Phones stopped shipping with a charger block years ago, and the one that came with your last phone is probably 12W or less. A modern USB-C Power Delivery block charges an iPhone or Pixel to 50% in about half an hour, a 45W block does the same for a Galaxy S-series, and a 65W block charges a laptop. The five below are the blocks owners buy most and rate highest, from a single 20W plug to a three-port laptop charger.
We picked them from our catalog by owner rating (4.4 stars or better) and review count, then checked wattage, port count, plug design and safety certification. We have not bench-tested every block ourselves; the verdicts lean on spec sheets and what owners report after months of daily use. Prices are not printed because they change daily; every button opens the live Amazon page.
How we picked
- USB-C Power Delivery (PD 3.0), the standard every current phone, tablet and laptop charges with. Old USB-A “quick charge” blocks were skipped.
- The right wattage for the job. 20W is full speed for iPhones and most Androids; 45W for Samsung Super Fast Charging 2.0 and iPads; 65W for laptops.
- Compact and foldable where it matters. Travel blocks should fold their prongs and not block the second outlet.
- Safety: over-current, over-voltage and temperature protection on every pick, and UL or ETL listing where the seller states it.
- Owner ratings of 4.4 stars or better from the accessories catalog, favoring blocks with thousands of reviews.
The picks
Anker Phone Charger, 20W USB C Charger Block, Type C Charger Fast Charging
This is the charger block most people should buy and never think about again. Anker’s 20W USB-C PD block charges an iPhone 15 or 16 to 50% in about 30 minutes, which is the ceiling Apple allows, and it does the same for a Pixel or a mid-range Samsung. It is tiny, cool to the touch, UL listed, and backed by a two-year warranty. More than 31,000 owners have rated it, and the complaints are the two things it does not have: a second port and folding prongs. Pair it with any USB-C cable you already own.
- 20W is the maximum an iPhone accepts, so this is full speed
- Over 31,000 owner reviews at 4.6 stars
- Small enough to disappear in a pocket
- Anker 24-month warranty
- One port only
- Prongs do not fold
- No cable in the box
Anker 65W Max 3-Port USB C Charger Block, Compact Foldable Phone Charger
The 65W 3-port is the one block to pack for a trip. Alone, the top USB-C port pushes 65W, enough for a MacBook Air, a Dell XPS 13 or any laptop that charges over USB-C. Add a phone on the second USB-C port and the power splits 45W and 20W, which still charges both at full speed. It uses gallium nitride (GaN) parts, so it is about half the size of a laptop brick, and the prongs fold flat. Owners rate it 4.7 stars across 22,000 reviews; the only recurring note is that the third port, USB-A, is for a watch or earbuds, not a tablet.
- Charges a 13 or 14-inch laptop, a phone and earbuds from one plug
- GaN design: half the size of the brick that came with the laptop
- Foldable prongs for travel
- 22,000 owners at 4.7 stars
- 65W splits to 45W + 20W when two ports are used
- The USB-A port is slow (12W)
- Costs about three 20W blocks
45W USB C Charger Block 4Pack Fast Charging Power Block for Home & Office
If your household has a Samsung flagship, an iPad or a Nintendo Switch, 20W is not enough: Samsung Super Fast Charging 2.0 wants 45W with PPS, and this four-pack delivers exactly that at a per-block price that brand-name 45W chargers cannot touch. Each block has one USB-C port, the usual protections and a 4.7-star rating from 5,500 owners who mostly bought it to stop moving one charger between rooms. It will also charge a MacBook Air, slowly. The trade-off is size and fixed prongs, so keep it at home and travel with the Anker.
- Four 45W blocks for the price of one brand-name 45W charger
- 45W with PPS is the full speed for Samsung Galaxy S and iPad Pro
- One for each room, car bag and office
- 4.7 stars from 5,500 owners
- Larger than a 20W block
- No folding prongs
- Lesser-known brand, shorter warranty
CXX Charger for iPhone 20W Fast Charging [MFi Certified, 2-Pack] USB-C PD Block & 6FT Cable Compatible with iPhone 14/13/12/11/Pro/Plus/Max/Mini/SE, iPad & More [Black]
![CXX Charger for iPhone 20W Fast Charging [MFi Certified, 2-Pack] USB-C PD Block & 6FT Cable Compatible with iPhone 14/13/12/11/Pro/Plus/Max/Mini/SE, iPad & More [Black]](https://dobestdeals-img-2.pages.dev/cxx-charger-for-iphone-20w-fast-charging-mfi-certified.webp)
For anyone still on an iPhone 14 or earlier, this kit solves the whole problem in one order: two 20W blocks and two 6-foot Lightning cables that carry Apple’s MFi certification, so iOS never nags. Thirty-two thousand owners have bought it as the bedside-and-desk pair. The rating is a shade lower than Anker because a small share of cables wore at the connector after a year; at this price that is the expected trade. iPhone 15 and 16 owners should skip it and buy the Anker 20W plus a USB-C to USB-C cable.
