    Great for it's intended Purpose, EVEN BETTER for a Electronics Engineer or Maker!!!!
  

*by P***K on Reviewed in the United States on February 28, 2018*

Okay, it looks like a tumor! Well it is NOT a tumor, it is some pretty amazing hardware serving a very simple purpose, but here is the best part: it is 15 dollars. So I cannot find ANYONE ELSE who has torn this guy down, so I will tell you my experance and what is inside.3 Boards not counting the 3S Balancing board on the 4AH 3S Pack. 11.1v-12.6v 3S with Balacing and Protection. (This is itself a module in shrink wrap.AC to RAIL Voltage Board (This board takes the AC power from the Wall and makes it so the Transfer board can use it to charge the battery, and drive the DC to AC Power Invert-er Board.Transfer board, this board has some circuitry on it, but is a housing for the bridge rectifier, and connects everything via traces, wires, and ICs. It is less packed than the AC-DC or DC-AC boards.Finally the Power Inverter very simlar to what you have in a car/truck/van. Simple Transformer that takes DC and makes 120VAC 45W-65W to power the Apple Adapter.So YES, it takes AC, makes DC, then Takes DC and Makes AC again. So in a way, it is very silly way to create a backup battery, but in another way, it is a goldmine of DIY parts waiting for you to jump in. You can also power anything with the 2 pin AC plug, not just the MacBook. I used mine as a UPS for my Gateway Router/AP Controller and it worked great until I couldn't take it anymore and had to find out what is inside. To be clear, it still works, I just dumped the tumor case, and turned it into a combination SMPS that also makes 19.5v 4A + USB in addition to the AC this unit makes stock.  65watts isn't much for AC appliances, but for things that take AC and make DC like iPhone USB Chargers, it is awesome.So I am buying another and making an instructable on it since no one else has. For 15 bucks this is WAY more than worth it, but be careful it is more than likely cheap because it didn't sell well and it is being liquidated. Try and be fair and not buy them all or ruin a good thing.So before you even think about opening this thing up, the Wires from the AC board to the AC connectors are NOT soldered. They have a very strange unsafe Paste that connects them NOT a solder weld. It comes off very easily and could injure you, in my opinion all the more reason to fix that factory oversight and do it right. Again electronics are dangerous, but if your a DIY guy, this is the one to grab.This works almost identical to a VERY expensive Double Conversion commercial UPS for again 15 dollars, not 600. Way different scope of power, but again, it is interestingWhen working with electronics do not open anything you do not understand, or cannot evaluation the danger of. This unit has constant AC in 2 forms as well as a Lithium Battery. Be Safe and if you have doubts, don't do it.

    See Pic. Does not charge THIS 13" 60W Macbook Pro. So, what model does it in fact charge?
  

*by B***E on Reviewed in the United States on September 22, 2018*

as you can see in my pic, the battery is all charged up, I plugged it into my 60w mag safe charter and powered the baby right up - so far so good.  But then when I plugged the now fully charged battery up to my "as advertised" right in the title of the item, 13" Macbook pro with 60w adapter - NO JUICE, NO POWER, NOTHING.  So, don't waste your money, these guys don't know what hardware or software this is really compatible with.  You might get lucky and it works and then you might upgrade your software or something and it won't.

    Nice little charger
  

*by P***E on Reviewed in the United States on August 24, 2018*

I just got it so can’t really review the battery life but I can review the seller it came from.  This thing was 100% used the box looked like it came from a flood.  It also smelled of women’s perfume so heavily my kids thought someone was at our house.  The plastic sticker was on it but clearly someone had saved it and put it back on.  I tested the chugplug and it does work I have a MacBook Air 11” and it shows as plugged in but not charging which is fine by me as long as in a pinch I can get power.  The unit is very light weight and fits nicely in my book bag.  Originally the price was 150 so for 15 bucks you can’t complain.**UPDATE**Got a new apple charger and battery is now charging when using the chugplug, next update will be in a few months to see how the battery lasts on the chugplug.
