Recommendations for cellphone power bank ?

There are a ton of choices on Amazon. Cost, capacity, size, weight, built in cables, # of ports etc. What ever is most important to you. My husband wants one that has lots of capacity and doesn't care about weight. I prefer something lighter with built in cables so I can carry it in my purse while charging.

Also, I assume your Samsung has a fast charge plug as mine does - it won't be useable with the power pack so charging will be slower.

I have a phone case with an extra battery. It holds 150% extra charging capacity. I like it because it doesn't require me to carry an extra item. I have an iPhone, but I'm sure they must make them for Samsung's.

Anything made by Anker, they're a very reputable brand.

Take a look at wirecutter , a sort of consumer reports site , part of The NY Times https://thewirecutter.com/reviews/best-usb-c-battery-packs-and-power-banks/

I have a small Duracell charger that I got for less than $10 at Office Depot.

I have had good luck with Mophie chargers. It’s the size of my 6s iPhone. But it’s heavier than some and costs a little more. I have 2, both bought from Best Buy. One has 2 charging ports, the older one has one.

I'll second the recommendation of Anker brand. I've had one for several years and it works great.

3rd vote for Anker.

One other feature to consider is whether the power bank will support quick charge. My new plug-in iPhone charger has that capability and it works well. Each of the power banks on the above website has a "pros & cons" list to summarize the features.

There's a definite link between weight and storage capacity. I, too, am happy with my Anker device, but I wish it weighed less.

Add me to the list of those that recommed Anker.

Thanks to all for your input. I'm trying to balance power vs portability -- light enough to carry along all the time but with enough power to make it worthwhile carrying. Research continues.

Anker for the 5th? Time

I have a small plastic charger case that just holds 2 AA batteries and has a USB connection. The case is very lightweight. I can bring one set of batteries and buy more if I need them. Great for earthquakes, too. Though for that, I'd really like to get a solar charger.

I have a bunch of these but keep looking for smaller and more powerful. I switch back and forth between these two:

Powerful, quick charging and I like that it gives the percentage of a charge left rather than just lights.

This one is so superlight and thin. Great for a pocket.

Both have worked well.

Another Anker vote here.

Thanks, all! I ended up with an Anker 13000 bought online from Wish for about $30 (two other electronic purchases from Wish came inoperable but refund was immediate.)
