Review on 16.8V 1A Power Adapter Li-ion Battery Charger With LED Indicator | 5.5 x ⚡️ 2.5 2.1 mm Interface | Suitable for 14.4V 14.8V 16.8V 4-String Lithium Battery Pack | NOYITO by Omar Chavez

Used twice. No longer works. The red charging indicator flashes quickly, dims when connected to the network and does not light up intermittently. It doesn't load at all. I looked at many chargers and settled on this one because its specs (input/output) are specific to the device I needed to charge. I will try to refund or replace it but my hopes are low as it has been some time since I ordered it.
