A well-made fast charging power bank should be robust and not only useful when travelling. The Recci RPB-W27 has a foldable full-width metal foot making it perfect on my desk to hold my phone while working.

I am not able to buy another unit of this power bank anywhere, so you might have to buy the more expensive Ridge Power Bank. I have not personally tried it out, but the differences from the Recci seem acceptable—the cables running down the sides might even give more space for the devices you charge. The foldable foot might be unstable, and seem to also allow placing the unit in landscape orientation. No idea why you would want that though, as it is less practical.

The Recci comes in Obsidian black and Titanium color, both look great. The Ridge comes in Basecamp orange, matte black, matte olive, and atomic purple (transparent).
