I own a few of these Morphies and my family has been pretty happy with them. There hasn’t been any complaints about them yet and they get a lot of use. Do note the USB-C. Since there are models with the old USB-B on it still.
The only ones that were more reliable were the old sneaker covered batteries. I still have those and they surprisingly work.

@digitalblunder@RedOak The price of lithium batteries in terms of dollars per watt-hour has been dropping by slightly over a factor of ten each decade. If you didn’t check the price within the last month, it is out of date.
At one point, Panasonic’s highest capacity 18650 could hold more than 3 times the watt hours of their highest power cell, while the highest power cell could safely handle more than ten times the amperage.
Cell designers make a whole lot of tradeoffs depending on the target market. They optimize for one or a few specifications at the expense of the others: rated capacity, maximum discharge current, maximum charge rate, weight, guaranteed number of cycles, and cost are interdependent variables.
I have seen some LiPo batteries that were rated for only 25 charge-discharge cycles. They were optimized for inexpensive toy drones. The drones are sold with 2 or 3 batteries, so the rest are charging while one is flying.
There are a bunch of manufacturers that make batteries that are significantly cheaper than the Panasonic cells, but many of the specs aren’t as good. There are companies that still make and sell 1 amp-hour 18650s.
In for one (pair.) I have the smaller pink Mophie cell phone charger and I am pleased with performance. It keeps my Pixel 2XL going when playing Pokemon Go outside in a Chicago winter. The only quirk is that it won’t charge plugged into the USB-C port on my laptop. Cell phone does fast charging that way. The Mophie will slow charge plugged into an ordinary charger using USB A-C cable and that’s my preference anyway. Slower charging should extend cell lifetime.
I don’t recommend these. I originally ordered 2 of them and one of them wouldn’t charge. The lights flashed and it appeared to start charging, but never got any higher than 1 light after an overnight charge.
After getting a replacement set from the most excellent Katie in customer support, the same issue has happened again. This time I reached out to Mophie support and the best they did was offer a 10% coupon. I told them that I already lost confidence in their product, their response was that purchasing through their website gives the 2 year warranty.
That’s not reassuring. If you want me to crap in a box and slap a guarantee on it, I can do it (I have spare time), but all that means is I have a guaranteed piece of crap.
