This card-sized MagSafe power bank just hit its lowest price yet: $34

The tiny Baseus Picogo MagSafe power bank is on sale for $34 right now, a big drop from its original $70 and even its street price of about $45. But with the extra 10% off “brand promotion” on Amazon, this power bank is now down to a new low price—a great time to grab one.

About the size of a credit card and 0.5 inches thick while packing a 10,000mAh capacity, this power bank is super portable without sacrificing charge. It’s wireless-capable and magnetic, so it snaps onto the back of your phone and keeps it charged. With that 10K capacity, you can fully charge most phones about twice—not bad for a day, though you’ll have to contend with its 0.375-pound weight.

It provides 15W of Qi2 MagSafe wireless charging as well as 27W of wired charging via the USB-C port, so if you’re in a hurry and really need to top up a device fast, you have the wired option. Otherwise, for day-to-day peace of mind, that 15W wireless is more than fast enough.

All in all, this is mainly a phone’s power bank that can also charge stray accessories (like earbuds) in a pinch. It’s not the right choice if you need a power bank that can handle your laptop or one that can charge a full family’s worth of gear simultaneously. You’re mainly paying for the wireless convenience, and it’s worth it now that it’s $34.
