Bolse multi-port USB wall and car chargers.
The Bolse 25W 5A 3-Port USB Car Charger retails for US$14.99 on Amazon. I'd expected three USB ports, but it actually has two ports plus an attached Micro USB cable. The 'three' means you can charge three devices at once.
The second Bolse product I got is the 40W 5-Port USB Wall/Desktop Charger, retailing for US$22.99 on Amazon. It outputs up to 40W and 8A across five ports, weighing 222g. It's a different design from the Bolse 25W 4-Port.
When Bolse emailed asking me to feature their products, I was skeptical, having never heard of them. A quick search revealed solid Amazon ratings and reasonable prices. The first product I received was this 25W 4-Port USB Charger.
