imutoPower Bank 65W Fast Charging 20000mAh Waterproof Portable Charger with LCD Display, DC port Emergency Backup Battery Charger with LED Torch for iPhone, Galaxy, Huawei, Switch, Tablet, outdoor

I do fun things so you don't have to. And in this case, the fun thing was that I tested both ports of this power bank to see what charging protocols they supported, make sure that they could hit their spec'd voltages and currents (and therefore wattages), and to do a discharge test to see if the capacity number is real (for a lot of off-brand power banks, the capacity number is a lie ... but spoiler on the rest of my review: THIS POWER BANK MEETS ALL OF ITS SPECS (and is generally excellent)!.First things first:The USB-C power can do 65 watts in and out, as claimed. It supports USB PD, with PPS, so it will 'super-fast charge' a Samsung phone. It also charged my HP Zbook Studio when the laptop was off, but wouldn't do it when the laptop was on (I *think* it's because the zBook gets confused by in/out port on the power bank and tries to transfer power in the wrong direction). This power bank actually follows the USB PD spec and doesn't support older QuickCharge variants on its USB-C port ... and while that is the *right* way to do it, it does mean that this USB-C port will not fast-charge some older USB-C devices that don't support PD (everything made in the last few years should support it, though).The USB-A port also meets its specs, and supports every charging protocol under the sun. See the photo of my USB analyzer plugged into it for the whole list of protocols. They've definitely go their bases covered here.The capacity measured out to just over 64.5 watt-hours at my DC load, which means that this thing is delivering around 88% of its internal battery's rated capacity to the device being charged. That is simply excellent. That means that the internal boost converter used to generate the output voltage is probably > 90% efficient at the 15W discharge rate that I used ... and it shows, this thing doesn't get hot when charging. Much better than virtually every other power bank I own.Finally, this has a 'trickle charge' mode that can be accessed by double-tapping the power button. This allows you to use the power bank to run devices that draw very little current and that the power bank might not normally detect. Things like earbuds, or devices that use USB as a power supply -- things with very low power requirement. This is the first power bank I've had with this feature, and it's a GAME CHANGER for me. I have tried to use power banks to run my kids noise makers (for sleeping) during power outages in the past, and they've all shut down due to low current draw ... but this one will stay on with just my USB analyzer plugged in, which draws virtually no current. Absolutely excellent!Lastly, an aside on power bank reviews: on this power bank and every other power bank you'll find some rocket scientist who plugs in an analyzer, discharges it, and sees that the amp-hours don't match the specs. I've even seen major YouTube channels make this mistake ... but the issue with that is that amp-hours aren't a measure of energy capacity. That's watt-hours, and I'm happy to see that this power bank provides that number on the back -- 74Wh. The number of amp-hours that you get from a 74Wh battery depends on what voltage you take them at. The capacity is rated based on the 3.7V nominal voltage of a standard Lithium Ion battery (20,000mAh) ... but since nobody every discharges at 3.7V, you can't compare the amp-hour number given by a USB meter to that given by the spec sheet. Think of it like a transmission -- I might have a battery rated to power the input shaft through 1000 full revolutions (roughly the mechanical equivalent of 'amp-hours', in this scenario), but without knowing the ratio of the transmission, I can't know how many revolutions I'll get on the output shaft. The boost converters used to generate charging voltages in power banks perform very similar conversions, and cause similar problems problems when attempting to compare the amp-hour rating of the battery with the amp-hour rating used on the meter.

Habe mir diese Powerbank zugelegt weil ich etwas Robutes brauche was auch mal einen Regenschauer ueberlebt. Powerbank ist super. Hat ohne Probleme mehre Feldmissionen mit Regen überlebt.

den laddar min laptop och kan laddas med olika 12v-20v laddare med motsvarande kontakter.

L'ho acquistato per fare un regalo e devo dire che è stato molto apprezzato. È molto comodo per quando si viaggia o si fanno gita fuori porta o si sta fuori tutta la giornata. Il cavetto ha uno spinotto che necessita di un adattatore in quanto non è compatibile con porte USB.

La uso principalmente para cargar mi Asus ROG ally y le da sus 65W para poder activar el modo 30W en la consola, se le acaba rápido la batería descargando a 65W pero es normal porque está cargando muy rápido. Se puede recargar por USB C o vía placa solar, es una maravilla.
