Anker’s Prime Power Bank (26K, 300W), model A110A, can push 300W across three ports at once and recharge at up to 250W using both USB-C inputs, according to Anker’s US product page. Anker says that refills it to 50% in about 13 minutes and to 80% in about 40. The 26,250mAh pack works out to 99.75Wh, just under the 100Wh line that U.S. airline rules use for carry-on batteries. It weighs 1.32 pounds and adds a smart display, Bluetooth app control and two 140W USB-C ports. On October 17, 2026, Anker’s US store listed it at $229.99. This review covers the specs, worked laptop and device charge estimates, recharge options and how it compares with the DC power bank I use for Starlink Mini.

300W across three ports: what that means
Most laptop power banks top out at 100W or 140W total. The Prime’s 300W total means each USB-C port can run at its full 140W while the USB-A port adds up to 22.5W, as long as the combined draw stays at or under 300W. Anker’s PowerIQ 4.0 shifts power toward the devices that need it most.
| Combination | Approximate draw | Fits within 300W? |
|---|---|---|
| 16-inch MacBook Pro (140W) + second 140W laptop | 280W | Yes |
| Two 140W laptops + phone on USB-A (20W) | 300W | Yes, at the limit |
| MacBook Air (about 70W) + iPad (about 30W) + phone | About 120W | Yes, easily |
| Steam Deck + Nintendo Switch + phone | Under 100W | Yes |
A MacBook Pro only pulls 140W over USB-C with a cable rated for USB PD 3.1 EPR (28V⎓5A). Anker also notes that 140W input needs a 140W charger and a 5A cable.
How many charges? Worked estimates
Anker says 30–45% conversion loss is normal, and that a full 26,250mAh pack provides about 15,200mAh to your devices. I use that range, so about 55–70Wh actually reaches the device out of 99.75Wh: charges ≈ usable Wh ÷ device battery Wh.
| Device (battery) | Estimated full charges |
|---|---|
| Typical flagship phone (about 15Wh) | About 3.7–4.7 |
| 13-inch MacBook Air (52.6Wh, Apple spec) | About 1.0–1.3 |
| Steam Deck OLED (50Wh, Valve spec) | About 1.1–1.4 |
| 16-inch MacBook Pro (100Wh, Apple spec) | About 0.55–0.7 (a solid top-up) |
Running a Starlink Mini from it
Starlink’s spec sheet lists the Mini at 25–40W average, with USB-C PD power requiring at least 100W (20V/5A) through Starlink’s USB-C to barrel jack cable. The Prime’s 140W USB-C ports clear that bar. At my own measured 22W draw, or Starlink’s 25–40W range, 55–70Wh works out to roughly 1.4 to 3.2 hours by my estimate. For longer Starlink sessions, my XTAR MP158 review covers a 158Wh bank with a dedicated DC output that ran my Mini without issues.
Recharging the Prime
| Charging source | Max input | Anker’s time / my estimate |
|---|---|---|
| Two 140W USB-C chargers with 5A cables | 250W | 50% in 13 min; 80% in 40 min (Anker) |
| Anker Prime Charging Base | 150W | Not published; roughly an hour or more by my estimate |
| One 140W USB-C charger | 140W | Not published; about an hour or more by my estimate |
| 100W laptop charger | 100W | Roughly 1–1.5 hours by my estimate |
| Portable power station’s USB-C port (100–140W) | 100–140W | Similar to a wall charger of the same wattage |
My one-hour-plus estimates come from 99.75Wh ÷ charger watts, plus time for the slower final stretch and some charging loss. Anker notes that input power tapers to protect the battery, and recommends a charger of at least 100W if you want to charge devices while the bank itself is charging.
Flying with it
At 99.75Wh, the Prime sits just under the 100Wh threshold that FAA guidance uses for spare lithium batteries in carry-on bags. Anker markets it as flight-approved. Larger banks between 101Wh and 160Wh need airline approval, and spare lithium batteries belong in carry-on luggage, not checked bags. Always check your airline’s current rules before you fly.
