HyperJuice 245W USB-C 100Wh Battery Pack, M1 MacBook, iPad, iPhone, and More, Fast Charger Type C 27000 mAh Power Bank, Portable Charger

I have a gaming laptop with very hungry 120V power requirements and on a flight even with brightness reduced to a minimum I’d have at max 2-3 hrs of battery life. This product gives me an extra 4 hours of power so I can game to my hearts content on long haul flights and functions exactly as advertised.

The HyperJuice 245W USB-C 100Wh Battery Pack, Fast Charger Type C 27000 mAh Power Bank --- I like to have the power bank with me when we do weekend travels and this is great for me to keep my laptop charged while I am doing a long ride, so the size of this power brick doesn't bother me. I can charge my 15.6" laptop have about 50 percent battery juice left. The screen showed 65 watt output.

The 100 watt-hour battery by HyperJuice is made in PRC (china). The battery is not the smallest form factor for a battery of this rating. The battery has a mostly aluminum case. My best case charging pushed about 85 watts into the battery. The best drain I could pull from the battery was 84.7 watts. I tried various cables, mostly rated for 240 watts, but did not find a known reference for what works best with this HyperJuice battery. Samsung, Apple, and Dell devices were tested. This is a good battery, but for the $200 price, I expected it to meet the expectations set in the item description. 4 stars

I need to do more testing but maybe twice now this battery pack has been under 50% charge, put away with nothing connected for a few hours and then it's dead when trying to use it again. Otherwise it's impressive and I love it. Hoping there's nothing wrong with mine. Update: I haven't had any further issues with this bank. It works great and it's the best charger I've ever used.

The HyperJuice can quickly charge many devices at fast speeds. It is longer than my 30000 mAh power but about half as thick. The major difference between the HyperJuice and my 30000 mAh, is the HyperJuice delivers power much faster. This is a great battery for a power user. The power bank looks nice and is made with quality materials. It looks and feels like an Apple product. The HyperJuice is on the heavy side and is suitable for a small sized purse or backpack. Although, you could stick it in your back/front pocket on the fly. The average power user wouldn't mind the size of this thing at all. My only gripe about this power bank is the inability to push a button to check the battery. You must plug something into the bank to turn on the power bank's display. If you want to check the power bank levels after plugging something in, you must unplug and plug your device back in to activate the screen. It is a minor thing, but it is worth noting. Overall, this is a genuinely nice premium made power bank.
