Xtar PB2S Review (Battery Charger and Powerbank) 

You mean the red LED model. But yeah, the negative to this product is the magnetic cover. That was a huge mistake.

@@Resist4 that's why I put a hair band on it..

@@generaldistrust if they had thought the design out properly, you wouldn't need a hair band on it.

@@Resist4 think of what was if there were 4 points of little powerful neodymium magnets.. how that'd be like.. basically, FYI, I have it and I don't use the band around it because I barely got to travel with it on me, I just put it indoors most of the time while I'm out with one of the mods anyways

@@generaldistrust shouldn't of used any magnets, should have snapped in place.

Illumn, check the description for a link

@@LiquidRetro ANYTHING BETTER FOR MID 2021? OR IS THIS PB2S IT? IF SO LOOKING FOR SOME 21700 WITH NO PROTECTION AT A DECENT PRICE THAT ARE HQ WE LOVE YOUR VIDS HERE AT THE US SPACE FORCE )

For 21700 unprotected this is still a good option

​@@LiquidRetro OK GOT ONE AND 4 TOTAL 21700s (50E) ANYWAY TO MAKE IT CHARGE SLOWER ( EVEN THOUGH 21700s CAN HANDLE A BUNCH OF CURRENT) SO THE BATTERIES LAST LONGER? TY SEMPER FI GUNNY

NOT IN LOVE WITH THE SOFT RUBBER, ITS GONNA WEAR FAST AND OR MELT...WISH BUTTON WAS LESS EASY TO USE ( WILL TURN ON MAYBE IN OUR PACKS)

This was aong time ago, so take this with a grain of salt, but I measured it from the USB side and then compared to the batteries capacity. They were legit and healthy cells so the ratings were pretty accurate.

​@@LiquidRetro i have no doubts on the USB side. but you cannot compare the battery rating (charging capacity) to the usb output capacity. you need to directly measure the power output of the battery, this is because there are things happening in the battery including voltage drop due to load & "discharging capacity" . note that discharging capacity is dependent to output current, the higher the current, the more the charge in the rated capacity will be wasted... i hope you get me coz i too did this mistake ahahaha. (edit: you can try this with your xtar vc4s charger. discharge a battery to 3V then charge it to 4.2V you will see that its the same as the rated capacity. Now try the grading mode and you will see that its less than the rated capacity. i think xtar is discharging it at 500mA, that means @500mA you will have that bat capacity. now think about 2A, the capacity will even be lower...)

I believe it will do 12v PD, it's listed in the specs, not sure how I force that. The advantage of c to c is you can use the other port to charge a device at the same time

@@LiquidRetro Thank you very much, Jon.

@@LiquidRetro Will it provide more conversion efficiency than the Type-c to type-c?

It should be tight but fit

I'd like a water resistant one too, no clue myself if you find one let me know

Overheating or just more heat due to the increased current?

The trustfire batteries are a fire hazard to begin with. I would start with the new Samsung batteries first.

@@LiquidRetro so apparently those old 18650 batteries were the issue. These new 21700 batteries work fine. Question....the PBS2 is a battery charger and power bank, what's the difference?

Dan A battery charger will replenish/recharge batteries that need to be recharged (when it is connected to a power source). A power bank will use the replenished/recharged batteries inside it to transfer the stored energy to a connected device that needs recharging, such as a mobile phone, tablet, flashlight with a built-in recharging port, etc.

@@allemander I finally understood. Thanks!

@@LiquidRetro I believe that it's ANY 18650 with "FIRE" in the name.. Of course - anything that is supposedly with a rating of higher than 3500 is also suspect.. Any 18650 on Amazon and or EBay also as well. The list goes on and on and on.. Buyer beware..

Illumn is my favorite source in the USA for batteries.

@@LiquidRetro what about the 18650 Battery Store?

@@Resist4 should be a good place. I have ordered from them once.

my zanflare charger does that when using powerbank feature too. exact same behavior

That would be because it does not charge to full 4.2v, and does not discharge below 3v. Instead, it charges barely above 4v, and discharges only down to 3.3v. They set it like that to stay "safe". Not to overcharge a cell and not to over discharge a cell. By doing so they are wasting over 40% of factual cell capacity.
