The electric bike I have has a 48v , 15.4ah battery.
The charger for the bike reads a 120v-240v ac input , with a 2a output.
The portable powerbank I am looking at is here, https://www.amazon.com/dp/B06Y3NF7N2/ref=sspa_dk_detail_0?psc=1&pd_rd_i=B06Y3NF7N2&pd_rd_wg=xjXEP&pd_rd_r=RPT4RMBVXEH370Z8P1AQ&pd_rd_w=vuzsq
42k mah capacity with 250w/110v output
Would this be sufficient in charging this battery?
Also if I were to keep the powerbank charging the battery in a bike mount , while the bike was in operation, would that cause any problems?
Below are pictures of the battery and the weight. It's a dinosaur.
That is 12lbs.
(I bought the bike from a previous owner who seems to have shorted the battery , because the bike does not seem to go as far as I would like it to , and the battery charges very fast , which lead me to the idea of a portable charger.)
