WRYY282 Posted October 17, 2023 Report Share Posted October 17, 2023 re: Power requirements for KG-XS20G+ I'm new to GMRS and purchased a KG-935G Plus. I'm contemplating adding a KG-XS20G Plus to use as a base station at multiple locations. I would have more flexibility using a portable battery setup rather than using a 30A Switching Power Supply plugged into an A/C outlet. I think the Jackery 300 Plus has enough juice to power a 20 watt mobile GMRS radio for 12 hours. It appears I could use the Jackery car port for the KG-XS20G+ for power up to 12 volts and 10 amps. Do most people use this type of set up for a portable base station? I may also use the KG-XS20G+ in my SUV occasionally plugged into the car port but will not drill any holes.

WRQC527 Posted October 17, 2023 Report Share Posted October 17, 2023 Jackerys are really neato, but you're paying $400. I use a 35 ah AGM battery with a charge controller and two Harbor Freight solar panels in the field, and it sits on a battery maintainer at home. The whole setup was less than $150. I use it to run a Yaesu FT-891 and an FTM-7250. Something to think about before you drop twice what the radio cost. Quote Link to comment Share on other sites More sharing options...

WRYZ927 Posted October 17, 2023 Report Share Posted October 17, 2023 I'm running a UV-25×4 with a Goal Zero 200x, temporarily, it works. Somewhat similar to you, @WRYY282, my intention is to build a "portable mobile" in an ammo can type of contraption at some point in the near future. I'm on the steep side of the learning curve at the moment but it looks like most of these mobile units call for 13.8v. I haven't fully started my research yet, but I'm planning on logging TX wattage/voltage/time. If I'm tracking correctly, running off of a battery at around 12v should lessen output watts compared to an optimal 13.8v? Quote Link to comment Share on other sites More sharing options...

I'm pretty sure 50W radios would not work, especially since they do not come with a car port. I'll keep researching. My backup is to use an A/C power supply with a long extension cord.

SteveShannon Posted October 17, 2023 Report Share Posted October 17, 2023 I have a friend with a Jackery as well. A Jackery is neat, but a poor substitute for a battery. The car port limits current to 10 amps, which isn't enough for a 50 watt transciever. If you crack it open and hook up an Anderson PowerPole extension, directly to the battery it would be more useful, but a battery in a battery box with Anderson PowerPoles is much more flexible: https://www.dxengineering.com/parts/wmt-58513-1403 Or this one from Gigaparts - it doesn't have PowerPoles but PowerWerx has fittings that might be useful: https://www.gigaparts.com/explorer-deluxe-battery-box.html and the batteries to put in it: https://www.gigaparts.com/p04power-12v-12ah-lifep04-battery.html or https://www.gigaparts.com/po4power-12v-24ah-lifepo4-battery.html Unfortunately both of those batteries are OOS right now, but if you look you should be able to find something similar elsewhere.

BoxCar Posted October 18, 2023 Report Share Posted October 18, 2023 A better radio choice is the DB-25G (Radioddity DB25-G GMRS Mobile Radio | 25W | Quad Watch | UHF VHF Scann) and for portable power, a battery box with a LifeO4 battery is much better. The radio draws about 8 amps while transmitting so a 1- 16 AH battery for less than $60 is a better choice. You can put in a box, like the Apache 3800 (3800 Weatherproof Protective Case, Large, Black (harborfreight.com)) and a cigarette socket (Amazon.com: CERRXIAN 12V/24V Fixed Thread Cigarette Lighter Socket Extension Cable,20A 13AWG Waterproof Cigarette Lighter Female Socket Replacement Cable-0.3m/1ft : Automotive) sets you back about $120.00. You'll need to put connectors on the cable to connect to the battery, but the socket can be used to both power the radio as well as charge the battery. All total, including radio is around $250 without the antenna. WRXB215 1 Quote Link to comment Share on other sites More sharing options...

marcspaz Posted October 18, 2023 Report Share Posted October 18, 2023 With that radio and inverter, you can run full power for 7 hours... though, the battery would be worthless when you're done. At a 50% duty cycle, you would get closer to 14 hours. For intermittent use, sky is the limit when you have solar. I have a 50 Amp hr LiFePo4 battery and 100w of solar. I can (and have) run a 50w radio and a 100w radio, with accessories and lights for overnight, continuously. So, im pretty sure that while the Jackery 300 is about half the rated power as my setup, with that radio, you should be fine. Quote Link to comment Share on other sites More sharing options...

