Yep. You'd be amazed (if that's the right word) at how bad a modified sine wave inverter is. I had a XPower 1kw unit in my initial semi-off-grid solar system (only because it had been given

I'd do it the opposite way. Have a 12vdc 817 battery with a 12v to usb adapter. There are converters from 12 to 5 volts or an aux power (cigarette lighter plug) to usb. Mike

You'd probably be very surprised and disappointed if you look at a modified sine waveform. It's just a series of square top pulses alternating positive and negative. Same peak voltage as a sine wave

Hi folks, We had out doubts when other hams began espousing use of these battery banks, so we purchased a few and did some tests along with some well-known batteries to see how they stacked up.? We

Ron,? ?You'll never be sorry if you get a Weller butane soldering iron kit. It works anywhere and is especially good in cold weather for larger items like UHF connectors. Only the Weller one in my

" I have some good 6000 AHr units that put out 12V and USB (12000 AHr for USB), but have 3 Amp output limits. " You may want to check your units, LOL - got a good laugh reading about 12,000 Amp Hour

Greg, I agree we must always look at the AHr rating of the battery when getting one of these units, nothing new.? Even for 12V batteries for our rigs we need to check these ratings.? But the

Hi Ron, My caution is to not confuse watts with watt-hours. Getting a 300w unit only tells you the maximum instantaneous AC power that the unit will deliver, but provides no

Greg, Obviously one would not get one of these power packs to run like a refrig or heater.? I got a 300W unit to run my soldering gun for events like putting together Field Day.? Works great. Yes,

looks spendy? for a battery backup dave

I really like the RoyPow. I chased one down refurbishes then my brother, who is also a ham, apparently ran into them independently and got me another one for christmas to use with my FT817 and other

Mmmm, careful. At 88 watt-hours, that's barely more than 7ah at 12v, not counting internal conversion losses. The inverter may be able to source 100 or 300 watts, but not for long. 300

Martin, Yes there a lots of power banks that put out USB power and 12VDC power and also 120VAC power, all in one battery box.? I have 2 with 120VAC output along with USB and 12VDC outlets.? They

Nice that it’s multi-use but that thing is huge. Kevin -K5KTM

Hey Guys check your YouTube the channel from Jason KM4ACK this last Video bring s greatfully battery pack. https://youtu.be/VgeF4Zs2DuI?si=YjHvMklquMDYAhKv or when you have an Car Start helper this

Two ordinary 5 volt power banks of sufficient ah ratings wired in series creates 10 volts which is about the ideal voltage for the radio. Joe n1khb? Sent from AOL on Android On Tue, Mar 11,

There is USB-C, the connector standard, and USB-C PD which supports higher voltages and current ratings (like charging laptop batteries). If I understand the OP's desire, he wants a power bank that

Daniel. The answer to your question is? yes,, both the setups you sho will essentially work the same. 73, Bob GM4CID
