EcoFlow has packed nearly the full airline limit into the RAPID Pro power bank: 27,650mAh, or 99.54Wh, just under the 100Wh line for carry-on batteries. According to EcoFlow’s U.S. product page, it can send out 300W across four USB-C outputs. One of those is a 140W cable that retracts into the body. EcoFlow also says the bank refills to 80% in 20 minutes on its 320W charging station. On Oct. 17, 2026, EcoFlow listed it at $175.99, down from a $199 regular price.

How the 300W gets shared
A power bank’s total output is a shared budget. Here’s how the RAPID Pro’s ports line up against common devices:
| Port | Max | Good match |
|---|---|---|
| Built-in cable (C1) | 140W | 16-inch laptop on fast charge, Starlink Mini (needs a 100W, 20V/5A supply) |
| USB-C port (C2) | 140W | A second laptop, or a gaming handheld |
| USB-C (C3) | 65W | Tablet, 13-inch laptop, camera battery charger |
| USB-C (C4) | 65W | Phone, earbuds, watch |
Add 140 + 140 + 65 + 65 and you get 410W, which is more than the 300W total. With all four ports busy, at least one port gets less than its maximum. In practice, phones and earbuds draw far less than 65W, so two laptops plus two small devices usually fit within the 300W budget. EcoFlow’s FAQ says power is split according to what each connected device asks for.
How many charges? (estimates)
A power bank never delivers its full rated watt-hours. EcoFlow’s FAQ notes losses in “the battery and the conversion circuit.” I assume about 80% gets to your devices, which works out to roughly 80Wh. Battery sizes below are typical round numbers, so check your own device’s watt-hour rating.
| Device | Typical battery | Full charges (estimate) |
|---|---|---|
| Large smartphone | ~17Wh | ~4.5 |
| Tablet (11-inch) | ~30Wh | ~2.5 |
| 13-inch laptop | ~50Wh | ~1.5 |
| 16-inch laptop | ~100Wh | ~0.8 |
| Gaming handheld | ~40–50Wh | ~1.6–2 |
RAPID Pro and a Starlink Mini
Starlink’s spec sheet asks for a USB PD supply of at least 100W (20V/5A) when you use its USB-C cable, and lists the Mini’s average draw at 25–40W. The RAPID Pro’s 140W ports support PD 3.1, so on paper they meet that requirement. At about 80Wh delivered:
| Mini average draw | Runtime (estimate) |
|---|---|
| 25W | ~3.2 h |
| 30W | ~2.7 h |
| 40W | ~2 h |
That’s enough for a work session or a couple of video calls from a trailhead. For a full day, you’d want a power station or a second bank. My XTAR MP158 Starlink Mini test and our Starlink Mini off-grid power guide cover longer setups. If you’d rather use your own cable, the STARGEAR retractable USB-C cable I reviewed is rated for 140W PD.
Recharging the bank
EcoFlow quotes 320W of input and 0–80% in 20 minutes, but only on its RAPID Pro 320W Charging Station. On an ordinary USB-C wall charger, the bank charges at whatever that charger and cable can deliver. Estimated time to fill about 80Wh into the battery, from empty to roughly 80%:
| Charger | 0–80% (estimate) |
|---|---|
| EcoFlow RAPID Pro 320W station | ~20 min (EcoFlow figure) |
| 140W PD 3.1 USB-C charger | ~40 min |
| 100W USB-C charger | ~55 min |
| 65W USB-C charger | ~1.5 h |
| Car USB-C, 30W | ~3 h |
EcoFlow’s FAQ gives three tips for fast charging: use a fast-charge charger (65W or 100W PD and up), use a quality cable rated for 5A or 240W, and keep the cable short and the connectors clean.
Flying with it
At 99.54Wh, the RAPID Pro sits just under the 100Wh threshold that ICAO rules and most airlines use for carry-on power banks, and EcoFlow’s FAQ says it can go on board. Power banks belong in your carry-on, not checked luggage. Rules vary by airline and country, so check yours before you fly. The capacity is printed on the bank, which makes things easier at security.
