Hardware Chargeing Switch with a powerbank

Mr. Wizard · Apr 4, 2017

You are confusing ismart with QC, maybe YOU should look it up?

Qualcomm Quick Charge 3.0, is one of the latest, fastest, most efficient charging technology to date. It is designed to charge twice as fast as Quick Charge 1.0 and to be 38 percent more efficient than Quick Charge 2.0. It offers a more granular range of voltages: 200mV increments, from 3.6V to 20V. However, only devices with Qualcomm® Snapdragon™ processors can charge at those faster speeds. More details, please visit: Qualcomm.com

RavPower’s iSmart 2.0 charges compatible devices at speeds up to 5V 2.4A. This is the same speed as told by Aukey and basically what the other charging companies imply when they say “Sends the fastest charge to your device”.

It has ismart for the USB-A, USB-C is Power Delivery. It is compatible with the Macbook 12" which uses 30 watt USB Type C PD.

You can also still find the Anker PowerCore Speed 20000 PD Portable Charger, 20000mAh External Battery with USB Power Delivery (30W), Type-C, if you know where to look.

Generally you will not see QC on USB Type-C because, USB3.1 Type-C already supports Power Delivery up to 100watts.

I was not confusing it, I just didn't read enough of the iSmart page. It does appear that it's limited to 5V as you say. My mistake.
However, the fact remains that the powerbank does not advertise USB-PD as a feature. It seems an odd oversight not to include that in the features if it does indeed have it, as it is listed in the features for the 26800mAh one. You are all free to buy it in the hopes that it does have USB-PD but there's certainly no guarantee that it will charge the Switch at a higher voltage until someone measures the output voltage and confirms that it does indeed supply a higher voltage.
Confirmed, it's using Qualcomm's Quick Charge. Look at the specs:

USB Output: 5V / 2.4A
Max Type-C Output: 5V / 3A
Max QC 3.0 Output: 5V / 2.4A, 6.5V~9V / 1.5A, 9V~12V / 1.2A Max

No hope of this working with the Switch then. It will charge, but you will be disappointed at the charge speed. The Switch won't even use the full 3A, it's limited to 2A only.

Those clearly both mention Qualcomm Quick Charge. It's right there on the page. Only difference is one is an older model that is using an older version of the protocol.
The older one probably isn't even available anymore. Hence why the price is higher, as they lowered the price since the powerbank originally launched.

Most likely a typo, I am emailing them to ask.

It says right on their page it is compatible with Macbook 30W Type C PD

@The Real Jdbye

Your right it does say QC on some parts where others it doesn't I don't think the person listing the specs on it knew what they were doing.

Waiting for email from Rav support, going to get to the bottom of this once and for all lol.

Both the batteries say they support Macbook 30watt. That can't be unless both are USB3 PD. idk.

Wait and see.

--------------------- MERGED ---------------------------

Either way they won't let the 26800mAh on the plane.

Finally found some conclusive info.
Here's some testing done by a person on Reddit using a USB power meter.
https://docs.google.com/spreadsheets/d/1hEgRYI3NztlKbXeVHRpNJ2DbvkOfeeGjIr95x5jADfQ/edit#gid=0
He has tested both 20100mAh models as well as the 26800mAh model, and it confirms what you were saying, that the more expensive 20100mAh model does support USB-PD and provides the Switch with 15V, while the other one doesn't. It's weird that they don't advertise it though. The better of the 20100mAh models will charge at the same rate as the 26800mAh.

Weirdly enough, the Switch seems to only draw 0.5A at 15V. That's about 7.5W, which is roughly equivalent to 1.5A at 5V, and isn't much at all for charging such a large battery. It does lengthen the lifetime of the battery though. Those quick chargers that are all the rage with phones these days are charging the batteries at the limit of their spec, and will cause additional heat and decreased lifetime.
That suggests that there is a whole 1.5A at 15V, a whopping 22.5W reserved for the additional power draw while playing, which is a massive power draw. I can't see the Switch ever consuming that much power.
If it did that in handheld mode it would drain the battery in less than an hour. I'm starting to see why the Switch is so heavily underclocked in handheld mode. It also explains why the thing gets so hot when playing docked.
I'm also thinking that the official power supply is overspecced. Maybe so that they don't have to make a new power supply if they ever make a "New Switch" or "Switch Pro"?

