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.

This is a very handy charger that allows me to use only 2 sets of rechargeable batteries to power my hearing aids. The charger has it's own internal battery which allows you to charge two batteries when you are not near a power source. That said, the charger itself uses a usb plug for its power, so any computer or power brick that you have can serve as the main power source for the charger. The charger does come with a transformer that provides 1 usb port. When the charger is plugged in it will charge the onboard battery and 2 hearing aid batteries at the same time. Separate status lights provide individual status regarding the ongoing charge for the main battery and each of the hearing aid batteries. My hearing aids use 312 type batteries, which can reportedly be charged 1000 times each. Using throw away batteries I get about 3 days use. Whereas my rechargeables will on average last me 1 full day; occasionally if the environment is really working the hearing aids the batteries will give out an hour or so earlier. I just put the depleted batteries in the charger and drop the spare pair in. The charger is "smart", and will analyze the charge state of the batteries and determine the best charging strategy that should be used for each battery. It will top off a cell that only needs to be topped off, and will fully discharge batteries that are mostly discharged. Fully discharged batteries start charging right away. I do have some difficulty getting my hearing aids to start, sometimes when using the rechargable batteries, and this might be frustrating for some. The cause of the difficulty isnt clear, but gently squeezing the battery door for a few seconds gets the units to start. Speculation is that the batteries are either a slightly smaller diameter, or are unable to consistently provide initial surge-level voltages during the aid's power-up. Sometimes if the aids are jostled they will reboot. This appears to be an issue involving my particular hearing aids and the brand of batteries (Forza/OnePower) and is not an issue of the charger.

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.

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.

What a fantastic idea this. I will never run out of batteries again and will be freed from the need to find recycling points. Battery life is approx 1 day for my devices (which stream phone calls and music) whereas I get almost a week from disposables. However, I find I prefer that as I just change them every morning. Life changing and will pay for itself financially over time.

las pilas no duran casi nada

1. Unnecessarily product comes with multiple adapter with varied male input head. This will add a good amount of cost unnecessary. 2. Wire quality must be increased. 3. Very good concept. 4. Good product.

Plus que satisfaites de ce chargeur qui simplifie ma vie et m'évite d'avoir en plus des accus des piles . Très pratique pour emporter très plat il se glisse facilement dans un sac à main , le chargeur garde les accus accessibles à tous moments puisque celui-ci recharge sans être branché pendant au moins trois charges ( je n'ai pas essayé plus ) .Les adaptateurs pour différents accus sont bien pensés et pratique . Très très satisfaite je le conseille . Maryvonne

Expensive but saves buying all the little packs to trough away the batteries because they are so small last about 12 hours. I brought a stair pack of batteries so I a.ways have charge. Batteries will charge even when not plugged in from the battery inside the unit. Charged in about 2 1/2 hours
