Maymom Breastpump Power Bank Kit for Medela Spectra breastpump. Battery charger

Description

IMPORTANT! Cells (18650 flat top Lithium batteries) and a USB charging power source rated 2A and above are required for this Power Bank but not included in this listing. Buy batteries first. These rechargeable batteries normally last more than 500 recharge cycles. Two lithium batteries can provide up to 2.5 hr continuous pumping, while 4 batteries can do up to 5 hr after each recharge. NOTE: Some 18650 cells have a total length much longer than “65 mm”. They will not fit this power bank kit. Please buy the flat top ones.
IMPORTANT!! Lithium batteries must be installed correctly to prevent metal burning smell (due to coil overheat). Read instructions very carefully before installing batteries.
