INIU Portable Charger 5000mAh Power Bank for Apple Watch 20W PD Fast Charging with Built-in USB C Cable

I grabbed this charger when it went on sale and figured it would be a good backup to keep in my bag. I don’t use it with a watch, but it works great for my phone. It charges fast and gives me a solid boost when I need it, especially at the end of the day when my phone is running low. For its size, it delivers impressive performance. It’s small enough to fit in a pocket or clip to a bag, and it feels well made. The built-in USB-C cable is convenient and eliminates the need to carry extra cords. It’s perfect for travel or quick charging on the go. As others have mentioned, the capacity is limited since it’s only 5000mAh. You’ll get about 50 percent of a full phone charge, maybe a little more depending on your device. It’s not meant to replace a full-size power bank, but it’s excellent for those times when you just need a quick recharge to get through the rest of your day. Overall, I’m glad I picked this up on sale. It’s a compact, fast-charging little backup that’s perfect for short trips or emergencies. I wouldn’t pay full price, but for the sale price, it’s absolutely worth having Read more

I bought this to throw in my bag to top off phones and run a raspberry pi zero 2 tablet. It is not the lightest, smallest, cheapest, or most powerful option in the listed $30 range, but a nice balance in the $20 range (on sale). You will need an adapter kit with this or your own cable if you have a lightning phone. For comparison, the Anker 10k Zolos are around $20, sometimes go on sale, but are physically bigger, about twice as wide and a third again longer, with the same thickness. They are twice as powerful, and 30w, so my kids borrow them all the time to charge up their iPads. If you're okay with a bigger size and need ports and passthrough that's the one I recommend. It meets the Pi's needs as perfectly as if it were made for it, it's just heavier than I want to carry around in my purse for "just in case" moments. Also, if you need to charge your phone routinely, you'll be better off with an Anker or similar that snaps to the back of the phone. Everything works as expected, though it is not a UPS and the power cuts out when you unplug it or plug it in, obviously that feature would cost a whole lot more. Over about an hour plugged in and running my device, it's gained about 10% charge and is cool to the touch. No complaints. Read more
