BlueBuilt Power Bank with Fast Charging 20,000mAh

Bought to replace an older 20Ah power bank. Charging time from 18 hours with the old power bank to 5 hours with this new power bank. What a difference! It can charge a laptop with PD (Microsoft Surface Laptop Go (Gen1)), only when it is turned off, only with port C2 (output only). iPad, iPhone, earbuds, headset charge fine and quite quickly. What can you expect from this power bank? A comparison, the Apple power adapter USB C PD of 20W has the same specifications as this power bank when it comes to power. The specifications indicate that the output for USB is C1 and C2, PD 5V, 3A / 9V 2.2A / 12V / 1.67A. Although it wants to charge a Microsoft Surface Laptop Go (Gen 1) while it is on, this power bank cannot do this, regardless of the same output specifications. This power bank has 3 ports to charge your devices. 2x USB C with 20W per port and 1x USB A with a maximum of 18W. Please note that the maximum power is 20W, distributed over all ports. It is best to use 1 port for fast charging. It seems that this power bank can charge via a power adapter as well as charge a device (Passthrough charging), but this ensures that the output of this power bank may go to 10W or 5W. This way you can charge your power bank and your device at the same time.

The motherboard in the power bank shifts, blocking cable entries

The previous model broke right away. Gate was loosening internally causing constant loading stop. Thanks to Coolblue's fantastic warranty, a new device immediately and this one is fine. Very satisfied with it.
