Great products!
They all worked and I was able to make a portable battery charger that was able to double as an anything 5v off of USB port travel charger. I even added a solar panel to charge the internal battery outside! Everything works great!

Inefficient device charging
Charging board works to charge the battery pack, but the output power board does not deliver enough current to fast charge devices. Very inefficient and as another reviewer noted it does drain the pack quite fast. I have 4 18650 batteries hooked up and it will not fully charge a Samsung Galaxy S9. Brand name charging packs of similar capacity will charge my phone twice.

What are you making?
Easy to set up, but has limited potential and drains your batteries fast
