Exactly correct. It's a phosphate-based battery, so it's essentially useless for a phone or laptop. Great power density, REALLY crappy energy density. Not only do phosphate power cells have much lower Ah ratings, but their average voltage is lower too (3.2 nominal vs. 3.6 nominal). The end result is the energy density of phosphate based cells is roughly HALF that of NMC based cells. So yes, you could charge your phone in 10 minutes, but you'd need to because you'd be charging it more than once a day.
