can I charge my Acer Aspire A515-58GM-74CC laptop with a type c outlet power bank?

my laptop battery drains out very quickly. within an hour of usage without plugging in and that becomes a problem in my uni where I have to keep my laptop charged atleast 4 hours before I could charge it again at the charging station.

and so i was wondering whether I could use a power bank to charge it while it's in idle mode during breaks. my laptop has a DC charging input but supports Thunderbolt 4, idk if that's of any significance. i tried getting a DC adapter as well but it didn't really work out, although I got the correct port size (3.0mm x 1.1mm) the adapter's pin length becomes an issue.

if it helps, I'll add my model number as well as a photo of my type c, DC and type b ports.

model number : N22Q25 (2023 model)

Hi alankrit91107, Your Aspire A515-58GM technically supports Thunderbolt™ 4, which means the i7-1355U CPU is capable of handling Power Delivery (PD), DisplayPort Alt Mode, and PCIe tunneling. However, Acer’s implementation on this model appears limited, especially when it comes to charging over USB-C.

Many users have found that:

• The USB-C port offers data transfer and display output, but not reliable charging, even with verified 60–100W PD gear.
• It may only support up to 15W (5V 3A) — fine for accessories, but insufficient for keeping your laptop running.

⚠️ Just to clarify: While the CPU supports Thunderbolt™ 4 across the board, OEMs like Acer can choose to disable or restrict PD features at the motherboard or firmware level, likely for cost and thermal control reasons. So yes — your laptop could support PD in theory, but in practice, it seems Acer chose a more limited wiring.

Your best bet is sticking with the barrel jack and maybe investing in a portable DC power bank that matches the input spec (careful with pin length!). Alternatively, if your university setup allows — meaning you have reasonable access to wall sockets during class breaks — bringing your laptop’s original AC charger can be a more reliable way to top up the battery than relying on limited USB-C PD.
