TNTOR Thin Portable Phone Charger with Built in Lightning Cable-3500mAh Ultra Slim Travel Power Bank for Pocket Wallet Compatible with iPhone 14/13/12/11/X/8 Series (Not for iPhone 15 16 Series)

These are nice compact battery packs that can fit in a pocket. They work great with out phones so we don't have to worry when we are out for a day.

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!

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.

This is a decently portable, emergency back up 3500 mah charger to carry with you on the go in your jacket or carry in a bag. However, it is bulky to carry in your pants pocket if that how you daily carry an emergency charger. Think about half the size of a typical modern Android phone, only thinner.A while back I purchased TNTOR's earlier PowerCard 2500 mah version with native micro-USB charging which was a fantastic size as a pocket charger; which at time of this writing is no longer available on Amazon but the 2500 mah Lightning/Apple charger version continues to be available off Amazon. This 2500 mah version was the perfect sized but unfortunately lacked native USB-C charging to make it the perfect pocket emergency charger. Think about slightly larger & thicker than a credit card. If you have an iPhone though, get that earlier 2500 mah version if you want something more discrete & portable.This newer 3500 mah version fortunately does have native USB-C which means you don't need to attach a separate micro-USBC adapter (like the earlier version). You do get an extra 1000 mah charging power in this newer version but at the cost of the smaller size. Really wished they brought back the earlier 2500 mah version & size and paired it with native USB-C charging. At this same price point, it would be the Goldilocks of pocket chargers :)

This thing is so convenient and slim

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.

I received a similar one of these for Christmas from my in-laws and loved it. It was exactly credit card sized. My mom loved it so much I looked it up and found out the one I had was extremely expensive.We ordered this one to see how it compared.It works great! First off it's not as small and compact as the other one but it's still incredibly thin compared to the majority of chargers. You can absolutely carry this around with your phone no problem.Secondly it has more charge then the smaller one so that is a bonus!Would absolutely 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.
