Did you know you could recharge batteries without electricity?  That’s right, no electricity needed, a completely off-grid battery charger.  This is a cool product!  A fellow reader of this blog recommended I look into a prepper product that recharge batteries using salt-water created by Greenivative.  The company agreed to let me test the Double Power G-Mag® BarterPack in exchange for this review.

Review

I’m currently in the process of switching all my tech to rechargeable batteries. It was surprising to me how many battery operated electronics I have, as one after another died last month. I replaced batteries in my flashlight, wall clock, alarm clock, wireless keyboard, wireless mouse, thermostat, remotes, and smoke detector.  The importance of having a backup battery charger was not lost on me, as my awareness of how much I depend on batteries grew.

The first test was to make sure the charger really recharged batteries and if they would recharge a generic brand of battery. My walkie talkies had generic rechargeable batteries (labeled: CEL). The walkies also showed me how much power was left in the batteries. After letting two walkies drain of power (total of six batteries), I used the GMAG Saltwater Powered Battery Charger. I found it easy to operate, using a funnel to pour in the salt and water.  The batteries were completely charged in 5 hours and when placed back in the walkies, showed that they were fully charged. After the recharging was complete, I flushed out the device many times.  The flush removed the saltwater and black chunky residue. Throughout the month, I recharged depleted batteries several times using the GMAG charger.  It worked well every time.  There were only two only minor problems I came across. The first was that one or a couple of the batteries would pop off of the charger but after some finagling, the jumpy battery would stay in place.  The second is that I lost one of the plugs for several minutes and wondered if it would still work if the plug could not be found.  Overall I was impressed with the quality and function of this product.

Cons

  • Funnel not included
  • Price is a little higher than I would like
  • The USB cell charger didn’t perform well.  After charging a tablet all night using 4 AA 1000 mAh batteries, it only had 19% power in the morning.

 

 

Greenivative makes a few models ranging from $65-$199.  One model works with adapters that will recharge C & D batteries. Another model allows GMAG to generate power indefinitely by replacing a part called a PowerPuck. The package and model in this review are priced at $70.  For a full listing of their products visit Greenivative.com.
