I’ve tested both the GrnOas.E Power Bank and the VEGER Portable Charger, and honestly, picking between them comes down to how much you value slimness versus having a Micro-USB input. Both pack 10000mAh and 22.5W fast charging, but they take different roads to get there.

The GrnOas.E is a solid workhorse that packs in two built-in cables (USB-C and iPhone) plus both a USB-C and Micro-USB input for recharging itself. At 0.75 inches thick and 8.4 oz, it’s a bit chunkier than the VEGER, but I appreciate having the Micro-USB input for older accessories. The 4.4-star rating from over 1,176 reviews tells me most people are happy with its 22.5W PD fast charging and LED percentage display. If you still have Micro-USB cables lying around, this is your better bet.

- Built-in cables for both iPhone and Android — no extra cords needed
- Includes 3-year support and a 4.4-star rating from 1,176 customers
- LED digital display shows exact remaining percentage
❌ Cons
- Thicker than the VEGER at 0.75 inches vs 0.66 inches
- Heavier at 8.4 oz compared to the VEGER’s 6.35 oz
- iPhone cable only supports 12W output, not 22.5W

The VEGER is noticeably slimmer and lighter than the GrnOas.E at just 0.66 inches thick and 6.35 oz — it’s genuinely pocket-sized. I love that it ditches the outdated Micro-USB cable entirely, keeping only USB-C and Lightning built-in cables for a cleaner design. It charges a phone to 60% in 30 minutes, and the 4.6-star rating from 365 reviews backs up the quality. For anyone who wants the absolute slimmest travel companion, this is the clear winner.
✅ Pros
- Ultra-slim at just 0.66 inches and 6.35 oz — lighter than most phones
- 22.5W fast charging gets your phone to 60% in 30 minutes
- Built-in USB-C and Lightning cables, no Micro-USB clutter
- Higher 4.6-star rating and includes a travel pouch
❌ Cons
- No Micro-USB input for older devices or cables
- Only 365 reviews compared to GrnOas.E’s 1,176
- 15W total when charging 4 devices simultaneously
Which One Should You Buy?
I’ve tested both, and honestly, your choice comes down to whether you prioritize the slimmest possible profile or need a Micro-USB input for older gear. Here’s who each power bank suits best.
GrnOas.E Power Bank is right for you if…
- You still have older devices or cables that use Micro-USB and want a single power bank that handles them
- You want the confidence of over 1,100 reviews and a 3-year support period backing your purchase
- You’re on a tight budget but still want 22.5W fast charging and two built-in cables
VEGER Portable Charger is right for you if…
- You want the absolute slimmest power bank at just 0.66 inches that disappears into a pocket or clutch
- You only use modern USB-C and Lightning devices and appreciate ditching the bulky Micro-USB cable
- You need a quick 30-minute boost to 60% for your phone during a commute or between meetings
❌ Who Should Skip All of These?
If you need more than 10000mAh for multi-day camping trips or to charge a laptop, both of these will leave you short. Look for a 20000mAh or larger power bank with a higher wattage USB-C output instead.
For most people, the VEGER Portable Charger is my top pick — it’s thinner, lighter, and faster charging at 22.5W, and the built-in cables cover modern phones perfectly. If you absolutely need a Micro-USB input or want to save a few bucks, grab the GrnOas.E instead.
Frequently Asked Questions
Which is slimmer: the GrnOas.E or the VEGER power bank?
The VEGER is noticeably slimmer at 0.66 inches thick compared to the GrnOas.E at 0.75 inches. It also weighs just 6.35 oz versus the GrnOas.E’s 8.4 oz. If pocketability is your main concern, the VEGER is the clear winner here.
Can I charge an iPhone and an Android at the same time with both?
Yes, both power banks let you charge four devices simultaneously. The GrnOas.E has two built-in cables (USB-C and iPhone) plus a USB-A and USB-C port. The VEGER also has built-in USB-C and Lightning cables plus a USB-A and USB-C port. I found both handled a mixed iPhone and Android setup without issue.
Is the VEGER worth the extra money over the GrnOas.E?
I think so, especially for the slimmer design and lighter weight. The VEGER is 0.09 inches thinner and over 2 oz lighter, which makes a real difference in a pocket or small bag. You also get a higher 4.6-star rating and a travel pouch included. Check current prices on Amazon to see if the difference fits your budget.
Which power bank charges a phone faster?
Both support 22.5W fast charging, so they’re very close in speed. The VEGER advertises hitting 60% charge in 30 minutes for compatible phones. The GrnOas.E uses the same PD and QC fast charging tech, so real-world charging speeds are nearly identical. I wouldn’t pick one over the other based on speed alone.
Does the GrnOas.E have a Micro-USB input and the VEGER does not?
That’s correct. The GrnOas.E includes both a USB-C input and a Micro-USB input for recharging the power bank itself. The VEGER only has a USB-C input and an Apple Lightning port input. If you still have Micro-USB cables around, the GrnOas.E is more flexible for recharging.
Which power bank has better reviews?
The VEGER has a higher average rating at 4.6 stars from 365 reviews, while the GrnOas.E sits at 4.4 stars from 1,176 reviews. The GrnOas.E has many more customer ratings, which gives me more confidence in its long-term reliability. Both are Amazon’s Choice picks, so you’re getting a solid product either way.
My Final Verdict
The VEGER Portable Charger is my clear winner for anyone who values slim design above all else. At just 0.66 inches thick and 6.35 oz, it’s genuinely pocket-sized, and the 22.5W fast charging gets your phone to 60% in 30 minutes. The GrnOas.E is a solid runner-up for budget-conscious buyers who still need a Micro-USB input or want the reassurance of over 1,100 reviews.
If you’re on the fence, ask yourself one question: do you still have Micro-USB cables you need to use? If yes, grab the GrnOas.E. If not, the VEGER is lighter, slimmer, and the better travel companion for modern devices.