A car’s electrical system puts out approximately 13.8 volts while the engine is running. The charging voltage can be somewhat higher, even up to 14+ volts. That drops to about 12.5 when the car is turned off. Mobile radios must be able to accept all of these different voltages, but they are usually optimized for 13.8 volts.

WRYY282 Posted October 18, 2023 Author Report Share Posted October 18, 2023 Thanks for all your input! I'm hesitant going with the Jackery and now leaning toward getting the DWC30WIN 30A Switching Power Supply. That will allow me to get comfortable using the radio as a base station while plugged into A/C at all three locations I need. I'll use it in my SUV if I need to make it portable. I may revisit a portable power supply if the need arises.

WRYS709 Posted October 18, 2023 Report Share Posted October 18, 2023 Before I got a 120v to 12v home power supply, I used to use my 28Ah SLA battery Duracell PowerPort 600 for both home and portable use. Much cheaper than Lithium Ion but much heavier. I prefer the $109 mini-Mobile Radioddity DB20-G 20 watt, cigarette lighter plug, VHF/UHF radio (opens to 2 meters/70 cm Ham radio). The City of Malibu funds Go-Boxes with them for their residents "at risk!" With a cup-holder mount and Mag-mount antenna it comes in and out of my auto with ease.

WRYY282 Posted October 19, 2023 Author Report Share Posted October 19, 2023 I have more reasons for a mobile base station that is powered by a battery system, so I am back on the path looking for a battery pack system. Quote Link to comment Share on other sites More sharing options...

Although it’s not my preference, my friend with a Jackery 500 really likes his. He uses it with a 100 watt ham transceiver which draws 23 amps on xmit. They are convenient.

WRYY282 Posted October 19, 2023 Author Report Share Posted October 19, 2023 In the simplest form, is it possible to connect a 12V 10 Ah battery directly to the radio? Do you need something in-between the battery and radio? Would something like https://www.amazon.com/12-Volt-Rechargeable-Lithium-Battery/dp/B00JK06CK8?ref_=ast_sto_dp provide full power to a KG-XS20G+ https://www.buytwowayradios.com/wouxun-kg-xs20g.html ? Sorry about my ignorance, but I would like to get full power out of the radio without damaging it. What is the general formula to use? Are these type of boxes advantages? https://www.ebay.com/itm/203198203515?hash=item2f4f8e867b:g:BI4AAOSwLppdQbsV Quote Link to comment Share on other sites More sharing options...
BoxCar Posted October 20, 2023 Report Share Posted October 20, 2023 The 10 AH LiFePo4 battery will run the radio for several hours with 80% of the time listening. It could stretch up to 24 hours depending on how much time is spent transmitting. A better choice for a battery is this one from Amazon - https://www.amazon.com/XZNY-LiFePO4-Rechargeable-Suitable-Emergency/dp/B09QPX38GG/ref=sr_1_12?crid=PZ83AN1KXVYM&keywords=16ah%2Bbattery&qid=1697761072&s=electronics&sprefix=16ah%2Celectronics%2C145&sr=1-12&ufe=app_do%3Aamzn1.fos.18ed3cb5-28d5-4975-8bc7-93deae8f9840&th=1. It has twice the capacity at about 2/3rds the cost of the Dakota battery you chose. The Woxun radio you like is out of stock and a better choice (IMO) is the Radioddity DB-25G with slightly more power but many more empty channels to store repeater configurations in. The complete radio package from Amazon is $210 including antenna and mag mount. Add a lithium charger https://www.expertpower.us/products/epc125-5a and you are set. The only thing missing are the connectors for the battery to the radio. You'll need 2 1/4 inch quick disconnect spade connectors crimped to the radio's power cable. marcspaz 1 Quote Link to comment Share on other sites More sharing options...

Battery, charger and connectors look like the way to go! I'll probably head in that direction. Hoping I don't need to add fuses or other components to protect the radio. I'll have to check one smart charger I have at another location to see if it would work. Thanks for simplifying the required power requirements. I have a pair of KG-935G+ handhelds and the KG-XS20G uses the same menus and operates similarly, so my preference would be to wait for the Wouxun to come back in stock.

I have a circuit breaker on mine so I don't have to replace fuses in the field. SteveShannon 1 Quote Link to comment Share on other sites More sharing options...

The radio's power leads are fused so use those leads. Just put connectors on the end of the leads. Quote Link to comment Share on other sites More sharing options...
