    Note 10+ charging voltage/current difference

    Hey my dear friends,
    On my Note 10+ charger it's written like on picture I attached.
    So I don't understand,please explain me what voltage is used when charging the phone because here I see 3 different values,and dependant on what?
    Explain me why are 3 different values shown on charger.
    I'd also like to know is this Powerbank okay to use as a portable powerbank for Note 10+ and for my tablet Samsung S5e and which ports on powerbank to use for charging devices?

    Re: charging voltage/current difference

    Hi. Good question.

    1) The shown power supply is a flexible power supply. The power adapter is able to support PD = power delivery specifications. That is, if the mating computer / phone can also support PD spec, then the 2 devices can 'hand-shake' to agree on the best choice of the power supply value (voltage & current) before starting the charging cycle.

    2) PD is based on power contracts = voltage & current pairs. It is up to the mating product (phone / tablet / computer) to request the power adapter to spit out the list of contracts and then the host computer logic will select the best choice for the charging process.

    For this reason, your power adapter offers what appears to be 2 contracts.

    3) The PPS is yet again a flexible power supply but in this case can support small steps to 'dial up' a better choice of a power rail. That is, for example can select from a starting range to a max range of voltage & current but can be incremented in steps of say 0.1 volts, etc. Some host computing devices like to use oddball values so this PPS spec was created. Again, it is the small step increments that may suit some devices the best.

    Hope this helps.

    PS: Forgot to throw out my 2-bits on the charging of your devices...

    4) Almost any charger will charge your device. The question is whether it will be slower or faster than your expected time to charge.

    Review this article on topic:

    https://www.androidauthority.com/sam...rging-1020143/

    Which states that your 10+ can charge @ 45W but only if you pair it up with a 45W charger and the mating cable is rated @ 45W.

    The cable is a 'captive cable' as known in the industry so that consumers do not mix it up.

    Best to buy the Samsung branded charger but if you have a vendor claiming the same spec then be sure to pair it up with a 45W rated cable. Then as a package, you should be able to achieve the fast charging support as designed by Samsung.

    As noted, you will be able to charge the device with other chargers but if not with a 45W output, the device will just charge slower.

      Cyberpower 1500AVR UPS repair
      by quickname
      I'd like to start out by thanking this forum for providing the info to be able to repair my 15 year old CP1500AVRLCD UPS. Here is all the info I gathered during my trouble-shooting and re-capping.

      Like clockwork, I've had to replace the SLA batteries every 4 years. It was about that time and the UPS was acting like it needed new batteries... randomly shutting off with AC present, not being able to charge fully, and poor runtime when AC was removed. So, I replaced the batteries but noticed that it was not charging properly.

      I decided to verify that the batteries were...

      Extreme High Current & Low Voltage Short Killer ??
      by DynaxSC
      Hi Folks

      I'm looking for a extreme high current short killer solution for a reasonable cost.

      I have an LGA1700 motherboard (ASUS PRIME Z790-P WiFi) where I exchanged the LGA socket already 3 times, and every time after the socket exchange I get a short of power supply lines VCORE (V variable) and VCCIN_AUX (1.8V).
      After taking off the socket, the shorts dissappear again.
      The soldermask on the socket is already partially demaged from the heat, so I have reconstructed the soldermask by manually painting the missing soldermask parts with a very small top of a...

      ASUS X54H laptop thinks it's always charging even with charger unplugged
      by flat-earther
      The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.

      Windows also shows ''Plugged in'' when charger is not connected.

      This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
      Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
      If I let battery run out and say it has 3% Windows will...
