TNTOR Thin USB-C Portable Charger with Built in Cable, Slim Power Bank Credit Card Size Battery Pack Charger Portable for Wallet Compatible with iPhone 15 16 17 Series, Samsung and Android Phones

For its size and slimness, this is an excellent charger. It is very light and very slim. It charged my Samsung S20 from 5% to 50%. which is good for such a tiny charger.

This portable charger is awesome. The slim design makes it easy to carry around in your wallet or purse and it charges your phone fast.

I have Absolutely great. This is connected to my iPhone. By a Mag ring.to my case. I now will never worry about my battery running out on my airline flights. I have this thin , light, backup battery. When I foolishly forget to charge. So, convenient.

I bought this last summer and have been using it quite a bit. Did a great job charging my phone when I was low. Small enough to fit in my wallet and light enough to have it charge and use my phone at same time. I bought 4 more for my people as Christmas gifts. Made me look like a hero.

A great size to carry to recharge your phone or IPad. It works great

A cool little device. Handy to keep your phone battery charged. Slim and easy to carry.

Trash!

I recently purchased this slim battery pack, and I must say, I'm impressed with its design and functionality. Its slim profile makes it incredibly convenient to carry around, whether I'm charging my phone on the go or simply holding it in my hand. Plus, its compact size means it fits seamlessly into any pocket or bag without adding any extra bulk. However, it's important to note that while the battery is great for quick charges when you're running low on battery, it does have its limitations. It typically only charges my phone to about 50%, so it may not be suitable for long-term charging needs. Despite this drawback, I find the slim battery to be a convenient solution for staying powered up on the move.

These credit card-sized chargers are fantastic if you're worried about running out of battery at the end of the night and need to call an Uber, or for any other reason. It's compact and convenient, avoiding the need for a bulky power bank. Note that it's only 2500mAh, so it won't fully charge your phone, but it provides enough power to get you through a few more hours, depending on your usage. The charger is about the width of five credit cards and a centimeter or two longer than a credit card on either side. I've had a similar "credit card" charger before and loved it. It was perfect for traveling or attending a day-long festival when I didn't want to carry too much. This charger slips right into your pocket and is a lifesaver when your phone is about to die, and you need to contact someone or find your way home. My old one was from a brand called "TravelCard" and had a smaller capacity of 1500mAh. This new one is significantly larger at 2500mAh, but the physical size is almost the same. I appreciate that it has both USB-C output and input, as I'm tired of devices that still use micro-USB. I've only used this charger a few times so far, but my only complaint is the charging time. One review mentioned it took 24 hours to charge, which I found surprising. I timed it myself, and it took around 3 hours, which is still quite long for a 2500mAh battery. However, it charges my phone at a decent speed—no super-fast or fast charging, but regular speed, which is acceptable. Lastly, this charger is the best-priced option I've found among similar products. Other brands like TravelCard charge $55 USD for their 3000mAh version, and the Clutch Charger is around $70 USD. It's great to find this one at less than half the cost of the others.

Love the size, charges fast, can get a little warm. Wanted to purchase more and won’t ship to my location now?

This thing fits in my wallet and can give me half a charge - maybe 10% of a charge for my MacBook Air in a pinch. It's good to have and something I can carry on me at all times. It's a nice safety net. It took a bit to fully charge but I dont care as long as it does its job

Small and compact. Will easily fit in wallet.

It’s cool! Great back up power supply. Just in case.
