hi folks Dave here today I have the
0:18
vomen flash speed 1500 on my workbench
0:21
this was sent to me by vomen for testing
0:24
I do not get any sales commissions or
0:26
payments for making this review so the
0:27
reason why I accepted this unit is it
0:30
has an unusual feature of a 1500 W AC
0:33
fast charge built in in theory you could
0:35
charge this thing up with your gas
0:37
generator and then turn the generator
0:39
off and continue running off of the
0:40
battery power of course it also has a
0:43
solar input so this unit has a 1548
0:46
lithium iron phosphate battery in it it
0:48
has a 12vt car outlet and it has two DC
0:51
outputs just curious let's see what the
0:55
like 12.7 something volts it looks good
1:01
on the input side we have a built-in
1:03
switch mode power supply for the 1.5 KW
1:06
fast charging that's an IEC AC input
1:09
receptacle right there I want to test
1:10
that to see if it really works this is a
1:13
200 W car charging or DC input port and
1:15
this is your Anderson style uh solar
1:17
input that's 400 WTS for solar panels
1:20
there are two USB ctype outputs it has
1:23
three usba outputs 5vt 2.4 amps as well
1:26
as a quick charge usba port and I'm
1:28
going to verify that there is output on
1:33
that 5 volts and let's try a USB of
1:36
solder here and just see what happens
1:39
ADP USBC let's plug that in see what
1:44
happens USBC is working great three AC
1:47
outputs for 1500 watts output and it's
1:49
110 volt 60 hure sine wave I've turned
1:56
outputs looks all right it's a pure sine
2:02
I think the noise is coming from the
2:04
scope most likely not the inverter
2:06
itself that waveform looks fine we're
2:08
getting about 110 volts RMS 60.2 htz
2:12
here we have a connection for a jumper
2:13
cable if you have that which I don't
2:15
have that this is for auxiliary
2:16
batteries voman sells an auxiliary
2:18
battery pack or battery packs that you
2:20
can stack up with this unit to expand
2:22
the capacity and I won't be testing that
2:24
in this video one interesting feature of
2:26
the flash speed 1500 is it includes this
2:28
sort of a storage bin or
2:31
trunk I think that's a really neat idea
2:33
you can put all your cables in there
2:37
so you don't have to worry about losing
2:39
them because they'll always be there
2:41
when you need them really cool feature
2:44
there's these handles built into the
2:46
side we have some pretty robust looking
2:48
ventilation here there's a fan behind
2:50
there and on the back there's an
2:52
integrated Lantern or flashlight with
2:55
levels as well as a strobing or
2:58
signaling option I have a connection to
3:13
Watts 19 Watts 170 300
3:17
400 okay 600 700 it's over 1,000 Watts
3:22
Now 1 1200 1300 1,400
3:25
wow yeah this thing is actually uh no
3:28
joke I must say I'm very impressed with
3:31
this unit already it says it will finish
3:34
charging in 0.1 hours that's like 6
3:36
minutes so 1531 Watts indicated
3:40
84% well they're telling the truth about
3:42
the fast charge I was a little bit
3:43
skeptical I could do 1500 watts they're
3:45
not kidding so if you have a gasoline
3:48
generator and you're having a power
3:49
outage you can charge this thing in
3:51
about an hour and turn your gas
3:53
generator off and keep going that's
3:58
impressive and yes it does have cooling
4:00
fans and you can hear them however at
4:01
1500 WS charge I'm not going to complain
4:08
whatsoever it's just been a few minutes
4:10
and it's already up to 88% so basically
4:13
as far as the fast charging capability
4:15
uh I have to give that a huge thumbs up
4:17
I'm very impressed it does exactly what
4:22
do okay we've reached 91% I've never
4:24
seen a portable power station charge
4:26
this quickly I think it's time to go
4:28
ahead and do some testing of the output
4:30
now okay quick AC load test just to make
4:32
sure the inverter is working we're doing
4:37
left I'm just using a space heater to do
4:40
the load testing and don't try this at
4:42
home I made my own temporary makeshift
4:44
cable here because it didn't come with
4:46
the Anderson solar cable so I just kind
4:48
of cobbled one together here with some
4:51
alligator clips I'm getting 126 ws and
4:53
just to be clear it's a separate input
4:55
there's three inputs the auxiliary
4:57
battery connection looks like a 8s
5:00
so it's got eight lithium iron phosphate
5:01
cells in series and I'm reading that
5:03
voltage on the auxiliary battery
5:10
