ZMI Plugornot Zero Portable Charger 6700mAh with Dual USB Wall Charger, Foldable Plug and Quick Charge 3.0, Battery Pack for iPhone, iPad, Android, Samsung Galaxy and More

The plug is too thin to fit properly in US sockets.

I have a couple USB-powered devices that do not have batteries, but which I want to be able to ride out short blackouts and the like (such as a pet water dish that circulates and filters the water).So far this device fills the need nicely. It can charge while providing power output (most 'power bank' devices I have tried can not do this), and it stores enough power to keep what I have on it running for about 16 hours. Not too bad, and the nominal 23Wh probably isn't far off based upon the spec for that pump motor.At this point in its life, I think it was worth the money. If it still reliably holds most of the charge toward the end of the 18-month warranty, I will still think so.It has three quirks I don't like, but that are, for me, only minor issues.The charge indicator seems nonlinear. Unplugging it to see whether it would switch automatically and then leaving it to see how long it would run, I observed that it ran about 8 hours before the highest charge bar went out, then four or five hours for the next, two or three hours for the next, and when the last one was gone, it was no longer powering the load.It cuts power to the load momentarily when it switches between charge/line-power and self-power mode. Basically, the load loses power for a few seconds whenever this is plugged in or unplugged, and then the load gets power again. Not a long power loss, but I recommend against using it as a power converter + backup for something that might be sensitive to this.If also cuts power momentarily when you press the button to get it to display the charge state, but in this case output power stays cut for the full time you press the button and then comes back on shortly after you release the button.Overall, well suited for my application, but I would be careful about any application that would be sensitive to momentary power losses. If you are using this as a charging device (or as a portable power bank) then the last two points should be of almost no concern to you.I have not tried to charge things with it, so check other reviews for how well that works (including the high-output modes).

Pros:- Quick Charge 3.0 supported! Otherwise 2.4A/1A.- Foldable plug allows for easy charging, and the unit charges pretty fast when plugged in.- Design is sleek, and the charging lights are good as well.- Has a bit more of juice than the competing item from Anker (6700mAh vs 5000mAh)Cons:- QC 3.0 only supported when one port is in use AND the charger is plugged into the wall. I can live with the one port at a time, but wish it supported QC 3.0 regardless of being plugged in or not.- No other input (microUSB/USB-C) to charge the bank, so if the plugs go you're SoL. This can be a big deal as plugs tend to break, so one star was taken off for that.- No carrying case included - Anker always provides a complimentary mesh carrying case.- Unit is a bit more hefty/chunky than I thought it'd be, but not that big a deal.To be quite honest - I was drawn in by the QC 3.0 and also the higher mAh. The price for the Plugornot is exactly the same as the Anker unit, and both have some things the other does not. I think if I had to do it over again, I'd go for the Anker Fusion as it has an alternative method of charging and includes a carrying case... not to say the Plugornot is bad, just if/when the prongs break, I'd rather not have a brick.

To start off, the small manual is very thorough and it’s in very readable English. The ZMI Plugornot unit was at about 25% charge when received (with mfgd date 4/2018, or 9 months ago), then plugged in to top up the charge to 100%. The unit was used to charge an iPhone to 100%, then connected to a tablet to completely discharge the unit. The ZMI Plugornot Zero device was then plugged in to the wall socket to restore full charge; it took approximately three and a half hours to completely recharge the unit. It is a 6700mAh unit with 24.3Wh, certainly below the less than 100Wh limit for a carry-on lithium-ion battery allowed for airline travel. It is made of good quality materials, not at all a lint pick up. The unit is Qualcomm Quick Charge 3.0 compatible when charging one device only, while plugged into an AC outlet; one of the two USB ports has to be left empty for 18W charging operation to occur. ZMI provides an 18 month warranty. It is approved for use at 100 to 240VAC and 50/60Hz operation. The features in this last paragraph were untested, however, it seems like a very capable unit with the caveat that it has been in my possesion only a couple of days. Three hours after having been charged, and the State of Charge button being pressed, we still get 4 out of 4 indicator lights lit.

I don't understand why more power banks don't have a wall plug built in.... This thing is so damn handy.Been using it for YEARS now and it has been 100% worth it

Update July 2020I'm raising my rating to 3 stars. The capacity is lower than advertised, but so is every other battery I've tested. Bottom line, it charges my phone multiple times and works great.------------------------------------------------------------------------------The first thing you need to know when buying a battery pack is how to look at the battery life. The mAh listed is for the 3.7V battery inside the pack. The USB output is going to be 5V (unless it's usb-c or QC) - so the mAh does not directly translate. The better metric is to look at Wh (watt hours) which takes the voltage into consideration.I hooked my ipad which was at 2% battery level and monitored the charge via a USB tester. As you can see from the pic, it delivered a consistent 2.3A but only for 17.68Wh. The charger is listed as having a capacity of 24.3Wh. The charger is only delivering 72% of its rated battery capacity.It is too bad that it does not meet advertised capacity. It feels great in your hand. I travel for work and have gone thru a lot of battery chargers, and this one feels like it will last a while. It was relatively inexpensive for what it is, I will probably just keep it.
