Compact, powerful and cute!

[This review was collected as part of a promotion.] This charger is tiny, it folds up and easily slips into a pocket or purse. We keep it in the kitchen for quick charges throughout the day. It has one USB C port, and with a good cable my phone shows fast charging and usually gets a full charge in under an hour. My daughter was so excited about the BTS photo cards and stickers.

[This review was collected as part of a promotion.] I really like this charger because it’s small and powerful. Since it’s USB-C, it’s capable of charging multiple devices and the charger itself feels very premium.

Convenient for an extremely fast charge

[This review was collected as part of a promotion.] This is a great wall charger for when you need an extremely fast charge! My only concern was the wall charger got extremely hot when charging my phone, but I had no issues with overheating when charging my video game controller. As long as you have a usb-C/C at home to plug into this wall charger, I'd definitely recommend this wall charger for whenever you need a really quick charge. It also came with a really cute card and little decal stickers. I also really like that the plug flips in and out for easy storage.

[This review was collected as part of a promotion.] Super cute charging block. I love how you can add stickers to make it personalized. It is easy to set up and use. It charges my phone quickly. It was easy to find a cable to fit the block.

[This review was collected as part of a promotion.] This is so cute! It didnt come with a cord so I used one i already had. It did however come with some cute stickers that I put on the brick. It works great and chargers up my S26 Ultra in no time.

Adorable with great performance
on August 7, 2026

[This review was collected as part of a promotion.] This is the cutest wall charger I’ve ever seen. My teenager keeps trying to take it to her room because it’s so whimsical, a buttery pastel yellow with lavender stars on it.
Directly out of the box, the wall adapter is ready to use. Plug it in to the wall and attach a USBC cord of your choice to being charging your device.
While it wasn’t billed as a so-called fast charger, I find that its performance exceeds what I have come to expect from a solid anker or belkin wall adapter.

I used it first to power up my notoriously slow to recharge anker power bank. Even on my Apple ac adapter and cord it takes up to ten minutes of charging to reach 1% once the power bank is at zero. Four minutes after plugging it in to this little cute and my slowpoke power bank is at 2%!
I’m a huge fan of this adorable wall charger.
