Samsung 45W Charger on Flipkart for Rs 2,299 — Here Is What Nobody Tells You
Let me tell you something that irritates me about Samsung. They sell you a phone for Rs 1,30,000 — like the Galaxy S24 Ultra — and then they don't even put a charger in the box. You get a USB-C cable and that's it. No charger. Samsung says it's for the environment, which sure, fine, I get it. But then they sell you the charger separately for Rs 3,499. That feels like a bit of a racket, honestly. The good news? Flipkart currently has the Samsung 45W Super Fast Charger at Rs 2,299 — a 34% discount — which makes this a much easier pill to swallow.
I've been using this charger for about five months now with my Galaxy S24 Ultra, and I've some strong opinions. Some good, some not so great. If you're a Samsung user thinking about finally upgrading from that old 15W or 25W charger, or if you just bought a new Galaxy phone and need a charger because Samsung didn't bother giving you one, keep reading.
Why 45W Matters — And When It Does Not
First, let me clear up some confusion that I see constantly in comment sections on Flipkart and Amazon. Not every Samsung phone supports 45W charging. In fact, most Samsung phones do NOT. The 45W Super Fast Charging 2.0 is limited to specific flagship models — the Galaxy S24 Ultra, S23 Ultra, S22 Ultra, and the Galaxy Tab S9 series. If you have a Galaxy S24 or S24+, those max out at 25W. The Galaxy A-series phones? Mostly 25W or even 15W.
So before you rush to buy this charger, check what your phone actually supports. If your phone only supports 25W, buying a 45W charger won't make it charge faster. It will just charge at 25W because the phone controls the maximum charging speed, not the charger. The charger can offer up to 45W, but the phone takes only what it's designed to handle.
That said, there's an argument for buying the 45W charger even if your current phone only supports 25W. Future-proofing. If you plan to upgrade to a phone that supports 45W in the next year or two, you already have the right charger ready. And the 45W charger still charges 25W phones at full speed — it's backward compatible. So you aren't losing anything.
The Actual Charging Experience
Alright, let me talk about what it's actually like to use this thing. With my Galaxy S24 Ultra, going from 0% to 65% takes about 30 minutes. That is really impressive. I've timed this multiple times because I'm that kind of person who obsesses over numbers. From 0% to 100% is about 56-60 minutes, though the last 20% slows down significantly because Samsung's battery management system reduces speed to protect battery health.
Here's a real-life scenario. I was getting ready for an early morning flight out of Bangalore airport — Kempegowda International, which is like an hour from the city centre if traffic is good. My phone was at 12% because I forgot to charge it overnight. Panic mode. I plugged in the 45W charger while I was showering and getting dressed. Twenty minutes later, phone was at 52%. That was enough to get me through the ride to the airport, the check-in process, and the flight. That kind of speed honestly saves you in real situations.
Compare this to the old 15W charger that used to come with Samsung phones. From 0 to 50% with a 15W charger takes well over an hour. The difference is night and day. Even compared to the 25W charger, the 45W is noticeably faster in that first 0-60% range where you need juice the most.
Does It Get Hot?
This is a question I get asked a lot, and the honest answer is — yes, a little. During 45W charging, especially in the first 30 minutes when the phone is charging most aggressively, both the phone and the charger get warm. Not alarmingly hot, not "I'm worried this is going to catch fire" hot, but noticeably warm to the touch. The charger itself has Samsung's multi-layer protection built in — overcurrent protection, overvoltage protection, temperature control, all the safety stuff. So I've never felt unsafe using it.
But in Indian summers, particularly if you live in places like Hyderabad or Jaipur where room temperatures hit 40+ degrees, the warming up is more noticeable. I'd recommend not charging your phone under a pillow or in a closed drawer during summer. Keep it in open air for proper heat dissipation. This is good practice for any fast charger honestly, not just this one.
What Is in the Box
This is where Samsung actually does something right compared to Apple. The Samsung 45W charger comes with a USB-C to USB-C cable in the box. It's a 1.8 metre cable, which is a good length. Apple charges you Rs 3,499 for a MagSafe charger and doesn't include a power adapter. Samsung at least gives you the cable. Small win, but I will take it.
The charger itself has a compact, square-ish design with a matte black finish. It has foldable prongs, which is fantastic for travel. The prongs fold flat against the body of the charger, so it doesn't snag on anything in your bag. The build quality feels solid — there's no flex or creaking when you squeeze it, and the USB-C port is snug. Overall it feels like a proper first-party accessory, not some cheap add-on.
Weight is about 72 grams, which is reasonable. You barely notice it in a bag or even a jeans pocket. The single USB-C port is the only output — no USB-A, no second port. If you need to charge two devices simultaneously, you will need a different charger. That's a limitation worth noting, especially for people who charge their phone and earbuds at the same time.
Compatibility Beyond Samsung
Here's something interesting that Samsung doesn't advertise very loudly. The 45W charger uses USB Power Delivery 3.0 with PPS (Programmable Power Supply). This means it can fast-charge non-Samsung devices too. I tested it with my friend's iPhone 15 Pro and it charged at about 27W, which is essentially the iPhone's maximum wired charging speed. It also fast-charges Pixel phones, OnePlus phones (though not at full VOOC/Warp speed), and even some laptops at lower wattages.
