Omni 40C+ vs Anker A1383: USB Power, Capacity and Travel Limits
The Omnicharge Omni 40C+ and Anker A1383 serve different laptop and phone charging needs. The Omni adds a data hub and higher individual USB-C output; the Anker offers a built-in cable in a smaller package. This comparison covers the standalone Omni 40C+ and Anker Power Bank (20K, 87W, Built-In USB-C Cable), model A1383. The Anker is not the Anker 521 power station.

Check the product name before comparing capacity
A listing name alone can hide a different battery, connector or generation. Match the model number on the device to its manual. A USB power bank is suitable only when the connected device accepts its supported output. Neither product replaces an AC backup system for household appliances.

Why the largest port number is not a shared power budget
Two outputs labelled 100W do not mean the Omni can deliver 200W simultaneously: its stated combined ceiling is 150W. Likewise, Anker’s 87W total does not mean a single laptop receives 87W. Actual negotiated power depends on the device, cable and other connected loads.
Before buying, check your laptop’s required USB Power Delivery profile and its demand while working. A laptop that charges when idle may discharge its internal battery under heavier workloads. A properly rated cable and the correct port matter. Verify display and data compatibility separately; an HDMI connector does not establish compatibility with every laptop or cable.
An illustrative runtime worksheet
Stored energy and charging power answer different questions. For the Omni, assume 80% of nominal energy reaches a constant 30W load: 142Wh × 0.80 ÷ 30W = 3.79 hours. At a constant 60W the same assumption gives 1.89 hours. These are planning examples, not measured runtime or laptop charge counts. Conversion losses, standby consumption and changing demand can alter the result.
For an mAh-labelled battery, use the nominal voltage associated with that capacity: Wh = mAh × nominal volts ÷ 1,000. Do not substitute the USB output voltage. For example, 20,000mAh at an assumed 3.7V equals 74Wh; use the actual A1383 label when comparing or travelling.
Air travel requires a separate check
Under the FAA passenger battery guidance, power banks belong in carry-on baggage. Batteries up to 100Wh fall within the standard capacity allowance; 101–160Wh require airline approval, with a limit of two larger spare batteries. The 142Wh Omni therefore requires that approval. Airlines can impose stricter quantity, storage and use restrictions. Verify your carrier’s current policy, including removal of power banks if a cabin bag is checked at the gate.
Which fits your charging plan?
Consider the Omni when its hub connections and higher single-port limit solve a specific workflow. Consider the A1383 when a 65W USB-C limit and built-in cable meet your needs. Compare current local price, warranty, cable replacements and return conditions rather than an unsupported numerical score.

