Omnicharge Omni Ultimate Powerbank (USB-C, AC out, DC out, 12x18650)

So Omnicharge just released this:
https://www.omnicharge.co/products/omni-ultimate/

AC Outlet: 120W Pure Sine Wave
DC Out: 150W
Adjustable Voltage & Amperage
USB-C Port: 60W Max
2 x USB-A Ports: 5V/3A per port
DC Input: 90W
40,300 mAh (145Wh)
3 Hour Recharge Time
Removable Battery
11-Layers of Protection
Splash and Dust Resistant
Pass-Through Charging

I’ve been super happy with the original Omnicharge Pro/20, especially the adjustable DC output has been very handy. It also works superbly with a solar panel with fluctuating voltage and current. The Ultimate adds more capacity, power, pure sine AC output and adjustable current limit on the DC output as well as USB-C.

The downside: $299 for the early bird special.

Interesting product… Can you share a little more about the adjustable DC output?

Does it need special cords? Does the OLED screen measure current? General idea about efficiency?

Looks very handy and the range is great, I bet it can even decently charge a car battery, unlike those “portable jumpstarters” which only work when the charge is full and are useless below 60% charge.

The only thing I don’t like is (I suppose) they use NCR-B cells, pretty much outdated and not very good for heavy loads.

Interesting! You can now use a LED TV on a battery Smile

It looks like they have a proprietary connection on the DC out similar to the one that connects the replaceable battery to the device. Probably because a typical 5.5×2.1 or 5.5×2.5 mm jack isn’t meant for 70 V. It will probably come with an adapter cable with lots of tips just like the original Omnicharge.

The OLED screen at least on the current one tells you the consumption in watts drawn from the batteries (so includes losses). I measured the efficiency at about 85-90% on the Omnicharge Pro depending on load. Highest with the DC output charging a Macbook Pro (16.5 V) or with a 20 V DC load at 2 A which would indicate that the batteries have at least part of them in series (smaller voltage difference).

Btw, my Omnicharge has the NCR18650GA, which they probably use in this one as well.

Good to know, thanks! I’m a lot more interested now.

Cough….
I can make one, for cheaper, but not as beautiful
Just grab a car battery and a sine inverter, done :3
If you want to charge your phone, plug your adapter in, sime as that

Forgot my pen

They say the $299 is half off the normal price. I’d love to get one, but it’s on the expensive side.

Been there, easier said than done. A true sine wave inverter will run you about $100, not those fake sine wave at $30 or less and the inverter alone would be the size of this whole unit. You’ll need to either use LiFePo4 or a 12-24V inverter because 3S Li-Ion triggers LVP too quickly and 4S might be too high. Independent inverters with high output requires substantial load in order to maintain good efficiency, some can consume up to 30W while idle.

Ended up spending $200 for a 600W true sine wave inverter, in a wheeled toolbox with 125Ah AGM battery, 75V/15A MPPT solar controller for multiple input options, the unit weights about 100 lbs but runs very well and can be used as a UPS indefinitely by using a 350W AC-DC adapter on the input side. I’m going to post a build thread when it’s finished. It’s better than most “diy portable solar generators” out there spec-wise, but if I ever had to do everything again I’d just buy a goal zero yeti lithium instead, much more compact and can be easily transported around. Same applies with this Omni charge, many have attempted DIY power banks with adjustable DC out with little success, let alone 110V and 60W USB-C Power Delivery.

Put two wheelchair batteries in an ammo can, couple of usb ports and call it a day. Under 100 bucks.

Ah!

This is where you guys are half right, half wrong.

You can make a higher capacity battery pack for cheaper.

However, it uses lead acid cells, which you can only drain down to 50% SOC before losing a lot of cycle life, while you can drain down a lithium ion battery pack down to 10% SOC and have even better cycle life than a 50% SOC lead acid.

Second, his design only has USB A ports, not USB-C ports which can receive and output 60W of power.

3. It does not feature a pure sinewave inverter.

4. It’s much lighter.

I really don’t care about usb-c… or a built-in battery powered inverter. I’m strong enough to lift 5lbs. Had single one of these wheelchair batteries running my kids Gator (electric car) for several years before they outgrew it.. It would run for hours and hours before needing a recharge with a Deltran battery tender.

The only use I found for an inverter was to run my wood stove fan during a power outage in the winter. Have 3 deep cycle marine batteries, and each one runs the fan for 20hrs. All this stuff is still less than $600.

Backed the Omni ultimate with protective case and spare battery.

It’s a huge amount of $$$ for just 290Wh but AFAIK there isn’t any other product on the market that have the same output capabilities. And then there’s the 9-30V input with MPPT controller which makes it perfect for hooking up large solar panels.

I could’ve bought the yeti lithium 400 for less but I don’t really like the idea of 12V output by direct connection to a 3S Li-Ion pack. It means below ~60% charge you would be triggering LVP on 12V devices, some are set as high as 10.8V.