Smart features
- LCD screen: shows charge level and live power, with a customizable standby display.
- EcoFlow app: includes a battery optimization mode that EcoFlow says extends the life of both the bank and the devices you charge.
- Pass-through charging: charge the bank and your devices at the same time, which is handy on a hotel nightstand with one outlet.
- Swappable magnetic cases: EcoFlow calls the design modular, with detachable magnetic covers.
Care and storage
EcoFlow rates the RAPID Pro for charging and discharging between 32°F and 104°F (0–40°C) and below 3,000 m. For storage, it recommends -4°F to 104°F (-20°C to 40°C) and a recharge at least once every three months. Don’t leave it on a car dashboard in summer. The cycle rating, more than 80% capacity after 300 cycles, is typical for a lithium-ion power bank. That works out to about a year of daily full cycles, or several years of travel use.
Two sample days (estimates)
Travel day: red-eye flight plus a layover
| What you charge | Energy used (estimate) |
|---|---|
| Phone, two top-ups | ~25Wh |
| Noise-canceling headphones | ~3Wh |
| Tablet for movies, one full charge | ~30Wh |
| Laptop, half a charge at the gate | ~25Wh |
| Total | ~83Wh |
That uses about everything the bank can deliver, so start the trip full and recharge at the hotel.
Conference or job-site day
| What you charge | Energy used (estimate) |
|---|---|
| Laptop, one full charge (13-inch) | ~50Wh |
| Phone, one full charge | ~17Wh |
| Smartwatch + earbuds | ~3Wh |
| Camera batteries (two) | ~10Wh |
| Total | ~80Wh |
A quick 20–40 minute top-up over lunch, if there’s a fast charger nearby, gives you a comfortable buffer for the afternoon.
What to pair it with
Because the retractable 60 cm USB-C cable is built in, you don’t need to pack a separate cable for the 140W port. To refill the bank quickly, pair it with a PD 3.1 wall charger rated 140W or more, or EcoFlow’s 320W charging station for the 20-minute claim. A short 240W-rated USB-C to USB-C cable for the second 140W port completes the kit.
Prefer a detachable magnetic module? The RAPID Pro X offers the same 99.54Wh and 300W total in a modular design, at a higher price.
Who it’s for
- Travelers who want the most capacity an airline normally allows in a carry-on.
- Laptop users who need 140W for fast charging, not just phone-level output.
- Remote workers running a Starlink Mini for a few hours between bigger power sources.
Looking for something larger for camping? A small power station like the Anker SOLIX C200 DC stores more than twice the energy, but it can’t fly.
FAQ
How many mAh is the EcoFlow RAPID Pro?
27,650mAh, which EcoFlow rates at 99.54Wh.
Can I take it on a plane?
Yes, in your carry-on. It’s under the 100Wh limit used by ICAO and most airlines. Check your airline’s rules before you fly.
Can it charge a MacBook Pro?
Yes. The built-in cable and one USB-C port each deliver up to 140W over PD 3.1, which is enough for fast charging on MacBook Pro models that support 140W.
How fast does it recharge?
EcoFlow says 0–80% in 20 minutes on its 320W charging station. On a 140W USB-C charger, expect roughly 40 minutes to 80% (estimate).
Will it power a Starlink Mini?
On paper, yes. The 140W PD 3.1 ports meet Starlink’s 100W (20V/5A) USB PD requirement. Expect roughly 2–3 hours of use (estimate).
Does it have a USB-A port?
No. All four outputs on EcoFlow’s spec list are USB-C, so older devices with USB-A plugs need a USB-C to USB-A cable or a small adapter.
Does it support pass-through charging?
Yes, according to EcoFlow’s FAQ.
Bottom line
The RAPID Pro 27K delivers close to the full carry-on limit with laptop-class 140W ports, a cable you can’t forget at home and app control, for $175.99 at EcoFlow’s current price. For travelers and remote workers who want one bank that can run a laptop, a phone and even a short Starlink session, it’s one of the most capable options under the 100Wh line.
