Game changer
This is a game changer for exclusive pumpers! Wish I found this sooner. Lasts for about three 30 minute pumps. Going to buy more to have on hand.
Great accessory!
Game changer! Battery works well and lasts for 2 or 3 pumps before needing charged again. I love it because i can just grab the pump and move to another room easily, if baby is sleeping in the room i normally pump or if Shes playing in another room I can leave her there and bring the pump with me.
Pretty nice to have, slow to charge
This is a brilliant addition to a very underrated pump (itâs so quiet!) but the execution seems lacklustre. It lasts for around 4-5 pump sessions, so about 2.5-3 hours total for my settings. But the charging is so slow. I havenât looked to see what time it is rated to charge in but it has to be more than 12 hours.When itâs plugged into the running pump and plugged into the wall, thereâs a squealing noise that comes from the battery pack thatâs very alarming. I have to use the cord plugged straight into the wall when pumping.
Game changer
I wish the pump just came with a battery pack. The ability to move it anywhere without needing a wall plug is a game changer when you consider how often you will be pumping.
Garbage ! Never worked
Just tried this for the first time since purchasing it is junk. Charged it up and it will not even turn my pump on! Very disappointing considering I was in the car and needed to pump and expected my battery backup to work ð¡
Works
Seems to last a decent length of time i unplug inbetween usesOnly downside is doesn’t have itâs own carger cord
So far okay
It gives a humming sound while using when on charging.. so far works good.. purchased a week before
This is awesome! What a great feature for this pump
I do not regret buying this battery. It last approximately 3 full cycles of pumping and it’s the same full force. It recharges pretty fast too. I love it because it gives me my freedom back. It fits perfectly well with the dr brown pump. On another note, it does not work well with other pumps.
This is well worth the money to be a bit more mobile while pumping. Just watch the battery life so it doesnât die mid-pump.
Makes the pump portable. Battery lasts about 4 pump sessions before needing to be recharged. Very happy with this purchase.
Bought this very recently. Charged/used it once. Worked well, once. Upon second charge, Iâm not sure what happened, but my dr brown plug in pump is no longer functional. It turns on but has 1/100th of the suction power. The battery no longer charges now.So frustrating. I really liked the Dr brown pump and are out a 100$ product that we canât return.Do not buy!
