Miady 2-Pack 5000mAh Mini Portable Charger, 5V 2.4A USB-C Output Fast Charging Power Bank for Travel Small Battery Pack Compatible with iPhone 16/15 Galaxy S24/S22 iPad Android Smartphones etc

I own exactly two usb powered "heating" items a large blanket and a neck scarf. The scarf has a small zippered pocket for the battery so it will not fit a full size high capacity battery pack which is ok because you probably don't want all that weight hanging around your neck anyhow. These have a USB A plug and a USB C plug. The C plug functions to charge the battery or as output as well. Most usb heated clothing items are still using a full size USB A plug for their power input. These have light up LEDs on top so you can see how much charge it has and there's a power switch next to the plugs. It's a few hours to get them to full charge using a USB C cable (2 included in the box). These are 2.4A output plenty for small items like a scarf but the larger blankets or shawls generally want a 3A capable power brick to be used (most likely because of the greater resistance in the circuit). Phones generally recommend 2A output for chargers so this should charge any phone. These are great but I would have preferred a micro usb plug like my other power banks have since I still have a couple of devices that use that old plug (adapters are available so not a big deal). These are a good price for the size and will do what I wanted them for, to keep power on my heated scarf for my sore neck.

Miady 2-Pack 5000 mAh Mini Portable Charger.I have been using the older 5000 mAh version of the Miady block style chargers for about 4 years. They still work, I just needed some with a USB-C port. What I like the most, is that this manufacturer is honest about the battery capacity. Some other manufacturers make wild claims about capacity, Miady does not. Most all battery powered USB chargers run at, or better than, 80% efficiency. The losses are due to power consumed in voltage and current regulation circuits. I tested these and got a little better than 4000 mAh on the business end, which is very good. I use these mainly for powering USB devices like portable fans or lights, sometimes for charging my portable razor and hair trimmer. These do work on phones but you may want to look into some of the 10000+ mAh versions for better capacity and charge speeds (hint, PD is fastest for newer smart devices).

I got these for their compact form factor and they are nice and small while still providing 5000 mah of charging. They're about the size of a deck of cards and would be great to keep in a car or bag as a backup charger. I like that there are 2 different colors to differentiate each one.A couple of criticisms, the plastic housing quality could definitely use some improvement. It's very barebones and not bad but could be sturdier and smoother. The USB type A connection also juts out slightly when something is plugged in and I would prefer that it went all the way in. I suspect this is all related to the small form factor.

These little chargers are amazing! I can charge my phone with them! They come in very handy when the battery is low on my cell phone! And they are perfect for connecting to my heated jacket! They charge quickly, they are very well made! Charging doesn’t take that long. Don’t hesitate to purchase them!

These are awesome compact chargers. I keep one in my purse to charge my phone whenever it’s getting low. I pack these for vacations one for me and one for my husband and we both love to have them with us.

Much lighter than the larger ones I bought, but with the same capacity. I haven’t really tried it out yet, but I love the size!

Warning! Puffs up like a balloon, AKA that sign that you're about to get a 2500° fireworks sparkler instead even if you ordered a battery bank. For best results I'd wait till charging on the 4th of July and invite the kids over!By the way this was done completely under reasonable conditions inside using regular USB chargers so like watch out if you keep this in your backpack or fly on a plane with this.Worst thing is now I have to find a place to pay to dispose of this product that is now an environmental hazard. Thanks Miady, I know I can only count on you for a pain in the butt! Last last time I had to drive over an hour round trip and back and pay to dispose of it so unless you want to like spend money to spend money to not have a working product, I'd buy something else!By the way, I have four of these and two of them have expanded. Maybe these were destined for Hamas but I got them instead.

These are a great deal but there’s some real drawbacks, at least in my experience. I get far less than a full iPhone charge with these which doesn’t seem right. They also don’t hold a charge much at all. If you don’t use them in a day or two after charging them, they’re probably drained. That’s kind of a tough sell when a big reason to own charge packs in general is to have them available whenever you need them.I’m oddly obsessed with having battery packs available everywhere around the house at all times, so I can figure out use cases for these but the options are pretty narrow.
