in reply to Peter Lord • • •@u3acommunitiescomputing@u3a.sociallooks useful !
Is that a particular brand, or was it a random choice from eBay / Amazon / AliExpress etc?
I see it fits Ryobi batteries. Are there models for other brands or it it adaptable to many?

in reply to Sheddi • •I got it on aliexpress ... similar devices are available for other tool battery types.
Plan to test it more thoroughly next week.

4Ah robi battery lasts for 3 phone charges.
5Ah robi battery lasts for 4 phone charges.
I guess not surprising.
With a 4Ah (18v) battery and a phone battery of 5Ah (3.8v). Number of charges = (4x18)/(5x3.8) = 3.7 (minus losses)
Might need to get a bigger robi battery for festival use ....
