Solar-powered rechargers

[wbswetnam]

There are times when, due to storms or other disruptions, that the power can be out for a considerable amount of time. I was visiting Washington DC in late July 2012 when a powerful derecho storm knocked out the power for four days. In anticipation of future events, recently I bought a 300000mAh dual USB portable solar battery charger on eBay for $14.00.

Would this be adequate to keep a low wattage scanner model such as the Uniden BCD325P2 charged up?

After reading the online specs 2 watt solar panel @ 5 volts the charging current is .4 amps (400 Mil) and it has a rechargeable battery and if the battery size is correct it would last about 20 times what your batteries in the scanner would last before running out of charge and would take weeks to recharge on solar power only.

Obviously I need a higher wattage solar charging panel. Suggestions?

I bought this foldable solar panel:

It has a MPPT controller and will charge a USB power bank a lot faster than a 2-watt panel

I've tested this battery bank and it's storage rating is pretty accurate.

Thank you for the suggestions, Jon. They look like something to consider.

300 amp hours is a straight out lie. 300 Ah times 3.7 volts is 1110 watt hours. That's a battery that occupies about 300 cubic inches and weighs over 15 pounds, so get your ruler and bathroom scale out.

If what you bought looks anything like these units Clive has reviewed, it's going to be garbage.

I bought it from a seller on eBay, so it's got to be another A-number-1 top-shelf super-duper high quality product from China!

OK so I lost $14...

It may be an additional zero, intentional or otherwise.

My $14 'solar' USB charger arrived this afternoon... complete piece of junk. Very cheaply made, only vaguely resembles the product in the advertising photo.

If there's a way to get a refund I'd go for it...14 bucks is 14 bucks. I haven't eBay'd anything in several years so I don't know.

But sometimes you just have to try something to see if it's any good. Sometimes you get nicked, and sometimes you wind up with a good value. I've had both happen many times and no doubt will have both happen many more times in the future.

I'm not gay, but...

Are you able to share the link to where to get this?
