I am charging my S10+ (Snapdragon version) with Anker A2029.
S10+ supports Samsung AFC, USB-PD and QC, while Anker A2029 supports USB-PD.
I am measuring the voltage with a USB type-C meter made by Satechi.
Plugged in the cable, around 4.8V is measured. So it is not fast-charging with USB-PD 9V.
I have borrowed the Apple USB-PD charger, and it can charge with 9V.
I have unplugged the Anker A2029 from the "plug-extension-bar" (what is it called in English?), and pluged onto another one on another location.
And now, Anker A2029 charges with 9V.
So it seems to be too many electric applicants consuming power on the bar, making A2029 lacks of power.
Plugging back A2029 onto the original extension-bar, tring to charge the MagicPro ProMini PM15, it charges at 19V.
I am confused.
Why can't the A2029 charge S10+ at 9V?

I'm aware to take advantage of "DASH" charging (5V 4A), you need a DASH charger with the circuitry, and a DASH capable phone.
1. Can I theoretically use any USB C to USB A cable with my OP5 and DASH charger, or will the phone limit the current? I understand cables may not support 4A of current, but I want to know will the charger and/or phone stop it from pulling so much current? What if I buy a high-quality cable off Monoprice? Or does the cable have to be "DASH Certified"?
2. If I were to plug in another phone into the DASH Charger and official cable, like say a Nexus 5X, how will the Nexus charge? The Nexus usually pulls 3A from a 5V charger. Can the Nexus still pull 3A from the DASH charger, or will it be limited to 1 or 2A?
3. If I were to plug the OP5 into another, non-DASH charger, what's the maximum voltage/amps it can pull? For example, the Nexus 5X charger is rated at 5V 3A. Would the OP5 be able to pull the 3A, or does it need some special circuitry? If so, what would it draw? 2A or less?
Last question: From what I understand if I use a laptop USB C charger, things should work okay- especially if the power brick shows it suppors 5V, 9V, and 12V. I assume the device will tell it to use the 5V line and draw whatever current it can. But what if I have a USB C charger that only says 12V on it? Or say 19V? Am I taking a gamble then? Let's assume this charger that is only rated at a high voltage is not a "shady" charger, and they followed the USB C spec properly. Should I be okay?
Thanks.
Any input or insight on these questions? I've read a lot about DASH charging, but looking for clarity on the above questions.
1. You can use any cable with your dash charger but your phone won't take advantage of the dash charging speeds and instead will charge at around 1.5 to 1.7 amps. So far I haven't seen a single cable no matter the brand working at dash charging speeds so the only cable I've seen working with dash charging are the official 1+ ones.
2. I don't have my Nexus 6p anymore to test this out but theoretically a 3 amp capable phone could draw the necessary amperage from the dash charger since the dash charger is capable of up to 4A. However, I'm pretty sure the phone will charge at the traditional 1 to 2 amps.
3. Amperage, as opposed to Voltage, is drawn by the devices themselves meaning a 5V 3A charger will always push 5 volts and can give up to 3 amps of power to a connected device. The amperage may be below or equal to the capacity of the charger, but never more. Modern batteries and phones have special circuitry embedded in them to protect them from over voltage or excess current and the OP5 is no different.
