Everything runs on batteries these days, which is why I have more than one power bank.

Here’s why you should, too.

There are endless tech accessories, many of which you’ll likely regret buying.

But when it comes to portable power banks, the more the merrier.

We’ve all experienced that anxious feeling after noticing a battery is about to die.

In fact, a power bank could be a lifesaver in an emergency or power outage.

You’re all set if you have a power bank and a compatible charging cable.

As a bonus, they’re also great for helping friends and family.

It’s a win-win.

However, that doesn’t mean you shouldn’t have a power bank or two.

I own upwards of ten, even if one or two are slightly older models reserved as a backup.

With enough power to charge multiple gadgets with USB-C PD fast charging, Anker’s PowerCore Slim 10,000 will keep your iPhone or Android topped off while on the go.

Portable chargers (aka power banks) have a wide variety of uses.

It’s not just about mobile devices, though.

Now that’s useful!

I find that 10,000 mAh power banks are the ideal size.

More importantly, they’re lightweight, thin, about the size of a smartphone, and affordable.

Another solid option is one of the many 20,000 mAh power banks from Anker, Mophie, or UGREEN.

We recentlyreviewed the UGREEN 20K power bank, which delivers 100W of output power.

It’s strong enough to run a MacBook and Nintendo Switch or charge multiple mobile devices.

They’re Cheap and Effective

We’re all feeling the pinch on our wallets these days.

They’re handy for day-to-day activities and perfect for emergencies.

I always have one charged up in every vehicle, just in case.

You never know when you’ll need it.