I own the Anker 20,000 — super pocketable and the built-in cable is clutch for quick top-ups. But yeah, capacity vs the Omni is apples and oranges.
The Omni is more of a mini power station with extra ports and features; Anker is just reliable everyday juice.
If you need to charge a MacBook Pro from 0–100% regularly, Omni wins. For phones and occasional laptop top-ups, Anker is better for daily carry.
Nice summary, Priya. That’s exactly the positioning we saw: Omni for power-hungry or multi-device workflows; Anker for commuters and travelers who want light weight.
But if you’re mostly on planes, remember Omni’s 142Wh may trigger airline rules (some airlines stricter). Anker stays under 100Wh so no drama.
Good point Derek — check your airline. I had to declare a larger bank once and got a weird checklist but it was fine.
Agree. I take the Anker to work every day. Lightweight and fast enough for phone + occasional tablet charging.
I love the Anker for trips. The built-in cable is great but I keep a backup cable in my bag just in case. Peace of mind.
If you want both worlds, I sometimes bring the Anker for daytime and Omni for long remote shoots — extra baggage but worth it when I need it.
I actually carry both — Omni in the bag when I know it’s gonna be a long day, Anker in my pocket otherwise. Kinda ridiculous but hey, better than dead devices 😂
Haha appreciated honesty. Dual-carrier approach seems common among freelancers who need redundancy.
Great write-up — helped me decide!
I loved the detail about the Omni’s HDMI and SD card reader. For my remote video shoots that feature alone is a huge deal.
Yes, it’s heavier, but being able to power a laptop and have a little media hub is worth it to me.
Curious if anyone has used the Omni + camera setup on a day-long shoot? Battery life real-world impressions welcome.
If you’re running a lot of power-hungry gear, bring a spare battery for cameras. Omni helps with the laptop and accessories, but don’t rely on it as your only camera battery unless you tested it first.
That SD reader is underrated. I swear it’s saved me from carrying a separate dongle. Also, the USB-C 100W is no joke. 😀
I used the Omni on a wedding gig once — charged my laptop, a small light, and backed up SD cards via the reader. Not full-day for heavy cameras, but great for multitasking setups.
Thanks Laura — glad it helped! Several readers reported getting a full day of light camera/laptop use from the Omni on 1–2 charges depending on camera draw. If your camera has high draw, expect fewer cycles.
HDMI on a power bank? Are we living in the future or is this just a flex feature lol
Seriously though, what use-case is that for — direct camera playback or hooking a laptop without an adapter?
Totally a flex but also practical for content creators. Depends on your kit.
I used it to preview footage on a field monitor without carrying a separate HDMI dongle — saved space.
If your laptop is new and portless, little features like HDMI on the Omni can replace another adapter. I appreciated it once when my dongle vanished 😅
Short and sweet: Anker for commute, Omni for work trips. That’s my take.
Price vs value question: Omni is pricier but you get more ports and that extra power. I’m on the fence because sometimes I never even use the SD/HDMI but pay for peace-of-mind.
Also, tiny rant: shipping for power banks is always weird with online stores because of regulations — took longer than usual 🙄
If you rarely use the extras, consider buying used or during a sale. I snagged an Omni on discount once and felt better about the price.
Totally understandable. If you don’t need the extra ports/features often, Anker is usually the more economical choice. And yes — shipping/handling can be slower due to battery regulations.
Omni looks awesome, but 142Wh has me nervous for flights. I thought carry-on power banks had to be under 100Wh? Anyone navigated this?
Good question — many airlines allow up to 160Wh in carry-on with airline approval. Policies vary, so always check with the airline before flying. Declare larger capacity units when asked.
Yup, I once had to show the spec label at TSA for a >100Wh unit. No big deal but better to check first.
Anyone tested the OLED/status display on Omni for accuracy? Some banks overstate remaining charge.
I liked the physical ports layout though — ergonomic.
Can someone confirm if either supports pass-through charging well? I mean charging the bank while it charges devices at the same time without overheating or losing efficiency.
My workflow: laptop + phone while wall power is limited.
I used pass-through on my Anker occasionally; it works but it’s slower. If you need full-speed charging for a laptop while plugged in, Omni did better for me.
Note: continuous pass-through can warm the unit. Don’t bury it in a bag while doing heavy simultaneous charging.
I’ve been deciding between these two for weeks. Omni = all the nerd features I crave (SD reader, HDMI, 100W), but it’s kinda bulky.
Anker = minimalist and practical. I like having fewer cables and the built-in cable is a game-changer, tho I’m worried about long-term durability (some wear already).
Also, does anyone else get weird FOMO buying power banks? Like “what if my next phone needs more juice” lol 🤦♀️
PS: love the chart in the article — made the choice way clearer!
Haha FOMO is real. If you upgrade devices often, lean toward flexibility (Omni). If you want something low-hassle, Anker’s the safe bet.
FOMO club here. I ended up with Anker cause it’s easy to carry. Still tempted by Omni for weekend shoots though.
FOMO is an expensive emotion. I made a rule: if I can’t list 3 daily uses for a feature, skip it. Saves cash.
If it helps — pick based on your heaviest use-case. Don’t overbuy features you rarely need, that was my mistake last time.
Buy both, regret nothing 😆
I flip-flop every sale season. Pro tip: check trade-in/sale windows around product launches.