When connected to a charger, a phone will usually try to identify the charger it's being connected to, if if fails to recognize its capacity, the phone will reduce the amount of current to a safe amount that's below the charger's capacity. Seeing as there are many different chargers, like 2A, 2.4, 3A, 4A, phones usually fall back to a safe charging current that's within the lowest capacity of the most common chargers so even with a 3 amp charger, the OP5 will probably charge at between 1 and 2 amps even if the charger has a 3 amp capacity.
4. Computer USB ports are fine since they have a 5 Volt power bus and any extra current needed is passed through the BMC configuration line and/or the VBUS line only when requested by the connected device. As for using a higher voltage, since voltage is pushed to the device, is not a good idea to use a charger rated with a higher voltage that of the device being charged because you run the risk of overloading the circuits. Phone chargers used in cars usually operate at 12 Volts but they have DC/DC converters and resistors to reduce the voltage to the 5 volts required for phones and tablets. I'm not aware of AC chargers being able to operate with different voltage regulators.
1, No，you can only use official cables, but, I'v tested that oppo vooc cable+micro2typec adapter, can Also dash charge at 5v 4a,Turst me ,the charge chip is in USB C
In case nobody else does, I'll answer question 2 on Friday, when I get to the office. I'll be able to try it with several USB-C capable devices.
Hope I won't forget the dash charger home.
So, as promised...
Today I tried the following devices:
- Nexus 6P, LG 5, OnePlus 5
- Nexus 6 original charger (model SSW-268EU), OnePlus 5 original charger
- LG G5 original cable, OnePlus 5 original cable
I used Ampere to measure the values. All three phones were at around 50% charging state. Temperature of the phones was around 30 °C (+/- 2 °C). Measurement time was around 1 minute.
The results represent the maximum stable values (shown for at least 5-10 seconds). Where there was a variation, it meant that the reading varied slowly between those two. One value means that the reading stayed fixed at that value. Amperage readings are expressed in Amperes. No approximation made and any variation of less than 0.1A was not taken into consideration. (i.e. 1.4A = 1400 ~ 1500 mA).
The tests are not scientifically rigorous and should be taken as such. These results are purely informative.
On the horizontal are the charger&cable combinations. On the vertical,the phones.
Moto & G5
N6P 1.2A
G5 1A
1+5 1.3-1.5A
Moto & 1+5
N6P 1.2A
G5 0.8-1A
1+5 1.3-1.4A
1+5 & 1+5
N6P 1.2A
G5 1A
1+5 3.3-3.4 A
1+5 & G5
N6P 1.1-1.2A
G5 1A
1+5 1.3A
If I forgot any details, don't hesitate to ask.
Thanks for the information! Your tests are exactly what I was looking for.
Dash Charger Stop charging at 83%
Is there anyone facing dash charger stop to charging at 83%? But with another charger can continue charging until 100%....
On the topic, there is a QC to VOOC adapter on TaoPao that someone tested on the OnePlus subreddit and it apparently works. I wonder how exactly it works, though. Apparently it's capable of getting 3A from a standard USB-C and QC 3.0 wall wart.
Hello friends. I got a Nexus 6p, it came with a common charger of the LG 5v 0.85A, with that charger it charges and shows slow charge, but it raises the percentage of the battery. now with any turbo charger that I test, the percentage of the battery decreases, I already tested with the turbo of my honor 8, with an aukey turbo, Motorola turbo of 5v 1.6A- 9v 1.6A- 12v 1.3A and all these do not charged my device. I would like to know if this is common in 6p. I am using RR in version 7.1.2.

