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

Works exactly as described. Charges my Galaxy phone about 40-45%. It does not charge fast (nor does it claim to do so). It is best described as an emergency "top off" until you can get to a better/faster charger. Super thin and lightweight, perfect for my needs.

This is my "carry everyday, use occasionally" power bank, and for that it's absolutely perfect. This isn't my go to power bank, but it's the one I have with me when I forget my normal one. It fits the outside pocket of a chums surf short wallet like it was made for it. It's been reliable through years of sitting on it and carrying it, the design fits a 2,500 mah lipo which is more than enough for occasional emergencies, it has a USB male but also a USB female that is in/out which can be used to charge other devices as well. It charges slowly, but this is actually a feature not a bug, if you try to charge too quickly you end up overheating and with a design this thin that would have a negative impact on battery life. I find myself buying more than one just in case they decide to discontinue it, that's how unique this is at the price point and size. Get one to complement your normal power bank!

easy to use, charges well and will charge your phone to about 75%

Great portable power source to charge your phone in an emergency. It's small enough to fit in your wallet. My only problem is that it's kind of slow in charging and doesn't fully charge your phone. It's still great in an emergency because it does charge your phone enough to use it in a few minutes.

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.

Great small charger. Fits easily in your wallet.

This does not have enough power to recharge 1 phone. I bought 2. When my phone was at 38%, I plugged the 1st, fully charged charger and after more than 2 hours, my phone was only at 73% and the charger was spent. I thought that it was just a fluke with the 1st, so I repeated the process with the 2nd charger with the same results. Very disappointing.

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.

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

I've been waiting for these small units to become affordable, and they finally have. This one has the advantage of having the usb-c cable built into it. It gives me a couple of hours use of my phone if I forgot to charge it. It gives me time to get back to a charger, so I'm never out of power. I carry it in my pocket all the time, and I'm barely aware it's there.

Small and compact. Will easily fit in wallet.
