I bought a power bank online from a trusted store back in March and everything has been fine until I noticed a crack forming along the light and battery indicator. I initially ignored it, thinking it was due to mishandling, but now the crack has gotten longer. I'm wondering if it's still safe to use this power bank. It doesn't overheat when I charge my phone, but I'm worried it might explode. Should I get rid of it? Here's a picture for reference: https://imgur.com/a/CNcvZLm

You could try putting some tape over it for now, but definitely keep an eye on the temperature while charging. If it feels hot, it's best to stop using it. Safety first!
Returning it to the original shop might be a good idea. They might have a warranty or recycling program. Just in case, don’t leave it unattended while charging, and refrain from using it while you sleep.
That crack looks like it’s just in the casing, and it probably doesn't mean the battery is swelling. Still, be careful! You definitely shouldn’t just toss rechargeable batteries in the trash since they can cause fires. Look for a local recycling or disposal site instead.
If I were you, I’d think about tossing it, especially if there’s a chance the battery might be bloating. You don't want to risk it bursting. A good rule of thumb is to avoid leaving the charger connected for too long and keep the battery out of extreme temperatures.
Honestly, if there's a significant crack that might let moisture in, that's a possible risk. You could seal it up with some electrical tape if it’s safe enough, but it might be time to consider getting a new one.
