Hello, I'm looking for a power bank for my XPS 15 9570 as I'm gaming and editing videos quite often on it, depleting my battery quickly. When I plug in a USB-C phone charger, it says my computer needs at least a 45-watt charger for it to charge. I spoke with a Dell customer representative and they told me that I need a charger of atleast 130W to charge my laptop, and recommended me this: https://www.dell.com/en-us/shop/dell-notebook-power-bank-plus-18000-mah-pw7015l/apd/451-bbkv/pc-accessories. Looking at HWiNFO, my laptop is using 43W on charge, are they lying to me? If so, can anyone help me find a power bank that I can charge overnight and use on the go? I currently only have one charger that I keep at home, and I'm too scared to take it with me as I'm afraid to lose it. If a power bank isn't available, I'm okay with a charger as long as it's able charge my laptop from the nearest outlet.
Thanks.
Here is my HWiNFO
