So . . . I have too many power banks.  I had 5 already and then I got the Momox power bank with wireless charging with the Note 10+ pre-order deal, bringing it up to 6.

Now PBTech go and offer this: https://www.pbtech.co.nz/product/BAPMIX22234/Xiaomi-Mi-20000mAh-Power-Bank-3-Pro-Edition---Blac

So now I'll have 7 power banks.  Anyone want to buy a couple of older power banks that only charge ~10W?  I only use my QC3.0 or PD power banks normally anyway.  I recently went on a motorcycle trip, camping each night and by the time I got home I'd spent 23 nights without sleeping indoors.  My motorbike has 2 QC3.0 USB sockets, I put one or two power banks in the tank bag with USB leads going to those USB sockets, this lets me charge my power banks as I ride.  I use the power banks to charge my Tab S4 10.5" tablet, Note 10+, camera, action camera, bluetooth comms on helmet, Bose QC35 II headphones, flashlight, etc.  I really do find the power banks useful, but on the last couple of trips I only used 4 power banks, the ones that charge the quickest.  None of my current ones have 45W in & 45W out though - that is a big step up.  I wonder how quick that power bank would charge from a 45W charger compared to my 25W charger that came with my Note 10+, possibly not worth the cost depending on the difference for the charge time.

My first power bank is a Xiaomi 16,000mAh power bank with 5V 2A charging (each way) which takes WAY too long to charge if it has been drained, like 10 hours or so.  My next least used power bank (Chuwi brand) has QC3.0 (each way) and can charge a device at 18W, it has 10,000mAh and works pretty well, until you need to charge it - it only charges at ~12W because it only goes with ~7V and under 2A.  My Xiaomi 10,000mAh power banks (I have 2 of those) charge at ~19W by going with ~9V and ~2A with a little above on each value to actually exceed the QC2 or QC3 specs.  The Momox charges at around 18W, pretty much sticking with QC3 or PD specs.  I'll check the new power bank to see what the actual charge rate is.  I also have a Xiaomi 20,000mAh older model power bank that is 18W each way, so I'll have 1 x 16,000mAh, 4 x 10,000mAh and 2 x 20,000mAh power banks.

The new power bank should be my fastest charger for my Note 10+ since I don't have the 45W charger.  Mostly I'm charging at 15W wireless and that seems reasonably fast anyway.  I might want to get my phone charged fairly quickly sometimes, but I'm mainly bought this new power bank for the ability to charge the power bank much faster, rather than to charge the phone faster.
