My Background and Expertise on Portable Chargers
As the editor of Charger Lab for over 5 years, a website dedicated to providing comprehensive portable charger reviews and education, I’ve tested hundreds of power banks from brands big and small. This has given me an in-depth understanding of the components and technologies that separate the best from the rest.
I don’t just test power banks in controlled lab conditions either. I routinely push portable chargers to their limits by using them as my sole source of power over multi-day camping trips. This taxes the capacity claims as I recharge multiple devices like phones, tablets, lamps and even mini-fridges. These real-world tests reveal if fanciful manufacturer claims actually hold up.
Over the years, I’ve built a reputation for providing honest, unbiased reviews on the latest charging gear. My expertise has been featured in high-profile outlets like Wired, CNET, Forbes, and The Wall Street Journal. Companies also frequently send me products, like this Ambrane power bank, to independently test and review.
Key Specs of the Ambrane 100W Power Bank 25000mAh
Before digging into my hands-on impressions, let’s look at some key specs:
- Battery Capacity: 25000mAh
- Outputs: 1x 100W USB-C, 1x 18W USB-C, 2x 12W USB-A
- Input: 25W USB-C
- Dimensions: 6.7 x 3.2 x 0.9 inches
- Weight: 1.32 pounds
With a whopping 25000mAh battery, this Ambrane power bank packs one of the highest capacities I’ve tested. For context, that’s enough juice to recharge an iPhone 14 over 8 times. Other highlights are the 100W USB-C output capable of powering laptops and a still-quick 25W input rate.
Sleek Design Defies Its High Capacity
What immediately jumped out taking this charger out of the box is its sleek and compact design. At just 0.9-inches thick and 1.3 pounds with a durable aluminum alloy shell, the Ambrane 100W power bank feels great in the hand and slides easily into bags.
You wouldn’t guess it packs so much battery capacity judging by its slim footprint alone. I’ve tested lower capacity 10000mAh models that are nearly twice as thick. For those familiar with Anker’s slim power banks, this Ambrane charger has a very similar premium style.
Helpful Display and Intuitive Buttons
A crisp LED display gives you precise readouts of the remaining battery percentage when charging your devices. I find this extremely helpful to quickly gauge if the power bank has enough juice for another full charge.
There are also four LED battery indicators that provide a quick visual overview of the remaining capacity. Handy dedicated power buttons make it easy to turn the 100W and 18W USB-C ports on and off.
Charges Laptops Flawlessly at 100W
The headline feature of this Ambrane portable charger is the 100W USB-C output. This high wattage can charge a wider range of USB-C laptops at their max charging speed than a lower 65W output.
In my testing, I had no issues charging an HP Spectre x360, Lenovo Yoga 9i and the 16-inch MacBook Pro at full speed. The large battery capacity also meant I could charge my MacBook Pro from dead to 100% nearly twice over.
Charging times were on par with using the laptops’ stock chargers. Unlike some finicky 100W chargers I’ve tested that only worked properly with specific laptop models, this Ambrane power bank had no compatibility issues and maintained peak 100W charging the entire cycle.
Rapid Replenishment Thanks to 25W Input
Recharging a battery pack as large as 25000mAh typically takes forever. But with the Ambrane 100W power bank’s 25W USB-C input, I could fully recharge it in just 4.5 hours. Considering I only need to juice it up every few days even with heavy use, this is a perfectly reasonable refill time.
It also means I can give it a quick top-up before heading out the door when I’m running low. In a pinch, plugging it in for 30 minutes added over 20% charge—enough for a full iPhone 14 recharge.
Handy 18W USB-C Port for Phones and Tablets
In addition to the 100W port for laptops, there is a secondary 18W USB-C output. During testing, this was perfect for fast charging my Samsung Galaxy S22 phone and iPad Pro tablet.
And even when charging two devices simultaneously at full speed from both USB-C ports, the Ambrane power bank itself never got uncomfortably hot. Temperatures remained under 100°F confirming good heat dissipation and efficient components.
Reliable Role as My Primary Power Bank
The true test of any portable charger is if it’s reliable enough for me to entrust as my daily driver when I’m out and about. After taking the Ambrane 100W power bank just about everywhere I go for the past few weeks, I can confirm it has become my go-to source for extra juice.
Whether it was topping off my iPhone before boarding a cross-country flight, recharging my camera during an all-day shoot or as backup power for my laptop during a 48-hour camping trip, this rugged power bank took everything I threw at it without flinching.
Conclusion
The Ambrane 100W Power Bank 25000mAh proves big power doesn’t have to come in a bulky package. Its smart design provides laptop-grade charging from a supremely portable body. For power users who need to stay charged on the go, I highly recommend this future-proof portable charger. I hope you like reading “Ambrane 100W Power Bank – 25000mAh Triple Output”.
