Charging a powerbank. Charging a phone directly doesn't work as well in the UK and my phone keeps switching charge state as the suns angle of incidence and cloud cover changes. Using a USB charge monitor, the panel delivers a much greater charge to the Anker powerbank than all my other powerbanks. Yes, that's the one. Even on a bright overcast day, it'll easily output over 2 amps. It's a heavy setup though, needs at least a week away from charging sources to start becoming practical to use. I'll be pairing it with a 6'000 mAh Anker for long term use where I'll be charging camera cells, phone, 18650's and maybe a tracker if I move away from Spot and it's replaceable cells. FWIW, I prefer the 2 inputs. Means you can use a not so modern USB output on the train/bus/airport/car/air bnb etc and doesn't rely on such a good quality cable.
FWIW, found one advertised as QC 3.0 for £2.59 on ebay. 20cm cable, can max out all my 18W plugs and weighs only 10g.
I do now after seeing the disparity in speeds. I only have one of the cheapo in line USB testers but the power-z fl001 super looks amazing and is only £14.
Oppo's superfast charging coming to Anker. https://www.pocket-lint.com/phones/news/oppo/155805-oppo-vooc-anker-vw-audi
I I've had an Oppo phone since August. It's fast charge time with supplied charger is great. And the capacity/battery life far better than any of the other phones I have had (2x plus)(Sony and Motorola in last 5 years) For the money I've been very happy.
Even if one doesn't have an Oppo phone, it will still help everyone, when they can fast charge Anker Power Bank in super quick in the future while resupplying.
