The suitability of Tellur's "Graphene PD10000 Power Bank 10000mAh" for recharging HP computers and mobile phones depends on a number of factors:

1. Compatibility with HP computers:
- To charge an HP computer, the power bank must support Power Delivery (PD) and have a sufficiently powerful output. The Tellur GPD100 power bank supports PD 3.0 with a maximum output of 18W via USB-C, which is generally insufficient to charge most HP laptops, which often require outputs of 45W or more.
- As a result, this power bank is unlikely to be compatible for charging an HP laptop.

2. Compatibility with mobile phones:
- The Tellur GPD100 power bank is compatible with mobile phones, as it supports Quick Charge 3.0 and Power Delivery, allowing compatible devices to be charged quickly.
- It can therefore be used to charge a mobile phone without any problem.

In short, this power bank is compatible for recharging a mobile phone, but probably not sufficient for recharging an HP computer.
