PULUZ Fast Charge Hub for Insta360 Ace/Ace Pro, Battery Charging Box & Memory Card Storage Case, Quick Portable 2 Channel Battery Charging Storage Station with Micro SD Card Storage Slots Accessories

This review is for, "PULUZ Fast Charge Hub for Insta360 X4 | Memory Card Storage Case for Action Camera, X4chargehub" It charges a pair of batteries simultaneously, works with lower power USB-A/C power brick, slow charging. Would have loved if it worked with higher powered USB-C prower and charges fast. Price, 17.89, is bit high for low powered charger. Design is great, there are slots to carry microSD cards. Works for me, though not fully satisfied, it does what it supposed to do, charge couple of batteries simultaneously.

Initially, I used my USB C charger with this case to charge my battery and was wondering why I was not seeing any indications that it was actually charging. I let it sit for a few hours and put the battery in the camera and found that it indeed had not charged. I then pulled out a USB A charger and as soon as I plugged it in, the LEDs that I did not know where there, lit up. Once the color of the LEDs turned green, I put the battery back into the camera and it was fully charged. I knocked off a couple of stars as the charger has a USB C port for power and should meet the USB C spec with the proper pull-down resistor to indicate that it requires 5V at 500mA. It does make me question the engineering quality of the charger.
