Omni 20+ Professional Premium Portable Power Bank with AC Outlet 20,000mAh/71Wh,Laptop Power Bank,Universal Charger for All Devices, Fast Charging USB-C & QC 3.0, Travel-Friendly Power Solution

Most compact battery with the featureset
I camp and travel fairly often, especially to places that lack convenient access to A/C power. For a while now, I’ve had a powerbank I truck around with me when I travel, but it’s bulky, noisy (has a loud fan), and its power readout is vague. The specific use I had picked it up for was to use with my mini guitar amp so I could play at secluded gigs. The battery was about the size of my amp, so it was frustrating to have to deal with.I’ve watched the Omni 20+ since it was first launched, and after the reviews seemed stellar, I finally upgraded.First off, the size issue is definitely resolved. I’m already looking at fabricating a slot to hold this battery on the back of my mini amp. It’s the size of my hand, I couldn’t ask for more in that department!The wireless charging is neat, but unfortunately it’s a bit fiddly with my phone (I don’t blame Omni, that’s all Samsung’s fault for how they mounted the S22’s camera lenses). If you’re dead set on that, it’s maybe worth just bringing a regular wireless charger and hooking it up to the battery on a wire. It’s also worth noting that the wireless charging feature is tied to the USB power circuit, in case you miss that.The fact that the USB and A/C outlets are on different circuits is nice, though I’m hard-pressed to think of a reason to turn off one of the circuits instead of just unplugging the associated device.The readout is amazing. The stats are relevant and great for estimating battery drain if you need to manage your battery’s charge, or catching a device that draws more power than you expected.Honestly, my only issue is that it would be nice to have a cover for the ports (even a soft silicone plug would be enough) since I’ll tend to be using it in dusty places, or keeping it in a laptop bag where lint and clutter may accumulate. It’s a small thing, but at this price point it would have been nice.TL;DR: It’s probably the most polished, portable, and feature-packed battery pack you’ll find that still provides a 100W A/C outlet, and the brand has been around long enough to prove their quality.

I took my time reading and scrolling reviews before trigger my payment for this unit. I had a hard time to choose between the USB exclusive output model or this one (with AC & USB output), because the power on the USB is different. The concept it’s fantastic, I’m exploring everyday these features and it’s reliable . I believe only fine print issues may stop the Omni charge to state it’s dependable, but in my calibration and further tests. it was. A small example is driving 2 XPOWER FC-250D Pro 13” Brushless DC Motor Air Circulators and a the main floor air washer all set at max power for 3 hours !!! … was quite impressive.PS. Did I mentioned the design it’s probably way beyond the Apple’s standards … ? Every detail has a reason.

I purchased this product (actually 2… one from Amazon and the other from another retailer when Amazon no longer carried it in Canada). The one I purchased from Amazon died within the warranty period. When I attempted to charge it, it would always show an empty battery as the icon even after a day of it being plugged into the AC outlet. Contacted Omnicharge and it took them awhile to get back to me but they eventually did and after they determined that the product was defective (took ~1 month of back/forth emails for them to come to this conclusion), they sent me a replacement unit which was actually a better version of the Omni-20 that I purchased from Amazon. The one I purchased from Amazon didn’t have wireless charging built-in but the replacement unit that they sent me does have it.The one I purchased from another retailer is their higher end Omni-20 which can be charged by USB-C or the barrel connection cable that they include. It also has wireless charging. The version that I purchased from Amazon and was replaced can only be charged with the barrel connection that they provide.I now have three Omni-20 units (one of which is dead). I’m not sure what to do with the dead unit since it can’t be disposed of in regular trash so will need to drop it off at a battery disposal site when I get a chance.
