I have Lenovo Thinkpad Edge S430; it's an old laptop (2012 model) but I like it as it has two hard drives (1 x 128GB SSD and 1 x 1TB hdd), Intel i7 and 16GB memory inside.
What drives me mad is the battery capacity; I managed to replace the internal battery a couple of years ago; but now it is started to drain too quickly (15 minutes without power adapter).
Rather than purchasing another internal battery, I've been thinking to buy a powerbank.
I contacted Lenovo, unfortunately, they don't sell powerbank for laptops; does anyone know what are my options here?
I saw Dell has powerbank for its XPS laptop; that is really a neat thing (no long-winded cords and extra juice when on the plane)
Note: the adapter states: 90W 20V
