Vtoman FlashSpeed 1500 Power Station - taken apart, tested, capacity measured

[@NickyT-s2i]

I have same unit and I have no display and it will not charge any ideas ?

[@tedere]

question, 30 to 60 volt solar at 400 watts. What can the MPPT really handle, as 60 volts seams quite a lot, at only 400 watts, surly that MPPT could handle 1500 watts solar at 60 volts. Just a thought as it would charge just as quick as the mains plug.

I didn't notice any extra insulation between the cells, a bad sign...

[@MattyD-g8l]

You stated that the connector to add an additional battery is fairly common, what connector is it? I haven’t had any luck identifying it.

[@alexandrustefan9059]

I’m trying to identify it too, no luck until now

[@sergiiony]

What is model of battery inside? Eve 105 or 33140 or other?

[@jampam-jf8mt]

The firt press of ANY button turns the display on

It'd be nice to be able to change the charging rate on mains power so that you're not ramming power into the batteries, which shortens the life of the, low and slow keeps the lithium cells happy, though I'm not holding much hope of such a setting being available... :P

There is a few of them that doing it. The DJI I showed last time has two input options I think 600W and 1200W. At least one of the other big ones lets you adjust the charging power from the app, the DJI is on a nice physical switch.

[@jampam-jf8mt]

Vtoman Jump series have a separate charger and you can use a lower powered charger.

[@pradolover]

Could this be simulated with an old school segment timer, eg supply AC and charge for 15 mins, then disconnect AC and therefore stop charge for 30?

Was on the fence about getting this unit, primarily for the UPS function, to power some network switches and my pc setup, however some reviews lean towards that part of the unit not operating properly, changeover times etc. Perhaps you'd be happy to check this portion of this unit out, once your jumper leads are in. Wonder if the capacity test improves after a couple charge cycles or is this due to the inverter efficiency? Might lean towards a different unit, any of the bluetti, ugreen or other units you've looked at take the top, from your experience? thanks

[@DavidMcLuckie]

I shall add a UPS test to the next video.

[@vadym.ka5]

@@DavidMcLuckie Thanks for the detailed review! Does the Bypass work in the UPS mode or do use the battery? After a full discharge, does the station turn AC on when the greed appears at the input?

never seen one cut out so quickly trying to start a diesel heater , most at least try lol , I can cross this pack off the list 😁

[@DavidMcLuckie]

I need to test and see at what point it actually cuts out at.

[@frederick6008]

Where u been man

[@DavidMcLuckie]

Playing on bikes, the weathers been nice. :)

[@jampam-jf8mt]

Fantastic power station if you don't need to run a diesel heater. The jump cable is an optional extra but it's only £25
