can I connect a 12v router directly to a 12v battery which normally will be at 13-14v (because most of the time it’ll be charging)? The router is a TP LINK Archer MR200 rated at 12V 1A

    Use a DC to DC converter and, of course, a fuse. – Solar Mike Jun 10 '19 at 15:20
  • It's probable that connecting your battery directly to the router will be just fine. The router will work over a range of voltage even though they have not specified that range in the literature. However, it depends on the regulator built into the router just how high or low you could go. You'd be best to ask a question on the TP-Link forum or via Tech support as I'm sure this problem has been dealt with by them before. A DC-DC converter could solve the problem, but you'd potentially need a Boost/Buck version to cover the full range of battery voltages (say 11 - 14V), – Jack Creasey Jun 10 '19 at 16:14
  • There are plenty of Buck/Boost DC-DC convertors available, if you search for regulators based on the XL6009 in your favorite store you will find examples such as this: https://www.ebay.com/itm/DC-DC-Boost-Buck-adjustable-step-up-down-Converter-XL6009-Module-Solar-Voltage/201544467794 – Jack Creasey Jun 10 '19 at 16:21
  • it should be fine (connecting directly and right way around) but tp-link company will never inform you about that – Volodymyr Kalinyak Jun 10 '19 at 20:00
