Has anyone tested this to see if it does what it’s claimed to do, and what algorithm is used and how well it matches what it should be?
Pointer please if so.

It is highly irritating when there is no price by the product. Looks like you have to contact them for a price? I was interested but no price, no interest.

Is it AC or DC?

Measuring voltage in milliamps?

Voltage measured in volts but tolerance spec’d in milliamps?

Activation voltage measured in no units with a tolerance of milliamps?

When they can figure out the difference between amps and volts, I might consider giving their charger a look. Until then, um, no…

So — dead topic started by spammer? Or is there anything real somewhere behind the cloud of dust?

Thank you very much for you kindly help PilotPTK. I’m really sorry for my careless post of our new charger.

Input AC: 12V DC/1.0A When you use wall mount power supply to connect with the charger, it is AC to DC, so the input is 12V. But when you connect with car charger, it DC to DC, so the input is 12V DC.

Measuring voltage in milliamps?
Sorry, I wrote wrong for this one, the correct one is CV- Cut-off Current <100mA

Voltage measured in volts but tolerance spec’d in milliamps?
This one I also wrote wrong, the correct is: Auto Recharging Threshould Value Voltage: 3.9V ± 0.15V

Activation voltage measured in no units with a tolerance of milliamps?
Sorry, this one also typed wrong, the correct one is: Activation Voltage (battery voltage < 2V): 0.45 ± 0.15V

The price for this one is USD9.5/set. White or Black color.
Come with USB cable, price is USD9.9/set.

I’m sorry for my poor English here, and thank you very much for your kindly help.

hello Keith,

Sorry for reply to you until now. I’m new here and just learn to how to post here with my poor English, sorry for confused you. :frowning: Please kindly understanding.

The price for this charger is USD9.5/set, if need USB for digital products, then the price is USD9.9/set.

This charger left channel have Zero voltage read function, can auto charge if the battery is Zero votalge. Sorry, I don’t know how to show the pictures here.

The Charger will come with over charge and ver discharge protection function, it can take care of the battery safely, won’t cut the battery life, won’t make the battery inflatable.

And the guaranty is for 3 years. (Most charger only have for 1 year guaranty.)

Hi Iron,

NO, it’s not WP2.

I know, I mean WP2 II look alike.

Anyway, while since powerwholesale.net is down at the moment, I’ll place order coming Monday for some batteries, charger & other stuffs.
