How can I effectively use a portable power bank to charge my devices on the go without draining my phone's battery first?
I've recently started traveling for work and I'm finding it's becoming increasingly difficult to keep my devices charged. I've invested in a portable power bank thinking it would be a lifesaver, but I'm not sure how to use it efficiently. I've noticed that when I plug my phone into the power bank, it often drains my phone's battery before actually charging it. This seems counterintuitive to me. Can someone please explain how to use a power bank in a way that maximizes its effectiveness? I'm also curious to know if there are any specific power banks on the market that are designed to address this issue.

I totally get your frustration, it can be really annoying when you're on the go and your devices start running out of battery. I've been in similar situations, and I've found a pretty simple solution. The key is to use the power bank in reverse - plug your phone into the power bank when it's already plugged into a wall outlet or another power source that's charging it.
This way, the power bank will actually start charging your phone without draining its battery first. It's a bit counterintuitive, I know, but it makes sense once you think about it. When you plug your phone into the power bank directly, the phone's battery is being used to charge the power bank, which is why it seems like it's draining the battery before charging it. But when you use it in reverse, the power bank is actually just a conduit to get power from one source to your phone.
If your power bank has a built-in switch or option to switch between charging and discharging, make sure to use the charging mode when you're plugged into a power source. Some power banks also have higher input currents, which can help charge your devices faster. Look for power banks with high input currents (usually around 2A or higher) and built-in switches that let you control the charging mode.
