TNTOR Portable Phone Charger with Built in Lightning Cable, Credit Card Size Extra Slim Power Bank for Pocket Wallet Compatible with iPhone 14/13/12/11/X/8 Series (Not for iPhone 15 16 Series)

I have now bought two of these, because I “lost” the first one to my son/DIL, who borrowed it, liked it, and never gave it back. That one I had had for a long time, and had never had any issues with it. So now I bought another.When I bought my first TNTOR, I was looking for three things in a power bank: First, I wanted it to be really thin, like a credit card, so it would fit in with my credit cards and money in the very-small-sized fanny/sling pack that I carry around with me at almost all times.Second, I wanted it to have a built-in USB-C cable, because I can’t count the number of times I’ve had a power bank with me, but not the right cable.My third thing was actually something I didn’t need – I didn’t need much power, since all I ever use this for is to top off my cell phone at the end of a particularly busy/long day. So I wanted to trade capacity for small size, and the TNTOR’s 2500mAh capacity was just enough. If I had wanted a power bank I could use to charge lots of devices all day long, this wouldn’t be it. But that wasn’t what I was looking for.And, of course, there was a fourth thing – I wanted it to not be super expensive, and it isn’t. And I was lucky enough to get the second one on sale.So obviously, I was happy enough with this to re-buy it when my first one “disappeared”, and so long as you don’t want/need a ton of capacity, I imagine you will be happy with it too.

In my tests, I got slightly more than a half charge on my iPhone 16 and I’ve had no issue with the power bank loosing its charge after carrying it in my purse for several weeks. For day-to-day use, and even for most vacation days, I don’t need a power bank that will charge my phone 3X or charge multiple phones. Normally, I just want a little assurance that I can power my phone if I need to. This fills that need.

Best compact charger for the minimalist and for those with little space in your pocket charges well and great price

So far so good, will update on the true capacity of the battery during my tests.Stats:~5.6w charging speed, from both the port and built in cable~2100mahCons:Charging speed is not the best, about the average of most random low budget usb c cables.Charges itself a bit slower than the output, ~1 watt less.Lower capacity than advertised, only got 2k-2.1k instead of 2.5k, and it will only charge my Insta360 x4 (2.5k battery) to 80%. But to be honest, I wasn’t expecting much anyway.Pros:The slimness of it makes it very flexible as far as where I can fit it.The light weight of it allows it to hang off the usb c without damaging the port.Conclusion:Low capacity and slow charging/discharging, but the tradeoff is the compact size you get. Useful for emergencies or to just passively charge small things.Is it useful for your phone? For emergencies or just passively charging for a bit of juice yes, but you might want the higher capacity 5000mah version. But I rely on other much higher capacity and faster portable chargers. I carry multiple of these just to charge my bike accessories instead of using one big bulky charger and long cables.Important to note:Most built in cables fail easily, though this one hasn’t yet.Most banks this cheap also have a port that doesn’t last long.

Held a charge pretty well. Rarely used. Lasted over a month.

My tablet indicated the battery was charging the device while the battery itself was continuing to lose power. So whether the "powerpack" was plugged in or not, my device continued to lose power.

This is thin and lightweight, and provides enough charge to keep my devices operating.

It’s okay. It doesn’t stay charged very long
