Its been a year since and the product keeps holding the charge like a brand new.

The media could not be loaded. Buen material, la caja llegó en buen estado (sellada y sin golpes), dentro estaba el power bank con el cargador tipo c doble, el activador de garantía y su manual de instrucciones. El material me parece bueno, el aparato tiene un peso considerable. Acabo de colocar mi iPhone 15 pro Max a cargar mientras escribo esto y ha cargado bastante rápido.

The quality is very impressive.

I have one of this power bank I bought it at the swap meet for five dollars an after 7 years still works so I buy a other one same brand works perfec

I tested the performance of the 30W 27,000mAh power pack with a USB Power Meter and, unlike many competitors, it does everything it claims! It is a better quality power pack than much of the competition but has a few quirks.Note: The 27,000mAh Imuto is allowed on commercial airplanes because it is labeled as a 99.9Wh power capacity which is less than the maximum 100Wh permitted by the FAA (max 27,027mAh = 100,000mWh / 3.7V, see "Nerdy Details" bellow for more info).Pros:1) Unlike most of the competing power packs in this price range and capacity category, it functionally does all it claims!2) Provides 85% output (85Wh) of its rated 99.9Wh capacity (27,000mAh). Most power packs are labeled in a way that inflates their capacity rating but really only provide 75% of the labeled output. (See "Nerdy Details" bellow for more info)3) Has reliable safety features.4) Though very terse and picture-oriented, the User Manual is comprehensive and provides all of the basic information to understand the meaning of screen display-icons and even how to reset the power pack to clear safety errors like "Over Heating".Cons:1) The USB-A ports do not reliably handle the initial Quick Charge (QC) handshake protocol and often had to be reconnected to get the higher wattage QC output flowing. Luckily the screen displays a single-lightning-bolt icon (rather than a double-lightning-bolt icon) when ONLY the lower wattage output is being used and so you have a clue something is not right. However if the USB-C port is simultaneously being used to provide PD high wattage output, a double-lightning-bolt icon is always displayed and you have no clue if the USB-A ports are properly using QC. This is the main reason I didn't give it a 5-Star rating.2) The Amazon "Product Details" claims the power pack uses internal lithium-polymer batteries but the unit's labeling and printed User Manual state it is using lithium-ion batteries. This may explain why it is so bulky and heavy (1.4lbs).3) The need to manually switch on "Trickle Charging" to continuously produce low wattage power output for devices like headsets and smart watches seems odd and should instead have been an automatic feature. Note it may not be easy to understand how to start/stop "Trickle Charging" and which specific USB-A port to use because the User Manual's picture-oriented documentation is so terse. Adding a couple of extra explanatory sentences would make this feature much easier to understand.Test Measurements:The 27,000mAh Imuto is explicitly labeled right on the unit as having 99.9Wh capacity. My unit has a measured recharge input capacity of 118Wh (equivalent to 31,892mAh labeling) and an output capacity of 85Wh (equivalent to 22,973mAh). This is a 28% inefficiency loss and is better than the standard 30% loss. The average of the measured input and output capacity values is 101.5Wh which is very close to its labeled 99.9Wh capacity rating. Its 85Wh output is 85% of its labeled 99.9Wh rating and is a significantly higher percentage output capacity than the competition. It has a maximum consistent output of 30W on the USB-C port when it is the only one used. It recharges using 30W input and only reduces the input to 14W when above 90% full and then finally a trickle-recharge to protect the power pack battery life.Test Equipment:I used a "Kowsi KWS-066C USB Digital Power Multimeter" to measure the total input/output Watt-Hour power capacity and real-time Wattage of this power pack. After an initial full charging of the power pack to 100% and verifying the input wattage was down to 0W, I tested a complete discharge and recharge cycle. To drain the power pack (output) I used a Lenovo ChromeBook laptop with "Adaptive Charging" disabled and did as many laptop 10%->90% charging cycles as needed. To recharge the power pack (input) I used a 65W USB-C PD (Power Delivery) charger. To connect these two to the power pack I used a 100W rated USB-C PD-2.0 cable with the USB power meter in-line (the USB meter is rated at a maximum 195W). Note it is important