Set Alert for Product: TNTOR Portable Charger with Built in Lightning Cable, Credit Card Size for Pocket Wallet Power Bank Compatible with iPhone 14/13/12/11/X/8 Series (Not for iPhone 15 16 Series) -
Very thin, not for rough handling. I love the thinness of this powerbank for emergency charging. Useful when I’m out on the trails for 5+ hours and using the maps on my phone drains power. It’s very slim so it doesn’t take up much space in my running vest pockets, and the attached charging cord is convenient and also doesn’t take up space. However, because it’s so thin, it feels fragile, so I have to make sure I sandwich it between items to protect it. When I’m not out on the trails, I keep in in my hip bag/wristlet. I hate carrying big, bulky purses, so this slim powerbank is perfect. It fits in the inner pocket with my ID and debit cards. It’s a bit fragile for everyday use (I’m hard on my gear) but good as backup.
Perfect for pocket carry. This power bank is a vital part of my backup power strategy. It’s always in my pocket when I go out. I have 5000 and 10,000 mAh banks in my messenger bag (which typically stays in my car) and the tech pouch that I use for travel. If I’m away from the car (on a hiking trail or in a theme park, for example), I still have the 2500 mAh one in my pocket if my phone needs an emergency charge.I knew when I bought it that 2500 was not enough for a full charge, but I figured that a decent partial charge would be good enough for short-term emergency use. I tested it by letting the phone’s battery decline to about 15%, and then connecting it to the TNTOR, which brought it back up to 70%. I think that’s an excellent result for a power bank so slim and light that I can carry it in my pocket without even noticing that it’s there.I see that TNTOR has a newer version, which boosts the capacity to 3500 mAh. But it also increases the thickness from 4 mm to 5.5. (Both models weigh 2.35 ounces, or 67 grams.) I wanted the thinnest power bank available, so I think I’ll stick with what I have.
Great Quality Power Bank for Peace of Mind. Excellent, excellent product. I will Never travel without it again. Easily fits in your purse or in a decent size wallet. Can charge your phone from 0 to about 2/3 (I tested it). Attached cable is a lifesaver. Also, it holds its charge until you need it. One emergency, one time your phone battery runs out of power when you need it most, and this product will pay for itself MANY times over. In addition, it is solidly quality constructed from lightweight metal. It also holds its charge well, as I’ve had it in my picket for a couple of weeks now and it’s still at 100%. This company also has a newer one with more power that is only slightly larger. I will also buy that one when I have saved up enough money and I will write another review there after I buy that one. BUY one of theses, you will be SO happy you did!!!
HAS TO BE THE SMALLEST POWER BANK OUT THERE-ONLY WISH IT WAS USB-C INPUT. This is about the thickness of two credit cards. I got the one with the Apple lightning built in cable. If I need to charge my iPhone I plug it in and use a rubber band to hold it on the back of the phone so I can keep using it. The power cord is fixed to the unit and is kind of thin so I’m careful with it. I do wish it had a USB C jack for charging instead of Micro USB as USB C is newer, faster, and can be inserted easier. But overall happy with it.
Good For Emergencies. Recently found myself in a jam with a dead cell phone battery and no cable for a recharge. Definitely an issue when away from home. No UBER no digital pay, minimal cash and lot’s of problems. Found this item and gave it a try.Pros1. Very small and lightweight. Slightly larger than a standard credit card and thick as 4 stacked.2. Built in lightning cable clips into it’s own recessed slot.3. It took my old IPhone 8 which has an 1800 mah battery from 10% to 75% in about an hour.4. Metal outer casing gives it some toughness against puncture and cracking.5. Been carrying mine for 2 weeks and it is still at a full charge.Cons1. Did not fit into a standard credit card slot but did fit into the larger interior pocket as well as all of my EDC pouch style wallets easily.2. Lightning port plug feels pretty fragile. Definitely needs to be treated lightly.3. Slow to charge.Overall for the price the one I received seems like it will be a solid emergency power source.The smallest version which is the one I bought isn’t going to give a full 100 % charge from a 0% dead battery but it will give you more than enough to get out of trouble and given it’s size and weight it’s an easy daily carry.
Fits anywhere. 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 power bank. The media could not be loaded. Super small size, thin, but holds enough charge to get your phone back on its feet. It’s not going to do multiple charges but as an emergency backup for a night out it’s perfect. You can out it in a pocket or any club purse. The included cord seems fragile but it’s incredibly convenient—just hoping it won’t break off!

FINALLY a very slim charger that fits easily anywhere, 4 1/2 stars because won’t fully charge S24+. FINALLY an easy carry charger that fits easily anywhere without noticing, fast charge. It is the thickness of two credit cards. Can fit in a bigger wallet, front pocket without noticing it, extra in your car or purse. It is fast charging & charges fast. I would actually give it a 4 1/4 stars because it won’t fully charge my new Galaxy S24+ phone, but that thing has a huge battery. For an emergency back-up, 80% is all I need.

works, very small and lightweight, appears to have an aluminum shell. This does, in fact, charge my Galaxy A52 like it’s supposed to! Only maybe half a charge, but it’s a very small battery so that’s what’s to be expected. Exactly what I’d hoped it’d be.
I don’t always carry a portable device but now I do. This is a good charger for emergencies only and when you don’t have a charger around. It charges a decent 30%-40% for my phone before recharging it. It fits perfectly on my wallet (double sided tape to keep it in place) and blends with it. Now I carry a portable charger 24/7 since it’s so small and slim. I don’t give it full 5 stars because I wish I wouldn’t have to recharge it that frequent and wish it would charge my phone a 100%.