port but can it cook that's the real
5:13
question I'm not a cook so I'm just
5:15
using food that was prepared for me but
5:17
I think it's good enough for the
5:26
test so I've got a 1,000 watt toaster
5:28
oven here with some bread and cheese and
5:31
vegetables on it then I'm also going to
5:33
steam some broccoli in this hot
5:39
pot okay I'm just running the Hot Pot
5:41
first and that's using about 500 watts
5:43
according to the readout of course
5:45
that's probably taking into account the
5:47
consumption of the inverter itself not
5:49
just the appliance 111 volts
5:51
approximately we're going to be right at
5:53
1500 WTS I'm going to put it on about
5:56
300 and I'll just turn it on
6:05
okay we're close to 1500 watts but not
6:26
quite well we're cooking now and I'm
6:28
just going to let this machine work and
6:30
see how it performs The Flash speed 1500
6:33
should be able to handle a 1500 W load
6:37
ventilation and I can tell that because
6:39
it's got quite a loud
6:41
fan many people complain about the fan
6:44
noise on these units but I don't because
6:45
I know that that fan is the difference
6:48
between a unit that lasts a long time
6:50
and runs at a good temperature or one
6:52
that overheats quickly and the
6:54
components fail so when you're pushing 1
6:56
and 1/2 Kow of power you really need
6:58
some kind of a fan because this is all
7:00
closed up inside of a
7:07
box I'm not too much of an expert on
7:09
steaming vegetables but I guess there's
7:10
a first time for everything
7:23
be well the bread is cooking the
7:25
vegetables are steaming and the unit's
7:28
running at 1,450 2 W of power so let's
7:33
performs currently we're at 1,455 WTS or
7:37
something like that and the voltage is
7:39
holding at 111 volts ac so that's pretty
7:41
good of course we only have 0.7 hours of
7:54
this okay it's been a while and the VTO
7:57
in 1500 states there 0.6 left still
8:03
1,455 WTS it keeps jumping around 66%
8:07
capacity actually I didn't charge this
8:09
thing quite all the way up I did that on
8:11
purpose so far it's working
8:15
well okay I think that uh bread is done
8:18
by now so I should be able to turn this
8:22
off well it turns out toasting bread
8:25
isn't the most difficult thing so the
8:27
bread is pretty much done looks t
8:30
however the vegetables are going to need
8:31
more time currently we're doing 519
8:33
Watts 1.6 hours of runtime left 61% on
8:36
the battery so far this flash speed 1500
8:38
is working pretty well my thinking is if
8:41
you have a power outage this is a great
8:43
sight to see especially if you don't
8:45
have to listen to a gasoline generator
8:47
running constantly if you use the
8:48
generator to charge that thing up really
8:50
quickly you can switch the generator off
8:53
and cook your food and run your
8:54
appliances and you don't have to listen
8:56
to a run all day I think this is an
8:58
amazing piece of technology
9:05
well I'm going to go out on a limb and
9:06
say that this broccoli looks to be done
9:09
and on the vomen 1500 still 1.4 hours of
9:13
run time left 523 Watts from the steamer
9:16
the toaster oven is finished running
9:18
still 54% capacity I was about 89% I
9:22
think when I first started the test so I
9:24
used about not quite half of the battery
9:26
capacity in doing this cooking here but
9:28
considering I can charge it right back
9:29
up in less than an hour that's not a
9:33
problem based on my experience with this
9:36
unit versus over 40 other solar
9:38
generators and power stations that I've
9:40
tested and owned I would say I would
9:42
give this one a solid thumbs up my
9:44
concern with solar generators and
9:46
Portable Power Systems is always the
9:47
long-term longevity of the product the
9:50
inverter does not struggle under a 1500
9:52
watt load and it can absolutely run
9:55
anything up to 1500 WTS the fast charge
9:58
feature really impressed me me and I
10:00
think that it's actually one of the main
10:02
points of the unit if you need something
10:03
that charges quickly please note that I
10:05
don't get sales commissions for sales of
10:08
this unit and I'm not paid for making
10:09
this review so I'm just sharing my
10:11
experiences and my opinion if you're
10:13
interested in buying the unit there's a
10:14
purchase link provided by vomen down in
10:16
the description as well as a discount
10:18
code thanks for watching my review and
10:20
thanks to vomen for providing the
10:22
product sample for this test
