Today is my second day to use the adapter to pump during my lunch break at work. It is working with my Hygiea EnJoye double electric pump.It seems to be providing adequate power, but I do have to turn up the settings on the pump on both speed and strength... compared to being plugged into the regular cord at home.The cord I received does not look like the adapter pictured (which was the same photo on the Hygeia website, and the reason I purchased from this seller). My cord looks much shorter than shown in the photo and the plug looks much different. As you can see in the photo, the pump needs to be pretty close to the outlet. Someone mentioned in their review that the cord was long enough to use in a rear outlet, but that is NOT the case with the cord I received.I have to pump in my car a couple times a day at work and was hoping to pump during my 30 minute commute as well. However, there is a sticker wrapped around the cord that says: "WARNING: USE OF THIS ADAPTER WHILE DRIVING WILL VOID YOUR PUMP WARRANTY." This was not mentioned in the Amazon description, and is not listed on the original Hygiea website in the specifications. I am wondering if it will damage my pump... it also makes me think that the adapter I received is not from Hygiea as advertised. I really wanted to be able to pump and drive. :(I will update if needed, seems to be working so far.The charger worked great daily for four months. Then one morning nothing. I looked at it and the wires were exposed at the plug. I always pulled it out by the charger not the cord. Disappointed this did not last longer.For the few times I have had to use this it has proven reliable. I'm going to be needing it pretty much daily for work starting in a few weeks. Hopefully it keeps up. The cord does appear very short but worked fine. I use it sitting in the back of my Edge using the outlet in the back as well.Works great but the cord is VERY short - much shorter than it looks in the photo. The spiral part is maybe 5 inches long.Great to have as a back up.This worked very well for about 6 weeks, then had to be twisted to get it to sync to the machine and then stopped working altogether. I have no problems getting my pump to plug in at home so I know it isn't the pump. Instead of buying another I got an adapter to be able to plug the wall plug in the car, what people buy to charge their laptops on the road. Costs about the same and now I can plug anything in I'd like.I bought this 7months ago when I returned to work. I do not always have access to the Break Room at work, so I needed to be able to pump in my car. This did the trick and works perfectly for my Hygeia!I didn't see it listed, but this does in fact work for the Hygeia Enriche in case anyone is wondering!Everyone should have one of these. This car adapter makes pumping on the go so much easier. My husband and I just travelled from Florida to Pennsylvania (1300 miles), and having this adapter made things go so much smoother than I anticipated. Great for road trips or getting an extra pumping session in on the go.