It's too bad he didn't measure the power draw while playing, it would have been interesting to know exactly how much power is used when playing while charging, and the maximum current that will realistically ever be drawn from a power supply, to know exactly how overspecced the PSU is.

His number are weird across the board, even for the actual Nintendo Wall Adapter... They are nowhere in line with the anandtech numbers of whom I would tend to trust a bit more than this guy. At least it's confirms that the 20100 supports PD. That one should be allowed on a plane. Good job finding that, might be a while until Rav support gets back to me lol.

I can confirm that the Anker PowerCore+ 20100 charges the Nintendo Switch in handheld mode (because why would you need to charge it using a powerbank in docked mode?) faster than the battery drains while playing "Breath of the Wild" in handheld mode as long as you use the USB-C port to charge it.

Sorry but even using the C port it does not support 15v2a.

Type C port: 5V 3A; PowerIQ port: 5V 3A max (2.4A max per port)

Update 21 November: Anker has responded to my email inquiry, stating:

I am sorry that the PowerCore+ 20100 is unable to charge 2016 MacBook Pro (15" model) as it is not powerful enough to activate this laptop. We have another external battery which can charge the new Macbook [sic]. Below is the link of this battery:

I checked Anandtech's numbers, and they make sense when compared to his. Remember that Anandtech's numbers are from a powered on Switch running Zelda, whereas his numbers are from the Switch being powered on in the home menu, so Anandtech's numbers will obviously be higher.
Anyway, thanks for that lead, that got me the last numbers I needed to confirm that a bit less than half the capacity of the Switch power supply is never used, at least not by current games. The worst case scenario uses 17.7W, leaving 12.3W of unused power that might be done that way on purpose in case of a future upgraded model with better specs.

It's most likely for powering or charging accessories through the dock's USB ports.

When I looked into this, multiple people stated that the Switch doesn't actually need to charge at 15v when running BotW in handheld mode to not lose more power than it takes in, it only needs to charge at roughly 12v, which the Anker can do.

You might be right. I thought the 5V output of the charger was for that, but it might just use one or the other, not both simultaneously. 3 USB ports at 500mAh each add up to 7.5W which would pretty much max out the capacity of the charger.

It doesn't provide 12V, look at the specs: "Type C port: 5V 3A; PowerIQ port: 5V 3A max (2.4A max per port) "
Moreover, it was tested in this spreadsheet: https://docs.google.com/spreadsheets/d/1hEgRYI3NztlKbXeVHRpNJ2DbvkOfeeGjIr95x5jADfQ/edit#gid=0
The PowerIQ port will not provide the Switch with more than 500mA at 5V, which is to be expected, as it's for a completely different charging standard. But what's interesting is that the USB-C port wouldn't charge the Switch at all. Either he just had a bad powerbank or there is something fundamentally wrong with how that powerbank is designed. Either way, it seems like a shoddy product, and it isn't gonna do a better job at charging the Switch than any of the other 5V@2A or higher powerbanks on the market.

Because they will go by what's printed on the battery and 26800 is 6800 too much...

Thanks for all I'd help and conversation u know more about this than me. I'm just confused I thought to get the max mAh I had to do (100 Wh)/(3.7 V for lithium ion cells) = 27027.027027 mAh? Why is this wrong?

Maybe you should just call the airline and ask the maximum mAh value, not Watt-hour.

If you look at Thai, they list a range of 100Wh(20,000mAh) - 160Wh(32,000mAh).
They are using the maximum voltage of 5v USB, as it states on the bottom of the infograph.

YoshiMoshi · Apr 5, 2017

r right best just to ask. This is here right? https://www.amazon.com/review/R1ADKONG4HIXCH/ref=cm_cr_dp_title written on the back as 99.16 Wh. But best just to ask.

kidasquid · Apr 5, 2017

Most commercial battery packs are rated at battery amperage hour, but you can't rate wattage based on output voltage. They mostly use 3.7v cells inside. 26800*3.7=99.16