Prime 26K vs a DC power bank for Starlink
| Anker Prime 26K 300W | XTAR MP158 (my Starlink bank) | |
|---|---|---|
| Capacity | 99.75Wh | 158Wh |
| Best output | 2 × 140W USB-C, 300W total | Dedicated DC output for Starlink Mini, 100W USB-C |
| Carry-on | Under 100Wh | Over 100Wh; needs airline approval |
| Best for | Laptops, travel, fast recharging | Long Starlink Mini sessions |
Power bank or small power station?
I use an Anker SOLIX C200 DC for all-day laptop work, so I often get asked whether a big power bank like the Prime can replace it. They overlap, but they’re built for different days:
| Anker Prime 26K 300W | Anker SOLIX C200 DC (I own one) | |
|---|---|---|
| Capacity | 99.75Wh | 192Wh LiFePO4 |
| Max output | 300W total, 2 × 140W USB-C | 200W, one 140W two-way USB-C plus 100W and 15W USB-C |
| Fastest recharge | 80% in about 40 min (250W dual input) | 80% in about 1.3 h with a 140W USB-C charger |
| Solar charging | Not a listed input | Up to 100W; about 3 h in LA sun with my 100W panel |
| Carry-on friendly | Yes, under 100Wh | Over 100Wh; check airline rules |
| Best day | Flights, conferences, two laptops at full speed | Full workdays, camping, outages, solar top-ups |
In practice, the Prime wins when weight, flights and charging speed matter. The C200 DC wins when you need roughly twice the energy and want to refill from solar. My Anker SOLIX C200 DC review covers how it handled a full day of MacBook and phone charging.
Who the Prime 26K is for
- Travelers with 14- or 16-inch laptops who want a carry-on-friendly bank that can deliver a full 140W.
- Creators and photographers charging a laptop, a camera and a phone at once. Anker lists the Canon R5 Mark II and DJI Mavic 3 among compatible devices.
- Handheld gamers: a Steam Deck OLED gets more than one full charge by my estimate.
- Not ideal for multi-day off-grid use, 12V devices or long Starlink sessions, where a larger LiFePO4 station or a DC bank fits better.
Setup tips
- Use 5A, 240W-rated (EPR) USB-C cables for 140W charging and recharging; ordinary 60W cables limit speed.
- Pair the app over Bluetooth to see port-by-port output and adjust power distribution preferences.
- Use both USB-C inputs with two 140W chargers when you need the fastest top-up before a flight.
- Keep it cool: Anker suggests using it at 32–77°F in a ventilated spot for the best charging speed.
- Charge laptops first when you need full speed; the USB-A port is best for earbuds and phones.
Strengths and trade-offs
| Strengths | Trade-offs |
|---|---|
| 300W total with two 140W USB-C ports | 99.75Wh capacity caps big-laptop charges |
| 250W dual-port recharging | Fastest recharge needs two 140W chargers |
| Under 100Wh for carry-on travel | 1.32 lb is heavy for a pocket |
| Display and app with per-port stats | No DC barrel output for Starlink or 12V gear |
FAQ
How many watt-hours is the Anker Prime 26K?
26,250mAh at about 3.8V nominal works out to 99.75Wh, just under 100Wh.
Can it charge two laptops at once?
Yes. Each USB-C port supports up to 140W, and total output is 300W, so two 140W laptops plus a phone fit.
How fast does it recharge?
Anker says 50% in about 13 minutes and 80% in about 40 minutes using both USB-C ports, with two 140W chargers and 5A cables.
Is it allowed on planes?
At 99.75Wh it’s under the 100Wh carry-on threshold in FAA guidance, and Anker calls it flight-approved. Pack it in carry-on luggage and check your airline’s rules.
How many times can it charge a MacBook Air?
About 1 to 1.3 full charges of a 13-inch MacBook Air’s 52.6Wh battery, by my estimate using Anker’s conversion-loss range.
Will it run a Starlink Mini?
Yes, through Starlink’s USB-C cable, since the Prime’s ports exceed the 100W PD requirement. Expect roughly 1.4–3.2 hours by my estimate.
Does the charging base come with it?
Not with the standard version. Amazon lists the base-included bundle separately.
Verdict
The Anker Prime 26K 300W is built for people who carry big laptops and want a flight-friendly bank that can run two of them at full speed and refill quickly between legs. If your priority is long Starlink Mini sessions or 12V gear, a larger DC power bank or a small power station makes more sense. I’ll add measured output and recharge results once I test one.