The N6P does not support either quick charge, or turbo charge. This doesn't mean it won't charge at all, but will charge slowly. None of the chargers you mentioned will Rapid Charge your device. You need a 5V 3A USB-C charger to do that, and even some of these are not fully compliant with the USB-C standard. One rule of thumb is that if your charger or cable has a USB-A connection, your device will not ever charge over 2.1A, and in many cases much less. You need a USB-C to USB-C cable or charger to get Rapid Charge. Have a look in the N6P Accessories section where all the discussion on chargers and cables is taking place. There you will find a recommendations for the correct charger/cable. Same goes for a car charger. USB-C 5V 3A.

Thank you very much, my friend. I bought a motorola charger 5v 3a Type C and now it is loading quickly. I ordered by ebay a 6p nexus document. Meanwhile I'm using that same motorola.
Hey there, i'm, trying to find any power banks compatible with samsung's adaptive fast charging to use with my S9+. Are there any available? If so, are they worth it?
Thanks
I bought this directly from Samsung for $16 and it does fast charge on my S9+ but it is now out of stock: https://www.samsung.com/us/mobile/m...-10ah-with-usb-c-cable-silver-eb-p1100csegus/

Shame, that's exactly what I needed. Can't find it anywhere sadly.
Any power bank that offer either Quick Charge 2.0/3.0 or USB Power Delivery through USB Type C should work. The S9/S9+ will draw 1.67A @ 9V over QC and 3A @ 5V over USB-PD via Type C and therefore fast charge at 15W (which is its limit).
These should work, though I've not tried these myself.
Anker PowerCore Speed 20000mAh offers USB-PD but not QC, though the standard USB port offers 2A @ 5V, so while not fast charging it charges at 10W from the standard port (15W from the USB-PD port for the S9+).
Charmast 10400mAh Powr Bank offers both QC3 and USB-PD.
I have an Anker power bank (non-PD), and an Aukey wall charger so can recommend those brands in general terms from my personal experience.
Xiaomi 20,000 power bank supports fast charging as well on S9 plus.
This is available now: https://www.samsung.com/us/mobile/m...-10ah-with-usb-c-cable-silver-eb-p1100csegus/

I have the same powerbank and it works like a charm.
One note: you can charge the phone using quickcharge from the powerbank but you can also use the phone's charger to quickcharge the powerbank

Can't get Fast Charge to work with Power Banks
I've bought 2 different QC power banks:
AIDEAZ Power Bank 20000mAh Portable Charger
https://www.amazon.ca/dp/B07GJHNRK9/ref=cm_sw_em_r_mt_dp_U_8697Cb90CYK1E
iWALK Wireless Portable Charger 10000mah Power Bank
https://www.amazon.ca/dp/B07FMVRD6K/ref=cm_sw_em_r_mt_dp_U_E897CbKW2P4PD
I also own
Anker Powercore Speed 10000 QC, Qualcomm Quick Charge 3.0 Portable Charger
https://www.amazon.ca/dp/B01JIYWUBA/ref=cm_sw_em_r_mt_dp_U_Q997Cb1HQ367J
NONE of them fast charge my S9+ even though when I use the wall charger it fast charges. I even have a USB power meter to confirm that these power banks are only inputting 5V 1A.
SO FRUSTRATING!

Hey that is very weird especially since you say that your dev iui ce fast charges when it is plugged into a wall adapter. I have 2 powerbanks, one Mi Powerbank 2i 10000 mAh and the other is a Samsung Fast Wireless Charger 10000 mAh and both are capable of charging my S9+ at 15W
Hi there
I would like to buy a fast wireless charger for my Samsung S9 Plus, which is a european version and come with a wall charger from samsung, the adaptive fast charging. The wall charger from samsung has this output specs:
9.0V and 1.67A or
5.0V and 2.0 A
Meanwhile the wireless charger from Anker https://www.anker.com/products/variant/anker-powerwave-fast-wireless-charging-pad/A2501011 is sold wihout the wall charger ( to which it need to be connected of course), my question is: I can use the anker wireless fast charger with the wall charger from samsung? Because the anker website state that you need to use it with a Quickcharge 3.0 wall charger (that has more output voltage/ampere steps than the standard samsung wall power charger that I have describe above).
It was said that in order to charge at maximum power, the Note10+ needs a PD3.0 charger, with PPS support, rated at 45W, allowing to go up in current intensity to 4.5A, with a voltage of 10V, provided that you use a USB cable capable of transmitting a current of 5A.
Actually, and comparing all different kinds of chargers, I realised that the original 45W Samsung charger will charge the Note10+ at a maximum current of 30-33W, and it is exactly the same whether you use a 5A cable or a 3A cable, the current being [email protected] for both cables.
Therefore, I think that this whole 45W/5A thing is not accurate: you can use any 3A or 5A cable with the 45W charger, and you will get a good 30-33W charging power, with 20% faster charging speed than the original Samsung 25W charger.
To confirm: Has anyone tested the 45W charger with both cables?
I mean by this, using the Samsung 45W charger and a Note 10+ with 50% battery or less, first plug in with the original cable (5A) that came with the charger, write down the displayed time to charge the battery completely, then disconnect and reconnect with a standard 3A cable and note the time displayed. Compare the two times: I think they will be the same.
And if this is verified, it just means that a 5A cable is not needed for the 45W charger. A 3A cable is enough, especially as a replacement if you have lost the original cable.
