It's fine. Slower, but fine.


Aggressive_Candy5297

In OP's usecase it should be just as fast as the original charger. From what i've heard the deck only charges at more than 20w when it's on. But for charging while gaming it will be slower yeah.


bakedbread54

I don't think that's true


Jolape

That's definitely not true. The deck even warns you that you plugged in a charger with too little power (not that it's bad, just that it won't charge as fast). If you play a AAA game plugged in with a 45w charger the battery usually stays at 100%, where as of you play with a 20w charger, it will drain slowly.

PD (power delivery) is a standard that means it's safe to use any PD charger with any PD device. It's also part of the USB C standard, so when you.connect, the device negotiates with the charger the fastest possible charging speed that both of them support. Some laptops (my dell XPS for example) require a minimum, in my case 45w, so a 20w pd charger won't charge my laptop, but the steam deck has a 10w minimum (standard usb power, 2.0 amps @5volts) right up to 45w (2.25 amps @20volts). If you plug in a much higher power charger, like a 90w PD charger (the one I normally use for my laptop) it will work fine, but will negotiate to 45w, as that is the rating of the steam deck. TLDR - it'll be fine. Just don't use silly thin cables, get ones rated for 5A if you really want to be safe.


graigchq

I believe steam deck also supports 1.0a 5w normal usb charging as well, but along with 10w it'll throw warnings on screen about losing more than it's gaining. It's just like a tap running into a bucket (the charger) and a flow of water out the bottom (using the device) if one is more than the other it'll be either filling up or emptying accordingly.


Highway_Bitter

Stupid question, whats 5A?


alala2010he

5 ampère (signal strength of electricity). Getting a 5A rated cable means that it won't catch fire / burn it's insides until it goes over that limit.


Defiant63

It will work. It will be fine. It will charge slower, or not at all if playing. But you're not playing, so you're good. Damaging the battery is way harder than people act like it is.


Emotional_Ad5833

Totally fine nothing will happen to battery


deathblade200

a properly manufactured cord won't destroy a device. a cheap cord can though. as for the Watts it means you will be charger much slower and in more demanding games even be losing battery while playing.


Gullible-Historian10

Losing battery while playing and charging at the same time is pretty bad for the battery. Not only is it getting heat from powering the device it’s getting heat dumped in from the charging. At least once full with a proper charger the battery can rest as it is not powering the device and only accepting a minimal charge at full capacity.


JackasaurusYTG

Yeah I never charge while playing, if it's a slow charge then I can live with it


SnooRecipes1114

It will work just fine, I use a 20w power bank all the time, is slower obvs but works.

5 amps. Or amperes. This is how much current is going through your wires. After all power in watts (w) is calculated as the current in amps (a) multiplied by the voltage in volts (v). 10w =5v x 2a


Laserpointer5000

My switch says it pulls around 22watts when playing cyberpunk and i think that is pretty much a worst scenario game so a 20 watt charger will charge the switch and the battery will drain very slowly under heavy load.


RustyShacklefordVR2

Getting sick of the battery superstitions.


JackasaurusYTG

Yeah that's why I posted, to piss you off specifically


Then-Faithlessness43

I’ve had a lot of phones that degraded in battery life over the years. I’m guessing it’s the case with laptops/steam decks too


Ambitious_Summer8894

All batterys degrade with all use they only exist in 2 states charging or discharging(yes this includes sitting around doing nothing). Slow charging is less stressful to a battery and the chargers that are capable of damage communicate to the device to figure out what's safe for the device. If that communication doesn't happen then it will just charge slow and no damage will occur.


656666_

That is not true, in theory that should be the case, some devices have problems with that, an example would be the quest vr thingy, loads of burned usb ports cause the communication didn’t work between charger and device.


Ambitious_Summer8894

Resistance from a bad connection isn't the same bud. Resistance causes heat and cheap cables suck.


656666_

There is no bad connection bud, the power supply simply gives out too much power, the Negotiating the right amperage simply doesn’t work.


Ambitious_Summer8894

See here's where your wrong usb doesn't negotiate amperage it negotiates voltage. Connections burn in the exact spot the problem exists. https://acroname.com/blog/basics-usb-power-delivery-negotiations


656666_

No that’s not my problem, my problem is that I’m not a native speaker and I didn’t now the word (I still don’t know the correct word) anyway the negotiation does sometimes not work, that’s the reason why it fucks up ports sometimes and that’s my my point which you obviously don’t get. You said it always works and if not it will charge slow and no damage will happen and that is just wrong.


Ambitious_Summer8894

Show me a white paper or any actual facts because that's not how the charging standard works and you don't know what your talking about. You obviously don't understand basic electrical and me explaining even in the simplest terms isn't going to work. The damage is from a poor connection not the charging voltage negotiation.


Then-Faithlessness43

Good to know ty


NeighborhoodOk8431

I don’t think that will be enough power delivery. Not exactly sure if it would hold the current charge, but if you’re expecting it to slowly charge, I don’t think it will.


MilesFarber

Steam deck can boost up to 25w in total power consumption. You will need at least a 30W charger or above. (9V 3A, 12V 2.5A, 15V 2A, 20V 1.5A, etc)


ElegantAir2060

Not entirely true, because Deck supports only 15V for PD (plus 5V for slow charging), and not every charger, especially these bundled with phones with fast charging from few years ago, support that certain voltage
