Nice little portable charger
on August 26, 2026
Posted by: NathonC
[This review was collected as part of a promotion.] The battery lasts a good while and was able to charge my phone all the way. I dont have a magsafe case but it still holds to the back of my phone. I ended up taking the keychain part off but the charms are cute. I do like that it is smaller than a lot of the other battery boxes ive had. It also came with some stickers! Overall Would recommend

The cutest power bank I have seen.

[This review was collected as part of a promotion.] It's very easy to use. This power bank was designed to be tiny and comfortable on the go. The charger holds very well, and it is lighter than other products. However, the problem is that it heated up while charging the phone. The charms and stickers are cute for customization.

Great charger

[This review was collected as part of a promotion.] This is such a cute battery pack charger. This thing will charge an iPhone fast. We have iPhone 7/8 and 15/16 and it will charge them all. It’s great for on the go in the car or out and about.

Not worth the money
on August 6, 2026

[This review was collected as part of a promotion.] This is the lightest power bank I have ever used, but the least intuitive. It is very pretty. As you can see, it comes with accessories and stickers, but the charging plug didn’t even fit correctly or work, so I ended up using the charging cord for my iPhone, and another adapter I already had, because it wouldn’t charge from my computer; only the wall. The instruction book is practically useless, and I couldn’t find much information online. I googled the device and found out how you can tell when it is turned on and off. It apparently turns itself off when it is not in use, and turns on when you connect something to it. The problem with that is that if you turn it onto the charging side and leave it on the table, it will think that it is on, or have it in your bag pressed up against something. It was fully charged one day, then I went to use it the next, and it was 29% even though I had not used it. It does not charge very fast, and so, I would only be using it for trips, and when I am out and about, but if it turns itself on in my bag, and loses a charge that quickly, I’m not sure how useful this one’s going to be for me. My phone didn’t charge past 80% with this device, even though it goes to 100% with every other charger I use, so this is just for when it gets low. When my phone was around 50%, it took about an hour and a half for to get to 80%. It was quite warm, so it was working hard. I was surprised to see what price this is going for. I don’t think it is worth the money.

If you are a power user, this may not be for you. This is a cute and compact “nice in a pinch” option but not a heavy use item

[This review was collected as part of a promotion.] This battery pack is very cute. My daughter loves the packaging, the look, the stickers that came with it, and especially the lanyard bracelet thing it comes with. It is very portable and compact. The tiny USB-C cable that comes with it is nice as well to keep in a little purse.

Such a cute compact way to seamlessly charge your phone!
on August 1, 2026
Posted by: AliciaL
[This review was collected as part of a promotion.] This is the absolute cutest power bank I have seen! I love the color, the beads, and the cute compact size. The weight is overall light and seamlessly magnetizes to the back of my phone. The charging seems slightly slower than one other that I have used in the past but definitely still charges. I do also notice some heat coming from it but nothing alarming. I love caring this around just in case my phone needs a boost! I would recommend!

Perfect for maintaining phone charge.

[This review was collected as part of a promotion.] The iOttie with BT21 Veloxhas a compact stylish design for your on the go charging needs. This durable design will standup while I wondered about the capabilities of using my device while charging it seems to slow the process.Heat produced while using is minimal and is low maintenance.

Super cute and easy to use!

[This review was collected as part of a promotion.] Sure cute and very useful! Holds a charge really well and is just the most adorable accessory! Comes with stickers and a charm to decorate with. Very easy to use. You can magnify it to the back of your case or plug it in.
I love how customizable it is! And it comes with a fun little Photocard of one of the bt21 characters. I got Koya!
