Thank you

i'm sure you have it backwards having both looked it up and tried it lower voltage definitely leads to more heat.In theory lower voltage is better, because that voltage has to be converted to 3.7V anyway to charge the battery, and a higher difference between input and output voltage means more heat is generated. Which is why AC adapters get warm. However the heat generated from that shouldn't be much. Also, the Switch will never draw more than 2A anyway.

It's drawing the same amount of power (watts) or less, and less of it is being lost from heat due to the voltage conversion.i'm sure you have it backwards having both looked it up and tried it lower voltage definitely leads to more heat.
volt is how strong the electricity is and amp is how fast, batteries and wires can handle how many volts they're designed for but more amps means more is going through so more heat.
it's kinda like when thinner garden hoses are attached to high pressure faucets they get all fat and start to crack.
2amps is still almost twice as much as the switch battery was designed for.
it definitely uses 15v, either way you can test the heat yourself just drain your switch some and play it while plugged into your phone charger instead of the intended cable it will get noticeably hotter. amps cause heat volts don't.It's drawing the same amount of power (watts) or less, and less of it is being lost from heat due to the voltage conversion.
The electronics inside the Switch likely don't run off 15V anyway; the difference is just in where most of that voltage conversion happens, either in the charger or in the Switch itself. A higher voltage drop means more of that current is absorbed by the buck regulator, because they're not 100% efficient.
A lot of those 2 amps are not going to the battery (and any medium/high capacity lipo can handle 2 amps fine so you're wrong there, the Switch battery is 4310 mAh and would have no trouble charging at that speed), realistically it's probably more like 1A going to the battery and the rest is only used when the Switch is on. Someone (Anandtech?) measured the power draw in various states and the numbers were around there from what I recall.
Anyway, it's moot because the charging circuit in the Switch will only draw as much as it's designed to.

I don't think it uses 15v... Since the original charger as 2 outputs I'm almost sure the 15v will go for the dockstation motherboard to power the console at full clocks + dock motherboard.it definitely uses 15v, either way you can test the heat yourself just drain your switch some and play it while plugged into your phone charger instead of the intended cable it will get noticeably hotter. amps cause heat volts don't.
I think the 5V output is only used if you use it to charge other devices such as the pro controller. The power draw tests I saw didn't say anything about the 5V on the official PSU ever being used to charge the Switch.I don't think it uses 15v... Since the original charger as 2 outputs I'm almost sure the 15v will go for the dockstation motherboard to power the console at full clocks + dock motherboard.
The other output is 5v 1.5A which is probably what is used to charge the switch undocked which goes right with the charging time of 3 hours and a few minutes.
At 1.5A 3 hours would charge around 4.5Amps, but remember nothing is 100% efficient and all portable devices will reduce charge power when the battery is almost full so near the end the charger and the battery will be less hot since the device drops the charge rate so that the battery makes more cycles and make sure to actually fully charge it.
Even when I charge my RC lipos, even if I chose 5Amps, near the end the battery is already charging at 0.1A so it takes a bit more time. Only if I use the fast charge option it will stay at 5a and end faster but won't fully charge it.
And how do you know that exactly? Did you look up the spec sheet for the Tegra X1 SoC?it definitely uses 15v, either way you can test the heat yourself just drain your switch some and play it while plugged into your phone charger instead of the intended cable it will get noticeably hotter. amps cause heat volts don't.

the switch uses 15v %100 of the time unless plugged into the wrong chargerI don't think it uses 15v... Since the original charger as 2 outputs I'm almost sure the 15v will go for the dockstation motherboard to power the console at full clocks + dock motherboard.

because that's how all electricity works all the time, you learn this stuff in high school. it's not specific to the switch.I think the 5V output is only used if you use it to charge other devices such as the pro controller.

Just because it's being powered off of 15V doesn't mean it's actually using 15V internally, which is what I was trying to say. The internal components are only designed to run off a specific voltage, some of them might be 3.3V, some of them might be 5V, maybe some of them are even 12V like the fan. Likely the voltage coming from the charger is being dropped by an internal buck regulator and going to the main voltage rail, then it's using buck or boost regulators on the main voltage rail to make the voltage lower or higher as needed. That buck regulator will get hotter the more voltage is being dropped. Anywhere else in the system is not going to be affected by different voltages because they're not being fed directly from the input voltage.the switch uses 15v %100 of the time unless plugged into the wrong charger
5v 1.5A is not enough power to charge the switch, it would need at least 1.8amps just to keep it running
if nintendo could have safely included a 5v charger instead of a 15v they would have done it they love skimping out on the little things to save themselves money.
that's probably at least a $8 difference even on the manufacturing level.

i'm not saying it's going to kill his switch it wont. but it will take longer to charge and charge at a higher temperature and will cause the battery to wear out slightly faster.
those are inarguable facts, amps convert to heat; both the longer charge cycles and increased temperature will take it's toll on the batteries lifespan.
it's not going to be a huge difference but if his switch battery was going to last 5 years til it holds a charge noticeably less long with the right charger one charged with a phone charger might last 4.
if he cared enough about his new console to make a thread about which charger to use might as well give him the best answer.


When you charge the console with the original charger and gets to 100% battery, when you take it out of the AC charger and play portable connected to that power bank, does the console stay at 100% all the time?
Yes, it does. It is that good.When you charge the console with the original charger and gets to 100% battery, when you take it out of the AC charger and play portable connected to that power bank, does the console stay at 100% all the time?
I tested yesterday just a bit of Zelda and the original charger kept the console at 100% all time.
Doesn't appear to have USB-PD. For the same price, you can get a RAVPower 26800mAh with USB-PD.
Yes, it does. It is that good.![]()

I hope it is goodYes, it does. It is that good.![]()
You have info here about power banks:My last couple of questions were over looked so I will try you seeing as you kindly linked us to your blog post
Do you think the Anker charger I own that I linked in the OP will give me the same results as you are achieving OR is the amps / volts / watts etc.. etc.. all totally different ?
I got a discount from ebay, I did not pay full price. The link was only for people to reference where to buy the product, not reflect my price paid for it. Thank you for the information though, I was looking for one that holds bigger charge.Doesn't appear to have USB-PD. For the same price, you can get a RAVPower 26800mAh with USB-PD.
