My high use battery powered Eufycam 2c Pro and Eufycam 2 Pro cameras were draining at about 2-3% battery per day with one Eufy-branded solar panel.Two Eufy solar panels with a $10 Y-adapter worked, but at 2x $60 PLUS a $10 Micro-USB Y-adapter, it was $130 to charge EACH camera.INSTEAD, a single Shyueda solar panel replaces my $130 Eufy 2-panel setup.I have one camera hooked up to TWO Shyueda panels and it can stream video, with light, almost continuously and still maintain 100% charge all day.COMPARISON:EUFY: 2.6Watts, 5V / 0.52amp (from eufylife.com), $60each, slightly smallerShyueda: 4Watts, 5V / 0.8amp, $50each OR $80/3-pack, slightly largerCONSTRUCTION: sturdy, general fit and finish are indistinguishable from the OEM panels. The panel surface has the same bumpy texture, and the plastic frame is sturdy. Cord is flexible and sturdy, the MicroUSB connector clicked into my camera with the provided adapters. The single, rear, metal screw mount is identical on both, and the mounting arms are comparable in quality.FUNCTION: Charges FASTER than the Eufy OEM 2.6W panel.VALUE: awesome. replaced a 2panel setup for less than half the price.LINKS:Miro-USB Y-adapter: https://smile.amazon.com/gp/product/B07ZZ8PNQF/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1Micro-USB extensions:https://smile.amazon.com/gp/product/B07881TBL1/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1SHYUEDA 3pack:https://smile.amazon.com/gp/product/B09SY51Z1Y/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1EUFY 1pack:https://smile.amazon.com/gp/product/B08L3NN3W2/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
