5, Xtar PB2 4/5, Xtar PB2S 5/5

The reason I spec’d center positive is that so much of my other electronics gear already has center positive. So I have lots of cables made up that way, several wall wart transformers and a couple cigarette lighter (or are they now ‘vehicle power outlets’?) cables. The LiitoKalla Engineer 500 charger supplies are my most recent addition.

A supply like your Braun that is happy with whatever you feed it would be absolutely perfect.
