AOHI 140W PD3.1 Laptop Power Bank 40000mAh Fast Charging Station, The Future Starship 2 in 1 Camping Large Portable Charger for MacBook Pro/Air, iPad Pro, iPhone 16 Pro Max,Galaxy,Steam Deck, Grey

100w is plenty to charge most devices, excluding items like the Macbook Pro 16". Only real limitation is the two ports on the edge. 1 USB C and 1 USB A covers at most, two devices for charging. only the USB C can charge at full speed. The device is large and is over the Airline Safe limit of 100Wh (27000Mah), at 108Wh (30000Mah). Its better for long car trips or being placed in a backpack. I would not recommend holding this in your hand while you charge your phone. After a few drops, the casing does start to move as its only plastic on the edges and not full metal. its not broken, but the casing is not as sturdy as it once was. I will admit that I have dropped this from multiple heights and multiple surfaces, so 1-2 drops from phone height is okay, but please don't go out of your way to drop it.Its a nice, well built power bank that will take a few drops, but is not invincible and only has two ports for charging devices and only one to charge the device itself. If you need a large power bank to power 100w USB C devices, this is a good product that should last you a few years.

This is probably the best portable charger I own, and I own four, it’s compatible with everything Ive tried, laptops, phones and handheld gaming PC’s. I 100% recommend this high performing portable power bank to anyone in any situation. The only down side is, it’s a little heavy for its size.

FINALLY, a USB power brick that looks professional, and performs as advertised, and above all: is actually safe to use, from my experience, on long flights. I am very pleased.Pros:* wattage and battery cell capacity, when tested by me, are very much on-par with specifications* SIMPLE, and very professional engineering: there are no gimmicky/embarrassing baloney on this device such as built-in flashlights, LED readouts, toggle switches, hooks, cords, dog leashes, mace dispensers etc., and/or internal nonsense like buzzers, beepers and/or crappy battery cells. This one, honestly, is properly engineered, and withstood six months of heavy use by me.* Looks professional: It does look as pictured. Reminds me of something I might purchase from a certain high-end camera company beginning with "N."* Faster than expected recharge time when using a 65-watt USB-C wall charger (but... no wall charger is included with this unit).* High quality USB-C cable included with the unit--more durable than I thought it would be.Cons:* wall charger sold separately, but any USB-C wall charger will indeed charge this thing.I bought this to power my ancient 2014 15" Apple MacBook Pro. This computer is terrible with power efficiency and is actually capable of actually drawing 90 watts when all CPU cores are throttled to maximum capacity. This unit can handle the 90 watts, even when my laptop battery is completely drained. Takeaway: the unit is SAFE under this condition. It does not get hot (hardly gets warm) when drawing 90 watts for extended periods of time (measured by wattage readout on a not-included USB-C cable). This tells me it was properly engineered.Some things to consider:* if you wish to draw 90 watts, you MUST do so via the USB-C port. Reason: USB-A jacks can't handle this kind of draw. (This is not a limitation of the power bank. Rather, it has to do with a limitation of the USB-A jack itself--USB-A ports simply can't draw this much power--simple as that.)* Apple customers with old laptops can search on Amazon for, i.e. "USB C Female to Magnetic 2 T Tip" for a suitable adapters.* A USB-C to USB-C cable that contains a tiny LED readout for wattage draw at one of the two connector ends, is a really good idea. The company that makes this block also sells one of these.* A 65W USB-C wall charger handy to charge this thing VERY quickly. (I was super lucky, and bought 65W wall charger bundled with USB-C cable w/ LED readout, made by this same manufacturer, during an Amazon "lightening" deal.)Note for USA flight travelers: I had no issues whatsoever with TSA in multiple states.

SHORT VERSION: Capacity is about 92Wh, good for its size and weight. Can reliably deliver output at ~100W continuously throughout a discharge cycle without overheating. Outputs seem a bit limited (only one USB C and one USB A port), but in reality it handles simultaneous use fairly well. The display is very basic, but most people probably won't care.OUTPUTS - just one USB C and one USB A. Other batteries in this same market segment have multiple sets of both A and C. OTOH, when you start using those multiple ports simultaneously on the other batteries, you start to get all kinds of limitations - derating from 100W down to 65, etc. This AOHI device actually does a fairly good job when both the A and C ports are used at the same time - I was able to get almost 120W when using both at the same time (19.5V/5A, ~100W from the C port and 4.5V/3.3A, ~15W from the A port). However, that is a bit of a synthetic result because I was able to connect both outputs to lab instruments that allowed me to make fine adjustments to the output current until the battery bank turned off. Real world, normal devices like phones or laptops won't be able to negotiate the charge parameters in that same way.CAPACITY - at 20V / 5A, I measured 91.97 Wh, and at 20V / 2A, I got 93.42 Wh. Capacity specs in the product listing are 3.6V (nominal) at 30 Ah, giving a claimed capacity of the internal battery of 108 Wh. Assuming those battery specs are legit, 92 / 108 = ~85% efficiency. Not great, but pretty average.MEASUREMENT DETAILS - I tested this device using a lab-grade electronic load (HP 6060B) with a USB "trigger board" that controls the Voltage output of the battery bank. This battery is capable of delivering very close to a full 100W output (20V, 5A) continuously during discharge. If you have a device that can charge at 100W continuously (you probably don't!), this battery can deliver that until depletion without overheating or thermal throttling. It gets warm, but not overly so; still, I'd recommend keeping this battery out with access to free air when in use (not stuffed in a bag or purse), esp. when it's delivering high power.INFO DISPLAY - if you're a weirdo like me that wants to know all the details about which device is charging at what power, etc., then the display on this power bank is very limited. The only info you get is four small LEDs indicating remaining capacity in 25% increments. Other batteries show a numeric % remaining, and still others provide per-port details for Volts and Amps. Some even show info for which Power Delivery standard/protocol has been negotiated between the battery and the device. But for a normal person, the four dots is going to be fine.