to use an appropriate wattage-rated USB-C cable for testing that supports the PD-2.0 specification or else the cable's internal microchip may throttle the wattage throughput to a lower value (any USB-C cable that supports 25W or higher must have an internal "E-Mark microchip" that specifies its wattage rating or, if the chip is missing, typically only 24W will be the maximum power pushed into the cable!).Power Pack Nerdy Details:(Skip this unless you are very bored)Watts (Wattage = Amperage x Voltage) are a measure of "electrical power" and Watt-Hours are used to measure electrical power capacity. Watt-Hours are used to measure the power capacity of systems like solar panels, storage battery systems, electric vehicles, and laptops. The true measurable power capacity of a variable voltage power pack is technically rated in Watt-Hours, not Amp-Hours, and this Watt-Hour value is typically stated in the fine print of their technical specifications. Nevertheless power packs are externally labeled in Amp-Hours as if they were constant voltage batteries because the typical retail consumer thinks of power packs as if they were big "smart batteries" and are accustomed to thinking about battery power capacity in Amp-Hours, not Watt-Hours.All power pack manufactures make believe their variable voltage power pack behaves like a big 3.7V lithium battery. They then calculate what labeled Amp-Hour value would make a constant 3.7V battery have the same total Watt-Hours as their variable voltage power pack. The labeling formula is "Ah = Wh / 3.7V" and for example a 100Wh power pack would be labeled as 27,027mAh (27,027mAh = 100,000mWh / 3.7V). This means the rated power pack mAh capacity can be directly compared to the labeled mAh capacity of standard rechargeable 3.7V cellphone lithium batteries and in theory makes it easy to evaluate how many times a power pack can fully recharge a cell phone.However there is a difference in the Watt-Hours required to charge a power pack (input) and the Watt-Hours a power pack can provide as output. There typically is a normal 30% loss of power output due to expected heat and electrical inefficiency in inexpensive low quality power packs. A best practice would be to label the mAh capacity of a power pack as the average of these two numbers but many manufactures instead label their product much closer to the higher input capacity number so their product stands out. This means the effective total power output capacity is often less than 85% of its rated capacity. This smaller effective output capacity needs to be factored in when evaluating how many times a power pack can recharge a cellphone.Watt-Hour, not Amp-Hour, is the only correct "measurable" power capacity for modern power packs which provide variable output voltage and amperage. For example, 10,000mWh of output power capacity can be generated by either "1,000mAh x 10V" or "2,000mAh x 5V". If you used a USB power meter to only measure the mAh output of a power pack and didn't factor in the voltage it was producing, you would incorrectly conclude the power pack that measured 2,000mAh had 2x more power capacity when in fact they both have the same power capacity. If instead you used the USB power meter to measure mWh you would see they both produced the same 10,000mWh of output power.

Does not work with starlink mini. I bought this because I watched a YT video touting this as the best battery to use for the starlink mini. I can say, it starts the starlink mini but it cannot keep it on long enough to connect to the internet. It loses power then drops and the starlink drops the network then reboots. I am not happy with this purchase.

So I purchased this specifically because I often find myself in situations where a wall charger is not a feasible option. It does appear to put out the power that is stated in the listing, and I believe the listed charge capacity is relatively accurate.Now, a couple of notes.1) This thing is big. And it is heavy. This is not going to go comfortably in your front pants pocket. Could it fit in baggier jeans? Sure. Would you want to? Probably not.2) Understand that 27000 maH is a designation of the charge able to be stored, NOT energy. What does this mean? Your laptop or drone battery does not operate at 3-4 volts like your cell phone does. Which means that "27000 maH" will be used up much quicker when charging a laptop or a higher voltage battery. In the case of charging a cell phone, it is more of a 1:1 ratio.It charges very quickly when given a proper high voltage charging source (65watt+) - in a couple of hours or so. In terms of its output and charge capacity, it's an excellent value for the money.
