Which charger for Samsung Galaxy Tab S12 Ultra? The power standard that matters

You are sitting in a lecture hall taking handwritten notes, or working through digital design briefs at a café, when the low-battery warning pops up mid-afternoon. With a device this large, a brief pause between tasks is all the time you have to get back to a safe percentage.

If you are trying to figure out which charger for Samsung Galaxy Tab S12 Ultra will actually refill that battery quickly, the key figure is 45W. To reach its real charging ceiling of roughly 42W, the power adapter must support the USB Power Delivery (USB PD) protocol with PPS (Programmable Power Supply). Samsung calls this mode Super Fast Charging 2.0.

Samsung does not bundle a wall adapter in the box. When you unbox the tablet, you will find the slate itself, the S Pen stylus, and a 1.0-meter USB-C to USB-C charging cable, meaning you need to provide your own plug.

Specs and charging

The key Samsung Galaxy Tab S12 Ultra specs that matter when choosing a charger:

• Battery: 11600 mAh
• Wired charging: 45 W (Super Fast Charging 2.0)
• On a standard USB PD charger: ~14 W

Can you use your existing phone or laptop power adapter?

Before purchasing another accessory, it pays to check the adapters you already own. Modern USB-C plugs work across many gadgets, but they behave very differently depending on the protocols written on their casing:

• A 45W or higher adapter with USB PD PPS: Delivers the full charging rate of around 42W. If you bought an official 45W Samsung plug for an older model like the Tab S11 Ultra, it will run at peak performance here too.
• A standard USB PD charger without PPS (such as many 20W to 65W phone or laptop bricks): Drops back to a fixed-voltage profile. Independent predecessor measurements show this path tops out at around 14W. It will charge your tablet reliably, but noticeably slower.
• A standard charger without any fast charging protocol: Falls back to basic USB power, trickling in at only 5W to 10W. On an 11,600 mAh cell, this can take many hours.

To see what your current plug can do, look at the small print on its plastic housing. You want to spot the letters "PPS" alongside a power rating of at least 45W.

Fun fact: Despite housing a massive 11,600 mAh battery beneath a 14.6-inch display, the tablet measures just 5.1 mm in thickness and weighs 692 grams.

Charging an 11,600 mAh battery: what does 95 minutes look like daily?

Refilling an 11,600 mAh battery requires serious throughput. According to Samsung, charging from 0 to 100% with a 45W charger takes about 95 minutes, and Expert Reviews also reports about 95 minutes. In the first independent post-launch test, Trusted Reviews recorded about 40% after 30 minutes and a full charge in about 90 minutes.

Measurements on predecessor hardware with the exact same 45W limit showed that 45W to 140W PPS chargers delivered an active rate of around 40W to 41W. That consistency means plugging in for 30 minutes during a lunch break puts enough usable runtime back into the cell for several hours of intensive creative tasks or media viewing.

Because the Tab S12 Ultra shares the same battery capacity and charging parameters as the Tab S11 Ultra, any power brick that worked at top speed for the previous generation works just as effectively here.

Selecting the right power brick for your desk and bag

If you need to buy a new adapter, picking one comes down to how many devices you want to plug in at once. The official Samsung 45W Power Adapter EP-T4511 provides the most straightforward match, delivering about 42W directly to the tablet without any setup guesswork.

For a dedicated single-port brick on a budget, the Google 45W USB-C Charger hits that exact same ~42W peak while keeping costs lower. It gives you full-speed refueling in a tidy, travel-friendly footprint.

If your daily bag holds both your tablet and a work machine, a multi-port option makes more sense. The UGREEN Nexode 65W and the Anker 735 (Nano II 65W) both support PPS, reach the tablet's ~42W limit, and feature three ports so you can power a laptop or top up your phone from the same wall outlet.

Fun fact: In local video playback testing conducted by Expert Reviews, the Tab S12 Ultra managed 19 hours and 44 minutes of runtime, outlasting the Tab S11 Ultra by more than 2.5 hours.

Common power traps to avoid with the Tab S12 Ultra

The biggest trap is assuming higher wattage speeds up charging. Buying a 100W or 140W power brick will not make the tablet fill up faster than a 45W unit, because internal controllers strictly limit incoming power to roughly 42W.

Another common mistake is relying on raw wattage labels without checking for PPS. A 65W laptop charger that lacks PPS support drops down to the standard USB PD baseline, pulling only around 14W and roughly tripling your wait time.

Multi-port chargers also require attention. When you plug a second cable into a 65W brick to power your phone at the same time, the adapter splits its available wattage, which can drop the primary port below the threshold needed for full 45W charging.

You also do not need to replace the cable in the box. Predecessor power tests showed that a standard 3A cable delivered 40.9W compared to 41.4W on an expensive 5A e-marked cable, proving the included 1.0-meter 3A cable handles full-speed charging without issue.

Galaxy Tab S12 Ultra power and charging questions answered

Which charger for Samsung Galaxy Tab S12 Ultra gives the fastest speed?

You need a charger that supports USB Power Delivery PPS with at least 45W of output. This enables Super Fast Charging 2.0, pulling the tablet's real peak of around 42W and completing a full charge in roughly 95 minutes.

Is a wall charger included in the box?

No, Samsung does not include a wall adapter in the box. Inside, you get the tablet, a 1.0-meter USB-C to USB-C cable rated for 3A, and the S Pen stylus.

Can I safely charge this tablet with a 65W or 100W laptop adapter?

Yes, higher-wattage USB PD chargers are safe because modern devices negotiate their power intake automatically. However, it will not charge any faster than a 45W PPS plug, as the tablet caps its input around 42W.

Will my phone charger work properly?

It will charge the tablet, but the speed depends entirely on its specifications. If it is a basic phone adapter without fast charging, power input drops to 5W to 10W, while standard USB PD plugs without PPS sit around 14W.

Is the S Pen included with the Galaxy Tab S12 Ultra?

Yes. The box contains a hexagonal S Pen with the same IP68 rating as the tablet. Samsung says it is ready to use straight out of the box, so there is no need to buy one separately.
