Why We're Not Stocking PeakDo Batteries Anymore

Over the past year, PeakDo's Starlink Mini batteries kept getting "better." First they advertised about 4 hours. Then 5. Then 5.5. But the label never changed: every one still says 99 Wh.
Batteries don't get more runtime out of thin air. So we bought a LinkPower 3 straight from PeakDo's website and opened it.
Inside, the cells add up to about 117 Wh, not 99. Someone even wrote "6500" on the pack, the size of the cells really inside. Our tests back it up: the cells released at least 111 Wh.
Why label a 117 Wh battery as 99? Because 100 Wh is the airline limit. "99 Wh" means it can go in your carry-on. Starting January 1, 2027, a battery that's really 117 Wh would be forbidden on most airlines, no matter what the label says.
That's why we're not going to stock PeakDo anymore.
If you have a LinkPower 1 from us, you're fine. It has the correct cells for 99 Wh, and we've sold a lot of them.
What we found inside a LinkPower 3
We put one of the LinkPower 3 units we bought from PeakDo's website on our test bench and opened it.

The marking. The wrap around the five cells is hand-marked "6500". The cells under it are printed "5500", the same cells PeakDo's FCC photos show. [S8]
The math.
- Five 5,500 mAh cells: 99 Wh, which is the label.
- Five 6,500 mAh cells: 117 Wh, about 18% more than the label.
Our tests. We ran the pack all the way down twice. After accounting for our test board's own losses, the cells released at least 111 Wh both times, and each cell held about 6.4 Ah. A real 5,500 mAh cell holds about 5.6 Ah. That matches PeakDo's 5.5-hour claim almost exactly, and it's more than a 99 Wh battery can do. [S6][S9]

What we conclude. Put side by side:
- the cells are printed "5500";
- the pack wrap is hand-marked "6500";
- each cell held about 6.4 Ah;
- the cells released at least 111 Wh.
The evidence strongly suggests these are 6.5 Ah cells from Far East Battery (more on them below) relabeled as 5.5 Ah cells, so the pack can be labeled 99 Wh and stay under 100 Wh. The "6500" written on the pack shows that whoever built it knew they were 6,500 mAh cells.
We're not the only ones who've measured more than 99 Wh. An independent YouTube reviewer measured 104 Wh at the output of a LinkPower 2 labeled 99 Wh: "This battery is higher than the claimed 99wh capacity!" [S11]
The cell maker: Far East Battery (FEB)
Photos PeakDo filed with the FCC show the cells inside: light-blue cells from a Chinese maker called Far East Battery (FEB), printed 5500 mAh. [S8][S17]
FEB sells the same size of cell in three capacities. A LinkPower pack holds five of them:
| FEB cell | Energy for five cells | Which LinkPower | How sure we are |
|---|---|---|---|
| 5.5 Ah (5500 mAh) | ≈ 99 Wh, under 100 Wh | LinkPower 1, the one we've carried | Correct cells. LinkPower 1 owners have nothing to worry about. |
| 6.0 Ah (6000 mAh) | ≈ 108 Wh, over 100 Wh | LinkPower 2 | Our belief, not a teardown. PeakDo's runtime claim jumped from "~4 hours" to "over 5 hours" at the same 99 Wh label [S2][S3], and an independent reviewer measured 104 Wh [S11]. |
| 6.5 Ah (6500 mAh) | ≈ 117 Wh, over 100 Wh | LinkPower 3 | Certain. "6500" on the pack wrap, plus our test: at least 111 Wh from the cells. |
Sources: FEB's 5500 mAh cell in PeakDo's FCC photos [S8] and independent tests [S9]; FEB's 6000 mAh datasheet [S14] and announcement [S15]; FEB's 6500 mAh datasheet [S16].

A real 5500 cell runs dry at about 5.6 Ah. The LinkPower 3's cells kept going to 6.4 Ah, which is what FEB's 6500 cell does.

What PeakDo has claimed, and when
| When | Product | What PeakDo said | Label |
|---|---|---|---|
| Dec 2025 | LinkPower 2, FCC user manual | "~4Hours for Starlink Mini" [S2] | 99 Wh |
| Dec 31, 2025 | LinkPower 2, PeakDo YouTube | "99Wh capacity now provides over 5 hours of runtime (up from 4+ hours)" [S3] | 99 Wh |
| Aug 2026 | LinkPower 3, PeakDo blog | "the 5.5-hour figure is based on testing under a standard 20W load" [S4] | "strictly capped at 99Wh" |
| Nov 2026 | LinkPower 3 product page | "Up to 5.5 hours on a full charge. (Runtime measured at 20W Starlink Mini power consumption)" [S5] | 99 Wh |
The advertised hours kept going up while the label stayed at 99 Wh.
The Wh number on a battery is how much energy is inside it. A little gets lost on the way to your Mini, so you never get quite all of it. The Starlink Mini usually pulls about 18–20 W, so a real 99 Wh pack runs it for about 4.5 to 5 hours. You can't get 5.5 hours at a steady 20 W out of 99 Wh.
We've been offered the same shortcut, and said no
We're an American company, and overseas suppliers have offered to relabel higher-capacity cells as 99 Wh for us. We've always said no, because a pack whose cells add up to more than 100 Wh can't legally be sold or flown as a sub-100 Wh battery, no matter what the label says.
Why the label matters
Airlines decide what you can carry on by the Wh rating. From January 1, 2027, the IATA airline rules most airlines follow won't allow power banks whose cells add up to more than 100 Wh. The current option to fly a 100 to 160 Wh power bank with airline approval goes away. [S10]
PeakDo calls its packs "airline-approved" and the Ultra "IATA Flight-Approved". [S5][S12] A pack built from five 6.5 Ah cells, about 117 Wh, would be forbidden under IATA airline rules from 2027, even with 99 Wh printed on it. Airport security reads the label; they don't open the battery. You'd be the one carrying it.
What this means if you own one
- LinkPower 1 from us: nothing to worry about. It uses the correct 5.5 Ah cells, about 99 Wh.
- LinkPower 2 or 3: it will still power your Mini, and nothing here says it's unsafe to use at home or on the road. Before flying in 2027, check your airline's rules for power banks, and know that the label may not reflect what's inside.
