You’ve heard us talk about PD Tech, various types of batteries, and how to maximize your battery life. But what about iSmart charging technology, which keeps you protected while optimizing your charging potential?
We’ve launched a number of products with this tech, including our new PC105 wall charger. Read on to learn more about it!
Smart Current
Batteries have chips that allow them to regulate the amount of current they receive from USB charging devices. They do this to optimize charging speed and prevent damage to the battery from overcharging, as can happen when you use a constant current charger. Set at approximately 10% of the maximum battery rating, your device would take a long time to charge and the battery could overheat.
In other words, which charger you use matters. iSmart charging tech can adjust the charge current and charge time accordingly to the battery specifications, which can help extend battery life. It also supports 2.4A output, which is the maximum need for most popular phones and tablets.

Smart Voltage
iSmart Chargers correct charging irregularities caused by older ports and cables. All USB cables carry a standardised voltage of 5V, which can be reduced over time as cables become older and damage. Indeed, a dusty USB ports can reduce a product’s charging voltage to under 5V, and so prolong charging time. Then there is the issue that the same charger/USB voltage combo will charge your Macbook at one speed and your iPhone at another.
Charging your Macbook with the same charger you use for your cell will cause different results and different charging times – using an iSmart fixed or portable charger fixes this issue. Throw away all other chargers, we’ve got your back!

Smart Distribution
We’ve already said to throw away your charger – but what if you have multiple devices?
Fear not. An iSmart 2.0 charger optimizes its output to both devices that are plugged in. You get an even charge distribution, so your devices power up quickly and efficiently.
What’s more, you can charge any two devices together. If you have a Macbook and a Samsung (…there can’t be that many of you out there?) then you don’t have to think about which device you’re charging where.

Smart Protection
There are 10 comprehensive, all-encompassing types of protection available to you through iSmart. These include:

If you’re looking for an iSmart charging smart device then RAVPower have a few options for you. For a wall charger, we recommend our new PC105 charger, and of course model PB080 for a portable charger. Or if you’re a person who wants options, why not try both!
I use the RAVPower 4-Port USB 40W iSmart Wall Charger and I have to say, it is awesome. I am not sure the 2 port charger is quite enough these days as we have an ever-growing number of devices. I love the iSmart technology, it is so fast. Everyone should have one of these at home or at work.
That’s great to hear, Samuel. We’re so glad you love your iSmart charger!
PowerDelivery, QuickCharge and iSmart
1. Which of these use a ‘2-way protocol’ between charger and device to negotiate
charging ?
2. When there is a mismatch and/or no-protocol at opposite ends of the charging cable,
how is power, voltage, amperage resolved ?
3. Why are there no USB PD/3.0 cables with fixed USB-C head at one end and
magnetically attachable USB-A, USB-C, USB-micro and lightning (Apple) heads for the
opposite end (or both ends with 4 interchangeable heads) ?
Thanks in advance.

Hi, please contact support@ravpower.com to answer your query. Thanks!
I have an RP-PC-006-EU with two USB outputs
Output 1 (Qualcomm quickcharge ?) with a broad range of voltages indicated 3.6-6.5V … 9-12V
Output 2 (iSmart) 5V
What is actually the difference between these two.
What should I use for iPad, iPhone, LED lamp, other usb devices?
Hi there,
Output 1 is a QC 3.0 port which can fast charge QC compatible devices. But for non QC compatible devices, it is just able to deliver a normal charge (5V/2.4Amax). If your device supports Qualcomm® Quick Charge, then please use this port for a more efficient charge. Both ports are also suitable for non QC devices. Hope this helps!
My router requires 12V 1 A. I use the QC 3.0 port and it works fine. Looks as if the output voltage is adaptive
Your mileage may vary.
Hi,
What are the USB protocol/cable (2.0, 3.x, 4.0, etc.) and connector (type-A, mini-B, etc.) combinations compatible with iSmart ?
Regards,
Hi, iSmart is compatible with the normal USB protocol and type-A connector.
Hi ، I have a RavPower power bank model : RB194 supermini 18 watt (10000 mAh)
with 2 port (PD & QC)
when i charge my an I phone XS with PD port become super hot !!
can i use QC to charge my an iphone ?Thank you ravpower
Hi could you please write an email and include your model number and the issue you described to support@ravpower.com. Our support team will be happy to help.
I have ravpower mini when i charge my phone which support qualcom QC the green led of power bank which indicates fast charging turns off when the phone reaches 80% of charging, is that normal ? Why the green led not stay on till 100% of mobile charging?
Hi Islam, for RP-PB194, this is decided by the mobile phone you are charging.
To protect battery life and prevent overheating, lots of devices these days will accept fast charging when the battery’s low, but when it gets mostly full they slow down the rate they’re putting power into the battery.
(Details seem to vary widely, but the behaviour you described is pretty typical for things where your charger, cable, and device are all compatible with the standard you’re using, and the green light tells you it really was able to do more than just the 5V/1A things fall back to when they’re not happy.)
Hi! Do this have too with eu plug, and is this fast charger or not?
Hi, which charger model would you like to know about EU availability?
