Power One Pocket charger for ACCU Plus Size p10, p13, p312 (Capacity - 2 Batteries)

I seldom write reviews, but after initially thinking that I'd return this item I've found it to be a great device. As made clear by the manufacturer, the life of battery charge will vary with hearing aids. Mine have bluetooth functionality and consume batteries faster than others. I go through 312 Zinc Air batteries every 3 days. The Power One 312 batteries don't make it through the day. If I insert new batteries in the morning (6 or 7am), they're done about 5pm. I thought that this was a non-starter for me after the first day and switched back to the zinc air. However, after a week and 6 batteries I decided to try making a change in my personal routine.Now, I insert fresh batteries in the morning. Some time after mid-day, I make it a habit to swap out the batteries, which is easy because this pocket charger goes everywhere with ease and recharges quickly. So, with one change to my daily routine I've gone 3 weeks and haven't used a single zinc air battery yet. Once or twice I forgot and the batteries ran out. Fortunately, these batteries discharge differently than zinc air and provide me with at least a half hour advance notice when I receive the first "low battery" warning in my hearing aids. This is very different than the one minute warning with my zinc air batteries. So when I get the warning on PowerOne batteries, I can easily make time to swap them out before losing power.I'm glad that I gave these a second chance! Highly recommended.

The instructions that came with this device are riduculous. Ich spreken deutsch but it’s asinine that it was easier to read the German instructions than what passed for English. Get with it guys, this is the US and most of us speak English.Follow up. These things are junk. In exactly the same use situations these batteries last 6-8 hours while chemical batteries last 6-7 DAYS. What a flipping rip off.Follow up. This thing, whatever it is, is pure junk. It won’t charge anything and now has a constantly flashing red light. Of course the mfg won’t respond to my inquiries. Do yourself a favor and don’t buy it.

My wife bought a set of Kirkland hearing aids a couple of years ago, and her set came with a charger. I just bought the latest set of Kirkland hearing aids and they do not come with one. I prefer to use rechargeable batteries, like she does. Before I bought my aids, I researched the web to see if anyone had a separate charger available for hearing aid batteries, and voila! The Power One Pocketcharger fits the bill. It is small enough for me to fit in a shirt pocket, and itself has a "slab"-type battery that will give up to six or so charges "in the field." It also comes with battery holders for three different sizes of batteries: #10, #13 and #312. I use the latter.It also comes with an a/c adapter that allows the unit itself to be charged. The adapter has a removable "wall wart" to allow charging by a USB port. I have two sets of rechargeable batteries. When I have one set in my hearing aids, the other is in the Pocketcharger. If I go out and am not sure what charge level is in the batteries in my aids, I have the second set in the Pocketcharger and at the ready to swap out.Is it inexpensive? No. Rechargeable batteries are about $26 a pair and the Pocketcharger is $96.90 at Varta, but to me was well worth it. Keeps the zinc air batteries out of the landfill (not that I would toss them, but if on a trip would have to keep them and take home for recycling).The unit also is a "smart" charger. It senses each battery's charge level and will quick-discharge them before recharging. Recharging a pair of batteries takes a couple of hours.Obviously, I can buy a boatload of "disposable" batteries at Costco for what I paid for this Pocketcharger and two sets of rechargeable batteries, but I went this route for my convenience. I highly recommend this charger.

I really think this is a great invention. Works well and quickly enough to alternate two sets of batteries over and over again. Unfortunately, the Power One rechargeable batteries that I bought don't last very long. So that is a drawback especially if you have trouble loading the batteries. I would estimate that the batteries (at least the two sets of batteries I was shipped) last only 1/4 of the time as a Power One non rechargeable battery. Nevertheless, it is very easy to use and very easy to carry around in purse or pocket.

I was extremely disappointed due to the short time the rechargeable batteries ran my hearing aids. The ones that were throwaway 312 batteries lasted more than a week at 10 hours per day minimum. The rechargeable Power One batteries last less than 7 hours in the same hearing aids. I bought three sets of 2 rechargeable batteries and the charger. I have Tweak Hearing Aids. The only advantage is that I will not have to buy throwaway batteries any longer (until the rechargeable ones fail). The charger seems to work as advertised, but have not tried charging with the onboard battery as I always leave the charger plugged in. I have not tried to find out how many batteries I would have been able to buy for the price of the charger and how many months they would have lasted versus buying the charger and the rechargeable batteries. Perhaps another time when I have a few minutes.
