I can also now confirm that my 45watt USB-C wall charger will only charge this to 86%, but my Macbook Charger that is 87watts is good enough to get it to 100%.
I have no clue how many people seriously claim to be experts here and just present opinion as fact over and over.
Personally, I've tried to avoid LiPoly for going on close to 20 years.
They have way too many downsides compared to Lithium Ion, starting with the fact that they are even less shelf stable.
It also doesn't sit well with me that they're incorrectly telling people to "calibrate" the battery by fully depleting it.
Remember, people: Lithium based batteries do not have a memory effect and thus can't be calibrated through power cycles.
All you're doing by depleting it fully is stressing the battery, which actually causes it to not hold a charge as well.
It's common for batteries in a pack to have different states of charge (e.g. 4.05v, 4.12v etc). In those situations it's common to rebalance individual cells to bring the voltages in sync either by top balancing or bottom balancing cells.
A lot of Battery Management Systems have an automatic rebalancing algorithm that will do a bottom balance when you discharge the pack below 10%. Because this pack has discharge protection, 0% on it's gauge is likely just the threshold where it cuts off but isn't truly depleted. And discharging to 0% would trigger the bottom rebalancing.
It's also possible this is cheap Chinese crap and will burn your house down.

Amazon says this is a frequently returned item and as multiple users reviews point out the short coming comes from using standard powered USB chargers.
Use a 65watt charger and this thing is insane for how much battery you get per dollar.
The fastest charger I have is a 40 watt. Do you think that is better for it shorting it while charging it?
As my previous update stated... A 45watt charger only got it to 86%. I had to use an 87watt Apple MacBook charger to get it to 100%

And rightfully so because mAh is not a definitive metric. You could have 60,000mAh based on 1.2v pack/cells and the wh would be only 72. Not every individual battery is 3.7v.
Not saying you don't know this... Just quoting to make a reply for others to see why mAh is a BS metric and to always look for wh.

These aren't usually bare cells. They have charge controllers.
This is a multi-cell configuration.
Evatronic, sister brand is Alfox. They seem interchangeable as far as brand names. Both of those are new brands for the RAV power brand that was huge on Amazon for so long but got kicked off Amazon for trying to influence reviews or something a few years back. Back when brands would include little things saying give a five star review and we will give you a $5 coupon or something. Amazon did a big purge. These are the new brands to get around the block I suppose. Can find all of them on Rav powers web site so all the same company.
I had great success with the brand back then and this new power bank does not disappoint so far anyway. I got one that would do 65w charging so I can do full fast charging on two phones at once, or use for laptop as needed. Works great in testing for both use cases.

I'm not calling anyone a liar, and certainly am not one myself. This was my experience; take it or leave it as you choose.
I'm very happy with the two 40,000 units I bought. I'm currently discharging the second one to 0% for initial charging.
