    Product seems to function well when tested but I’ve not needed to use it as yet but will on my future travels! I like that it is a small pocket size item, rechargeable and convenient for any emergency charging needs.

    I purchased 2 of these and the battery banks are okay. It does as advertised. I'm running my Note 20 Ultra and from a depleted charge @ 20%, it came out @ 80%. So a little lacking @60% charge before the bank is dead. Ma gripe: Does not charge my Fitbit Inspire 3! Both banks recognizes the Fitbit then turns off after 60 seconds! Too little power draw and powers off!

    No stars I’m giving. From day one it has not been working and out of the box it had been charged half way. When it was at 1 blinking light I attempted to charge it but it did not hold a charge. A waste of money. The company needs to stick with making batteries.

    Very slim and lightweight, perfect for travel or keeping in a pocket. Charges my phone quickly and I like that it can handle multiple devices at once. Build quality feels solid and the finish looks sleek. Definitely reliable for day-to-day use.

    This is really a great device. I used it to charge my iPhone from about 20% battery left and it seemed to only use about a quarter of the charge capability of the device. (Assuming the light indicators is representative of the charge life left). It’s easy to carry. Can charge more than one item at a time.

    The small portable charger I recently got is great! especially during my runs. It's compact and lightweight, making it unnoticeable in my pocket. Despite its size, it efficiently charges my devices quickly and has multiple ports for charging multiple devices simultaneously. It's durable and reliable, lasting throughout the day without needing an outlet. It seamlessly blends into an active lifestyle.

    This battery pack is a lifesaver! It’s compact enough to carry anywhere but packs a serious punch. The USB-C port works as both input and output, and the two USB ports are super convenient. Great for keeping all my devices charged on the go.

    Nice Portable Battery that lasts the whole day without having to worry that my device won't have battery. Wish this came in other colors, and that it was a bit smaller or flatter.

    The right size for an emergency power bank

    This is a flexible little power bank. Lightweight and slim. I took it on a short trip and was able to recharge a phone. The charger was fast and the there's plenty of options with two A and one type C port. From my experience you'll probably get about two full cell phone charges from this battery and that's enough for emergency or travel use for me. Highly recommended.
