This power bank got my insulin from Los Angeles to Texas on a 3 day Amtrak trip in the middle of a hot summer safely. I used it with my Voyager insulin cooler/chiller. There was about an hour when the power cut off on the Amtrak, but the temperature held and I was able to see the temperatures from the usb lid throughout the trip. I kept it plugged in throughout the trip - via the cigarette lighter/charging in a car, plugged into the wall outlet on the train, and when not near an outlet the powerbank had plenty of power left. I was worried I might run out of power and lose several insulin pens. But this along with a Voyager was dependable. Now I am confident about future times it may be needed. Read more
this backup last a good 48 hours in use, the good thing about the holder it goes with is you can plug it in the car when you're traveling and charge the backup and then use the backup on the plane or train whatever you're traveling on and keep your pens cold. Read more
Great battery, easy to charge, easy to use. I just wish they lasted longer when powering the 4AllFamily cooler. When fully charged they will go for a few hours, but not long enough for a direct flight from US west coast to Europe. For flights over 7-8 hours, if the seatback USB ports don't work, you'll need two batteries for each 4AllFamily cooler you have. Read more
Product just as advertised. Powers the 4ALLFAMILY Voyager well and has always powered for just over 24 hours for me. Only issue is that once the power bank displays 50% it drains rapidly Read more
I was used this battery with my 4AllFamily Voyager XL cooler to keep medication cold for a twenty-hour flight sequence by charging this battery in the plane’s seat outlet WHILE THE BATTERY CONSTANTLY POWERS THE VOYAGER. We all know plane outlets are sometimes unreliable, so the battery keeps the meds cold while the power is out and during layovers, and recharges when charging is available again. The battery life is what’s advertised. Buy it! You won’t be disappointed! Read more
I purchased this to power my 4ALLFAMILY Explorer. It worked flawlessly and travels well. It is very easy to use and did not need to be recharged even though I used it for 8 to 10 hours a day for a week when the temperatures were in the mid to high 90s. For anyone who is thinking that it is just a power bank and you can use any power bank with the same specs to power the 4ALLFAMILY Explorer, you may want to consider what you would do if the other power bank fails or causes problems with the cooling cap. Failed refrigeration could lead to medication that cannot be used. For me, it was worth every penny to protect the medication I was carrying because replacing the meds would have been very difficult while on the road. Read more
I bought this after purchasing, and returning another (recommended) 20000mah battery, that was on sale. Even though there was a holiday discount, I didn't really want to spend this much BUT here's my advice: if you have the 4AllFamily Voyager Cooler, BUY THIS BATTERY! Other batteries, it appears, won't always provide the STEADY load you need to run the cooling unit. After a while, they'll shut down for a few minutes which, if you're transporting medicine, ain't a good thing. We charged this battery up and plugged it in for a cross-country trip. We knew that, once we were on the plane, we could just plug into the power there BUT, at the start of the flight, the power on plane was flickering in and out and kept the cooler plugged in this battery. THIS RAN STRAIGHT FOR 11 HOURS! The Voyager cooler kept the temperature as desired -- great unit, by the way -- and, when it was all said and done, there were still 3 out of 4 lights on the battery . . . incredible. You've spent the money on a insulin/medicine cooler that needs power? Buy this battery! Read more
Great battery pack that can work with many products like cell phones, tablets, refrigerated insulin carriers, etc. Read more
