Best Portable Solar Aa Battery Charger

easily portable battery charger

Battery charger for up to 8 AA or AAA NiMH NiCd batteries. It also will tell you if a battery is no good. You can also completely drain a battery on it before a recharge, which extends the life and strength of the battery. The only setback is that this is not a fast charger, so extra batteries are needed if one is doing a lot of flash work with remotes.

Excellent compact solar charger. Very light weight and portable. When paired with the 220 bifacial panel it's a pretty tough to beat for it's size. Excellent camping buddy.

Best keyboard I have owned. No batteries. Solar charger doesn’t need a lot of light. I Have had one for a decade now and no problems. Bought another one for my house. The Apple made keyboards always break down after a couple years.

Lasts forever. Best value yet. The only thing is that the charger only charges one battery at a time.

This product is a full featured battery charger that works with AA and AAA rechargeables.

I started off with the Watson 4-AA charger and have moved up to the 8-AA charger... because I use it ALL THE TIME. I still use one-use brand name batteries for flashes, LED light banks, and wireless transmitters and receivers. But, everything else gets the Watsons; i.e., audio recording devices, mics, etc. They help bring down my battery costs... and throw less battery acid into the recycle bin. When I order new Watson AA batteries, I put a mark on them to indicate which batch they are. First group lifecycle = 1; second group = 2. I have up to three group lifecycles going on at a time. Why? Because you want to know which ones are at or near the end of their productive lifecycle. For me, they seem to last about 30 recharges each... After that, they do not hold the charge that well, nor sustain the delivery of power... and they are not supposed to do it. The 30 recharges I get are already value on value of savings. Even at the end of a lifecycle, I can use them for really low-level energy devices (like remote controls). I just recommend knowing when to get rid of them. The charger does make the batteries hot, from time to time. That's how it re-activates the acids in them. I have tried other brands of AA battery rechargers and they all get questionably hot. The only rechargers that do not get batteries hot are like my pro-level camera batteries, but those are way more expensive. For the price, these are priceless.

Best small portable speaker, battery, sound, fabric and look!

Best portable charger. I love the fact that it can be monitored thru wifi or Bluetooth

The AA battery charger I had before only handled four batteries at a time and did not have a refresh or discharge capability. Realizing that rechargeable batteries need to be fully discharged periodically I wouldn't buy anything else but this product from now on.
