I have got LENOVO notebook U41-70 IBD. I find the battery a bit short ... more or less 4hours. I would like to extend the battery length up to 7hours by adding a power bank. Need to know the built-in battery capacity ... (5000mAh ???)
Any suggestion for using such a powerbank ???

Good day and welcome to the community.
Looking at page 65 of the hardware manual: https://download.lenovo.com/consumer/mobiles_pub/lenovo_s41-35_s41-70_s41-75_u41-70_hmm_201503.pdf the 2- and 3-cell batteries (item #12) are 30 and 45Wh, respectively.
Hope this helps a bit.
