A guy who built the this circuit:

https://www.electroschematics.com/4746/solar-charger-circuit/

, says that the solar charger can be used for Ni-Cd, so I searched in ebay and I found this:

**broken link removed**

Can I use it instead of the Sealed Lead Acid, or will I face the problem that it needs 7,2 Volt to get charged and not to fall below 50% capacity?

Can I use a powerbank like this instead of the Sealed Lead Acid?

**broken link removed**

Generally, powerbanks are charged by 5Volt wall chargers, but I do not know if the current they draw can be handled by the solar charger...any ideas/suggestions?

Thank you
 

Hi,

in the EU NiCd batteries are not allowed anymore (there are only a few exceptions).

So, does it make sense to build a charging unit for that?

The powerbank with a Lithium battery has an input from 5V to 12V, at 2A. It has the charger circuit inside it. It comes with a Chinese user manual so you must translate it yourself.
