Looking for opinions about these 2 - 5 volt usb solar regulators circuits...

So I've done a basic 5 volt voltage regulator and heat sink for a small usb charger off of a 6 volt nominal panel. it's simple and works flawlessly but I haven't used it much...
I recently saw a couple different voltage regulator circuits on eBay and figured I'd pick them both up and play with them.
Wonder if anyone can point out glaring superiority of one over the other as I have a bunch of solar shingles recently pulled that are 60 watt 6 volt nominal.

Regulator 1

Regulator 2
Both come in small plastic housing, Obviously one has caps and one doesn't...
I was thinking about making some small solar battery bank chargers, and maybe group them with an inexpensive 10,000mAh power bank,
These $10 units appear to be legit;

A usb Fan and light. I think I might convert a couple small 5" O2cool fans, or maybe pop for some better Opolar 8" fans. And a long USB extension power cord, which I might have to make with heavy enough wire so that they can charge a phone inside and run a fan while charging the bank. This begs another question, can These handle having so much available power (7 amps). One of them says 2 amps input, I figured they would take what they needed?
Also would running 2 of these at the same time off of 1 panel be a problem?

Hi ..whit,
Regulator 1, also has caps, they are just some Surface Mount types -- C1 - C8, on the legend.
Reg 1, might be a bit better, only for the use of those caps, verses the Radial Lead type, used in Reg 2 ... this is based on NO real info.
Nice project, good luck, Vic
For a gift to family I would only use LFP for safest operation. They also can be damaged from charging too fast.
Good Luck!
