I Used to Think Power Banks Were for People Who Couldn’t Manage Their Day. Then the Power Went Out.


I'll be honest: for years, I looked at people carrying power banks the way I looked at people who brought pillows on short flights. Really? Is it that bad? Just charge your phone before you leave the house. It's not complicated.

Then we had a power outage.

Not a two-hour blip - a real, extended blackout. Hours in. My phone was at 18%. My laptop was dead. I had calls I needed to make, people I needed to reach, and absolutely nothing to charge with. I remember sitting there thinking, okay, I get it now.

The next day I went looking for a power bank.

What started as something I bought for emergencies ended up being more useful than I expected. I still don't think everyone needs to walk around with one in their pocket all day, but I've completely changed my mind about having one available.

Why I Now Keep a Power Bank Around

The obvious reason is backup power. A blackout is an extreme example, but there are plenty of less dramatic situations where having your own battery is useful: a long day away from home, traveling, a phone that's draining faster than expected, or simply being nowhere near a convenient outlet.

For me, the important distinction is that I don't treat a power bank as something that excuses me from charging my phone. It's backup. Most days it sits unused. But when I need it, I'm very glad it's there.

I've used mine on long trips, during a dead laptop emergency, and to rescue another phone when there wasn't a charger nearby. It has become a little like keeping a spare key around - mostly invisible until the moment you need it.

What I'd Look For in a Power Bank

After actually living with one, there are a few things I'd prioritize if I were buying again.

  • Enough capacity: I like the 20,000mAh range. It's large enough to be genuinely useful for several charges without becoming an enormous battery pack.
  • USB-C input and output: I don't want to carry a special cable just to recharge the power bank itself.
  • Fast charging: The point isn't just how much energy the battery stores. Being able to put a useful amount of charge into a phone in a relatively short time matters.
  • Multiple outputs: Being able to charge more than one device is surprisingly handy, particularly when traveling.
  • Reasonable size and weight: There's always a trade-off here. More capacity means more battery cells, and more battery cells mean more weight.

I wouldn't automatically buy the model with the biggest capacity or highest wattage. I'd buy enough for the devices I actually expect to charge.

There's Also the Public USB Question

A few weeks after buying a power bank, I came across a video about the potential security risks of public USB charging stations - the ports you sometimes find in airports, hotels and other public places.

That gave me another reason to carry my own power source. If I have a power bank, I don't need to connect my phone directly to an unknown USB port. I can use my own battery and my own cable instead.

A simple rule I follow

If I need power away from home, I'd rather use my own power bank or my own charger connected to a normal electrical outlet than connect my phone directly to an unknown USB port.

That's not the reason I bought a power bank, but it has become another reason I like having one with me when I travel.

What I Actually Use

My Baseus 20,000mAh Power Bank

The power bank I actually use is an older Baseus 20,000mAh model. I've had it for quite a while, and it has been reliable enough that I haven't had a reason to replace it.

The capacity has turned out to be a good compromise for me. There's enough energy available that I don't have to worry about conserving every percentage point, but it's still something I can throw into a bag when I need it.

The main downside is exactly what you'd expect from a battery this size: weight. A 20,000mAh power bank isn't something I want permanently in my pocket. For a backpack, travel bag, car or emergency drawer, though, that doesn't bother me much.

I tried to find my exact Baseus model again, but it's an older model and I couldn't find it for sale anymore.

A Current Alternative

Baseus MagSafe Battery Pack 20000mAh

20,000mAh  ·  Magnetic Wireless Charging  ·  20W USB-C PD

Since I couldn't find my exact model, I looked for a similar current Baseus power bank instead.

The closest option I found is the Baseus MagSafe Battery Pack 20000mAh . It keeps the same 20,000mAh capacity and 20W USB-C charging while adding magnetic wireless charging for compatible iPhones.

I haven't personally tested this exact newer model, so I don't want to present this as a review of it. My experience above is with my older Baseus power bank. This is simply the newer, similar option I found when looking for something that's actually available today.

The Bottom Line

I still don't think a power bank is something everyone needs to carry everywhere. Most of the time, charging your phone before leaving home works just fine.

But I've stopped thinking of a power bank as a gadget for people who can't manage their battery. I think of it as backup power. It sits there doing nothing most of the time, and that's perfectly fine. When something doesn't go according to plan, it's there.

It took a blackout for me to figure that out.