- Two blocks and two 6-foot MFi-certified Lightning cables in one box
- MFi means no "accessory not supported" warnings on older iPhones
- 32,000 owner reviews at 4.4 stars
- Long cables reach a nightstand from a floor outlet
- Lightning cables: iPhone 15 and newer need USB-C to USB-C instead
- Cable sheath is standard plastic, not braided
- 4.4 stars reflects a few early failures
[3 Pack] 20W USB C Charger Block Fast Type C Dual Ports Power Adapter
![[3 Pack] 20W USB C Charger Block Fast Type C Dual Ports Power Adapter](https://dobestdeals-img-9.pages.dev/3-pack-20w-usb-c-charger-block-fast-type-c-dual-ports-power.webp)
This is the three-pack to scatter around the house. Each block carries a 20W USB-C port and a USB-A port, which means a new phone and an old pair of earbuds charge from the same outlet, and three of them cost less than a single branded charger. Ten thousand owners rate the set 4.6 stars. Use one port at a time for full speed; with both ports in use the 20W is shared.
- Three dual-port blocks for less than one brand-name 20W charger
- USB-C plus USB-A on each, so old cables still work
- 10,000 owners at 4.6 stars
- Good for guest rooms, kitchens and the car bag
- 20W is shared when both ports are used
- No PPS, so Samsung flagships charge at 15-18W
- Plastic feels lighter than Anker

How many watts do you actually need?
- iPhone (any model): 20W is the maximum the phone draws. A 30W or 65W block does not charge it faster.
- Pixel and most Android phones: 20-30W.
- Samsung Galaxy S and Note: 45W with PPS for Super Fast Charging 2.0; a 20W block works but takes almost twice as long.
- iPad and Nintendo Switch: 30-45W.
- 13-14-inch laptops (MacBook Air, XPS 13, ThinkPad X1): 60-65W.
- 15-16-inch and gaming laptops: 100W or the laptop’s own brick. See our USB-C laptop chargers guide.
A bigger block never hurts a smaller device; USB-C PD negotiates the voltage the device asks for. The only thing a 20W block cannot do is charge a laptop at full speed.
GaN, PPS and MFi: the three labels that matter
GaN (gallium nitride) chargers run cooler and smaller than silicon ones, which is why the Anker 65W is the size of an old 20W block. PPS (Programmable Power Supply) is the part of the USB-C standard Samsung uses for its 45W charging; the iGENJUN pack supports it, the budget 20W packs do not. MFi (Made for iPhone) applies to cables, not blocks: an MFi Lightning cable like the ones in the CXX kit will never trigger the “accessory may not be supported” warning. Blocks only need USB-C PD, and every pick here has it.
If one outlet has to feed a whole desk, a power strip with USB ports or a charging station for multiple devices replaces a drawer of blocks; a USB-C dock does the same for a laptop. For the cable side, a USB-C to 3.5 mm adapter is the other dongle most phones now need.
Will a 65W charger damage my phone?
No. USB-C Power Delivery is negotiated: the phone asks for 20W and the block supplies 20W. A higher-wattage block only matters for devices that can draw more, like laptops and tablets.
Why does my Samsung charge slowly on a 20W Anker block?
Samsung Super Fast Charging 2.0 needs 45W with PPS. On a plain 20W PD block a Galaxy S24 charges at about 15-18W, which still fills it in under 90 minutes but is slower than the box promises. The iGENJUN 45W pack supports PPS.
Do I need a special cable?
For 20-45W, any USB-C to USB-C or USB-C to Lightning cable works. For 65W and above the cable should be rated 60W or 100W (most are); a cheap thin cable can limit a laptop to 30W. For older iPhones, use an MFi-certified Lightning cable.
Are the no-name multipacks safe?
The ones here have thousands of reviews and the standard over-current, over-voltage and thermal protections. The practical difference from Anker is warranty length and build quality, not safety. For a charger that lives on a nightstand next to a bed, we still prefer the UL-listed Anker.
