Hi
Just bought 320 Plus.
I like to go to the woods where is no electricity and I was testing some field chargers what I have home.
All of the chargers I bought on Ebay.

Soshine is not working at all.
Soshine is rated 400mAh only. Looks like it is not enough.

Tekkeon is working very well. Rated 1A.
Charged from 0-100% in 2.4 hours from 4 Sanyo Eneloop 2000 mAh rechargeable batteries. There was still some juice in the Eneloop

El cheapo charger with 2 Duracell Stay Charged 2000 mAh rechargeable batteries works great. Needs to be charged twice, two batteries are not enough. Charged from 0-100% in 2.5 hours. Still some juice left in last two Duracell.

One more question for today.
Will 3x1.5V AA alkaline set for total of 4.5V kill the unit ?

If you want to continually monitoring outdoor, then a solar panel may be a better way. There are many 5V USB charger type solar panel available in the market.
The solar panel with a power bank together should work.

I have 20 W solar panel, power banks and all other hardware.
But not always is a sunny day in Philadelphia :)
Will 4.5 V DC kill the unit ?
Is just 0.5 V more.

The unit used 5V USB power to charge the unit battery.
The 4.5V should be OK.

20W Solar panel is more than enough. I think 3-5W should be OK with the power bank.

With a 5A power bank and solar, it should run about 20 days without sunny day.

It just needs 1-2 sunny day to charge the power bank and unit.

It is not working like this.
Charging voltage is different from working voltage.
I can charge my two way radio from 12 V car cigarette socket, but they working voltage is 4.5 V. 12V will kill the radio.
Somewhere in the technical specification/schematic should be that info.
Would be nice to be able to power it from 3 x AA alkaline batteries.
I already have project to make 3xAA power supply :)
