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

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.

Don’t listen to any negative nonsense about this unit. It’s likely due to user error. I’ve had this for a few years now and it’s still going strong. Recently, it was in my car for almost a year (I’d misplaced it). Despite extreme cold weather and extreme heat in the summer I just plugged it in and it still works perfectly. How many electronic devices can any of us say that about?

In short, you get what you pay for. This thing really does it all. I've tested out the AC outlet which can output the advertised 100 watts - Impressive. The on screen display is useful to monitor output levels and the inclusion of a temperature reading for peace of mind. The ability to charge the device from the USB C port or barrel connector DC port is awesome. I was able to fully charge the device in no time using a 60 watt USB C charger, providing 45 watts of input to the device. The Qi wireless charger outputs a full 10 watts, which is nice and charges compatible devices quickly.Overall, I'm very happy with the device. My one and only gripe is the included documentation that came with my device was lacking. The user manual provided very little information, hopefully they can revise it in the future.Update: I was also able to verify the 72 Wh rating using a USB C current and amperage measuring device. The device continued to take 10 watts of power input even though it reported being at 100%. I'm sure this is fine for the device as each cell is individually protected, most likely just a firmware / software issue with power reporting. Make sure you wait until the device isn't pulling any more power to make sure you're fully topped off!Two year update: Still going strong! I’ve been putting the adjustable DC port to good use(which is honestly it’s best feature in my opinion if you know how to use it properly, I bought a cheap 5.5mm x 2.1mm to 5.5mm to 2.1mm cable with some adapters). I’m guessing I’ve cycled the battery around 100 times, and it’s capacity has not noticeably diminished. Still highly recommended.Three and a half year update: Still kicking. Cells have degraded by about 15% of their original capacity after being cycled countless times, but the unit still delivers all rated wattages no problem. I’ve used solar panels to charge it a few times out in the bush and it’s worked perfectly.Four year update: Well…. I guess this is where the journey ends (kind of). I finally lost the thing (I think I may have left it in a hotel room on a recent trip). I’m not a happy camper. I debated purchasing some competing products to replace it, ranging from the Anker 737, to the Shargeek Storm 2, and other off-brand alternatives. I won’t lie, the $250.00 price tag is a hard pill to swallow, but after some deliberation and thought, I’m going to pick up another. It was that good. It’s form factor, compact size, ability to charge at a relatively fast 45 watts and output 60 watts from the USB C port, 100w AC port, ability to be recharged from a wide voltage range from the DC input (Like I mentioned previously, I used a solar panel out in BFE to charge it up using a 12v panel with an MC4 to DC 5521 adapter), the convenient wireless charging, highly versatile adjustable voltage DC output functionality, and high build quality justifies me dropping the cash on another one. Sorry wallet. I guess I’ll check back in again in six months to a year to let you all know if the new one is performing as well as the old one.
