YouTube has several videos featuring really bad designs for fast phone chargers. YouTubers doing these videos often point to problems such as transformers with chintzy insulation, line capacitors that lack the correct safety rating, and even chargers with plastic cases that heat up so much that they actually melt when there’s a heavy load. Fortunately, […]
