Title: Power banks
Post by: T.O.M. on March 19, 2018, 09:23:24 AM
No, I'm not talking about the big money banks, I'm talking about the portable devices you can use to charge electronic devices, like cell phones.  We've bought a few of the ones you see at Target and other places for $15-$25 per battery, and it seems like they either won't charge a phone more than half a charge, or the darned things last only a few months of diminishing performance before they don't work at all.  Last one I picked up in a bargain bin at the grocery store wasn't worth the $5 I paid for it, as it only put about 15% onto my phone.  Anyone have a good power bank they can recommend?  Primarily use it for my Samsung Galaxy S7 phone, my iPod, and occasionally my Samsung tablet.

I've been using an Inland charger, like this one, for a few months.

It has no problem charging my phone, although I can't speak to its endurance. I've only used it a handful of times.

The battery capacity of the S7 is 3000mAh.  I would get a charger that is at least 3X of that if you want any use out of it.  I bought a couple of different  brands (20000mAh) on Amazon over the past 3yrs.  Each was around $25 with free shipping. Both still work well.  Of course neither are still available. This one looks decent and gets good reviews.  It is the size of another phone though.  https://www.amazon.com/EasyAcc-20000mAh-Portable-Recharge-Capacity/dp/B01422TC14/ref=pd_sim_107_3?_encoding=UTF8&pd_rd_i=B01422TC14&pd_rd_r=PZ769WBQQ7BFED5N6JEQ&pd_rd_w=ooMQu&pd_rd_wg=VymN4&psc=1&refRID=PZ769WBQQ7BFED5N6JEQ (https://www.amazon.com/EasyAcc-20000mAh-Portable-Recharge-Capacity/dp/B01422TC14/ref=pd_sim_107_3?_encoding=UTF8&pd_rd_i=B01422TC14&pd_rd_r=PZ769WBQQ7BFED5N6JEQ&pd_rd_w=ooMQu&pd_rd_wg=VymN4&psc=1&refRID=PZ769WBQQ7BFED5N6JEQ)

I've got an 10Ah Anker that's about 3-4 years old, I still get multiple full charges off it.

Anker

My wife bought me an Anker brand power bank a few years back for Christmas.  The thing works like a champ.  It charges my S4 without a problem, and usually has about 25% charge leftover.
I picked it up off the desk the other day after it sat unused for a couple of months, and the charge indicator still indicated 100%.  The self-discharge rate must be pretty low.

I have a smaller Anker that I bought maybe 5 or 6 years ago.

It sat unused in a desk drawer for the better part of 18 months. I pulled it out a few weeks ago and it still had 75% charge.

Anker  Power Core 20100 ordered from Amazon for $41.  See how long I can keep it before my wife takes it as her own.

I have an anker unit that chargeomy phone about 4 times. It's about the size of a pack of cigarettes.  So far so good. I do wish that I could charge the pack while also charging my phone, but it doesn't allow that.
