GL.iNet Pocket-Sized Wi-Fi Travel Router

While this device does have a USB-C power input, the charger included is bulky and not ideal for travel. Please note that the required 5V/4A (20W) input is NOT part of the USB-PD (Power Delivery) specification. So if you were to use this device with a USB-C to C cable, and say, an Anker GAN charger, or an Apple 20 Watt chargers, you may run into issues as not enough current (amps) can be drawn by the device. *This is not a deal breaker unless you really stress this device, because I haven't seen it draw more than 8 watts in my tests, just be aware that this device may require up to 20 watts.* Most 20 watt chargers on the market with a USB-C plug support 5V/3A (not enough amperage) or 9V/2.22A (wrong voltage). 5V/4A was a combination typically used by Oneplus and OPPO smartphones (VOOC is the name for this). There aren't any USB-C adapters in the market that provide this combination, but there are USB-A ones that do. The OnePlus Fast Charge Power Adapter US is one of them, and some Anker (C and A) chargers that have USB-A outlets, like the wonderful 735 and 747 GAN Prime series do support the legacy 5V/4A combination (the important part is to get at least 4 amps at 5 volts, the voltage part is non negotiable, 4 amps is a minimum). Please note that you also need a USB-A to C cable that can support 20 watts. As far as I understand the USB specification, USB-A is capped at 15 watts, and Oneplus/Oppo developed their own cables that are a little bit thicker to support 20 watts. If you get any random, USB-A to C cable you *may* run into issues, particularly so if they are chipped, but it is hard to tell if this device will even respect E-marked cables (such as Cable Matters certified ones). So, the solution to get a compact charger with this device: 1. Buy an Anker 735, or 737 GAN prime chargers, they are great to have, or any Anker charger with a USB-A output that supports 5V/4A. I tried to search for USB-C ones that support this combo, and they don't exist as it is out of spec. 2. You can also buy the official OnePlus Fast Charge Power Adapter US for 20 dollars. Please don't buy any off-brand, non UL Listed chargers, it is not worth the risk. 3. Get a USB-A to C cable that can handle 20 watts. These are very hard to find. Oneplus sells them on their store for a ridiculous high price (they also support way more wattage now, this is called SuperVOOC), the old 20 watts ones are out of stock. 4. If you search for "Dash Charge Cable 5V 4A" you will find some generic ones Amazon that can carry this wattage, I am pretty sure they are not certified by anyone. Note: Previous GL.iNet devices worked at 5V/3A with is a very common USB power delivery mechanism (even predating USB-PD). There is no problem with using any USB-C to USB-C cable, as most power adapters support that combination. UPDATE: With 2 clients both doing a Speedtest, WAN over Ethernet, and a Wireguard connection, I haven't seen this device draw more than 7 to 8 Watts using both the built in and the replacement hardware I mentioned. I am not yet sure how to fully get this to draw 4 amps to truly test if the third party adapter solution works. Installing the `stress` package through the OpenWRT UI, and running it I couldn't get it to draw more power, so the main current draw in here may be WiFi 6 tx/rx and not the quad core CPU. The photo attached shows an Anker 735 charger with the generic high amperage A to C Oppo cable I mentioned, along with a Pluggable USBC-VAMETER3. There was no difference with the built in charger.