So while it is marketed as a Samsung charger, it's actually a pretty versatile USB PD charger that works well with most modern USB-C devices. That makes the Rs 2,299 price on Flipkart even more attractive because you're essentially buying a multi-device charger.
I've been using it as my travel charger for all devices — Samsung phone, iPad mini, and even my Pixel Buds. It handles everything. The only device it struggles with is laptops that need more than 45W, like a MacBook Pro 14 which wants 67W or higher. For something like a MacBook Air or a Chromebook though, 45W is perfectly adequate.
Flipkart Bank Offers and Getting the Best Price
At Rs 2,299, this is already a good deal. But Flipkart has some additional offers running. The Flipkart Axis Bank credit card gives you 5% unlimited cashback, which brings the effective price down to about Rs 2,184. That's genuinely good for an official Samsung 45W charger. HDFC Bank also runs periodic instant discount offers on Flipkart — usually Rs 100-200 off on electronics purchases above Rs 1,500.
If you have Flipkart SuperCoins, you can convert them to discount coupons and apply those too. I'd about 500 SuperCoins lying around from previous purchases, which gave me an extra Rs 250 off. Between the sale price and the bank offers, I ended up paying around Rs 2,000 for this charger, which I think is great value.
Pro tip for those in cities with Croma or Reliance Digital stores — sometimes these offline retailers match Flipkart prices during festive seasons like Diwali, Dussehra, or even Independence Day sales. Plus you can physically see and hold the product before buying. But for this particular deal, Flipkart's Rs 2,299 price is hard to beat and I'd just order it online.
Third-Party 45W Chargers vs Samsung Official
I know what some of you're thinking. "Why should I spend Rs 2,299 when I can buy a 45W charger from Baseus or Ambrane for Rs 1,000-1,500?" Fair question. And honestly, some third-party chargers are perfectly fine. Brands like Anker, Baseus, and even Portronics make good 45W USB PD chargers that will fast-charge your Samsung phone.
But here's the catch. Samsung's Super Fast Charging 2.0 protocol has some Samsung-specific handshake requirements. Not all third-party chargers trigger the "Super Fast Charging 2.0" indicator on your phone. Some might fall back to regular "Fast Charging" at 15W or "Super Fast Charging" at 25W. The Samsung official charger always triggers the full 45W Super Fast Charging 2.0. If you're paying a premium for a 45W-capable phone, you want it to actually charge at 45W consistently.
I've tested this myself. Bought an Ambrane 45W PD charger from Amazon for about Rs 1,100. It charged my S24 Ultra at "Super Fast Charging" — which is the 25W tier, not the 45W tier. The Ambrane charger worked fine, charged the phone fast enough, but it wasn't delivering the full 45W that the Samsung charger provides. Some third-party chargers do trigger 45W, particularly ones from Anker and Spigen that explicitly list PPS support. But if you do not want to gamble, the Samsung official charger is the guaranteed choice.
Battery Health Concerns — The Elephant in the Room
Every time I talk about fast charging, someone in the comments asks "but does 45W charging ruin your battery?" It's a legitimate concern. Fast charging does generate more heat, and heat is the enemy of lithium-ion batteries. Samsung has addressed this with their Adaptive Charging feature that learns your charging patterns and adjusts speed accordingly. If you charge overnight, the phone slows down to protect the battery.
After five months of almost daily 45W charging, my Galaxy S24 Ultra's battery health is still at 97% (you can check this in Settings > Battery > Battery Health). That's pretty normal degradation. For reference, a friend who exclusively uses the 25W charger reports 98% after the same period. The difference is marginal. Samsung's battery management system is quite good at protecting the battery regardless of charging speed.
My advice? Use 45W when you need speed — mornings before work, quick top-ups before heading out. Use slower charging overnight. Samsung's phone settings have options for this. You can even set a charging limit to 85% to further preserve battery longevity. I've mine set to 85% for overnight charging and 100% only when I know I'll need the full battery for a long day out.
Who Should Buy This Charger?
If you own a Samsung Galaxy S22 Ultra or newer, or a Galaxy Tab S9 series tablet, this charger is practically a required purchase. Samsung does not include it in the box, and the charging speed difference compared to the 15W adapter you might have from an older phone is massive. At Rs 2,299 on Flipkart with additional bank offers available, the price is reasonable for what you get.
If you own a Samsung phone that only supports 25W, this charger still works perfectly — it just won't give you the extra speed. You might be better off getting the Samsung 25W charger which is usually available for around Rs 1,200-1,500. But if you think you will upgrade to a 45W-compatible phone in the near future, buying the 45W charger now saves you from buying another charger later.
For non-Samsung users, this is still a decent USB PD 3.0 charger with PPS support. It fast-charges iPhones, Pixels, and most modern USB-C devices. But frankly, you can find better multi-port options from Anker or Baseus for similar prices that offer more versatility. The Samsung charger's single port is its biggest limitation if you aren't specifically in the Samsung world.
