Let me guess, you purchased power strip B at
McLowesDepotBigBoxMartWarehouseSuperstore?

If you want a power strip with high-quality receptacles, consider a
Tripp Lite Isobar.

Probably even worse than that. A power strip in the U.S. lasts many
years. Here, the typical life time of a power strip is no more than one
year.

But that still doesn't answer why the same charger on the same power
strip can charge one phone but not the other phone of the same brand but
different model.
