Only in one review: In test 50 W (SCP-35-12); Ripple 200 mV (Used QC 3.0 charger); Temperature rise 107 °C (SCP-35-12); Weight 123 g (Used QC 3.0 charger); Price 3.4 $ (Used QC 3.0 charger).

SCP-35-12: It works well as a charger, but is not recommended with a lead-acid battery unless discharge protection is added.

Used QC 3.0 charger: The used charger delivered the rated 8 A on 5 V, but QC is faulty and ripple under load is high.
