To close the discussion for @Abhishek and @Syed on the Adafruit PowerBoost 1000 Charger - Lipo battery which I have successfully run for 2 hours with the ac USB power cube disconnected - -
Both chargers have worked continuously for 15 hours without overheating - - they run warm to the touch (not hot). They do work as an UPS with my Boston Power Swing 5,300 mAh. That said, as a practical consideration for Othernet’s marketing strategy, we’re operating too close to the device’s upper current limit of 1,000 mA in my opinion. The concept is valid, but there are other viable solutions such as an EasyAcc 20,000 mAh device that Zoltan proposed when he was with the company.
I have found a new device now on order from https://www.robotshop.com/en/mp2636-power-booster--charger-module.html - - a 2,500 mA capable Lipo charger I will test next week. With 2,500 mA capability, it should be able to run the Dreamcatcher and recharge a dead Lipo simultaneously. Ken
