The INIU 20000mah 45W power bank was a Slickdeal for $19 a couple of months ago. I think that is a much better deal that I would wait for if you don't need this slow speed (22.5W) version right now.

Indeed, that was a much better deal. These higher capacity power banks at lower wattage output kinda suck.

OP should clarify. This does not have a built in cable. Those have one end free and the other hard wired. Those should be avoided at all costs because the cable will get snagged and pull loose the connections inside.

I bought one of each from this brand. I got rid of the one when the cable got pulled out. I still have and love the other.

However, I agree that I'm willing to wait for a higher wattage unit at 20k mAh

I bought 5 days ago the 25000mAh 100W one that looks the same. In the manual it states that it has 15500mAh usable capacity. I have a 3-4 year old S23 ultra with an advertised capacity of 5000 so who knows what's left of it. I tracked how much the power bank charged the phone from 100% to 2% of the pack, and that 290%. In other words, assuming that my my 4 year old phone has 90% of its battery capacity left or 4500, I got 2.9x4500=13050mAh which is 52% of advertised capacity.

I was not expecting 100% , but not 50% either. By comparison, by 10 year old Anker 20000mAh can still charge the same phone 230% which is 51.7% of original capacity.

So a 10 year old 20k Anker has the same charging capacity (percentage wise) as this brand new unit. I am sending it back, but wanted to share.

Just so every one is aware that this does not have a built-in USB-C cable, the so called built-on cable is the detachable handle.

I own both this one and the 45W one.

Small USB cable acts as lanyard in these.. Convenient to carry - I have previous version on these.

How does anyone feel about the Baseus 20000mAh Compact Portable Charger 45W, CCC Certified Power Bank. How does it compare to the INUI 45W. Is Baseue better than the Inui? The Baseus was on SD last week for $23. Thought?
