TNTOR Portable Charger with Built in USB-C Cable Ultra Slim Credit Card Size Power Bank for Pocket Wallet Battery Pack Compatible with iPhone 15 16 Samsung, Google etc

Love these chargers. They a very thin and compact and literally can fit in your pocket with the phone while your charging. Very handy!

Very handy power bank. Attached cable very convenient and tidy. Holds a good charge quite a while. Easy to pack!

Recharges quickly enough and charges even faster. Not a "super fast charge" but I'll take the weight savings over the electronics that would be needed to make super happen. I plan to use this when traveling, taking photos and videos, and expecting to be away from a charger all day. At the end of the day, you can have this charging while it charges your phone so that when you wake up both are full. After letting it sit full for a couple days this little device took my S24+ (4900 mAh battery) from 25% to 72% with the phone on but not in use. This is 47%, or 2300 mAh, added to the device, meaning it's 65% efficient in getting the power in the pack into the phone - or in other words a 35% loss. This is consistent with Anker's nano power bank they explain it as follows "The capacity reduction during charging is due to a 30% to 45% energy loss in the battery cells and conversion circuitry."This sits nicely in a pocket with phone, just have the USB port facing down so the weight of the pack doesn't pull on the port. I like the design of this device over the anker because it's flatter, will sit nicely under a wallet, and doesn't weigh on the USB port. I would go with this model over a similar smaller model I saw because 1) this is already incredibly small and 2) this one put out more watts for a faster charge.Only complaint is the cord is a little tight, it's tough to get back to its dock.Highly recommended, just get it. This is the perfect portable emergency backup!

Charged works as advertised. I love the pocket size- it is about the same width as my iPhone 12 and not as tall, super thin, so it fits really easy in my pocket or my wife’s purse. The two reasons I gave it 4 stars instead of 5:1) Charging cord can be finicky. Sometimes my iphone would not recognize it and it would not begin charging. Most of the time it is good though.2) It takes a little longer to charge your phone (not an eternity, but it’s definitely not “fast”). I have an iPhone 12. I purposefully drained my phone to about 4% and made sure the charger was fully charged to 100%. For the charger to get the phone from 4% to 92% was about 2 hrs. To get my phone to full 100% took exactly 2.5 hrs.Definitely good for emergencies when you’re out and about but not for “fast” charging.

We bought this portable power pack with a built- in cable to recharge our smart phone or tablet when we sre on the go. It’s credit card-like size fits nicely in a purse or pocket and should be durable. It’s a bit heavy but manageable. The built-in cable is a big plus.

I use this as a quick and light charger when i know i will be out and about all day and may be using my phone. Used it several times at theme parks and worked well. Granted the charge it can hold is limited due to its size, but the usefulness of being able to just have it on me is so nice. Makes for a nice easy battery backup where size and weight matter. Charges back to max fairly quick and has 4 led lights on the front to show overall power level and when charging they will start to blink as it charges back up. No heat issues thus far and would recommend this product for its cost and size.

This works wonderfully for the majority of my daily needs in a phone battery pack.It is very thin and light. A little larger L & W than expected, but still smaller than my phone (pixel 4).It holds enough to charge my phone about 80-90% once, which is plenty for me in most cases.When plugged in, the cable routes well and the battery is then easy to hold nestled behind the phone in one hand. Fits well in a pocket as a result.Great buy! Highly recommend.

UPDATE: It says its 3500mah, but its actually around 3/4 of that or around 2500mah. Spoke to the seller and they confirmed it as well.- It has a on/off button, but cant be turned off. It stays in a sleep mode. Essentially wasting power even if it may not be much.- Also takes really long to charge completely. Around 5 hours which is horrendous for the capacity it has.Super slim. Easily fits in front or back pockets. Slightly longer than a credit card and around 1/4 the thickness of a common smartphone.Made of some sort of metal.Has 4 led lights that show the battery status. Each led represents a fourth of the battery power. 25% - 100%.Has a power button.The bank has a type c cable that is really snug and discreet already attached. No need to carry a cable.Makes it real easy to hold the phone and powerbank at the same time. Its slightly noticeable.Comes with a male usb a to male usb type c.Charges in around two hours.
