No explicit watt-hour rating in our sources
INIU states the 25,000mAh capacity without an explicit Wh rating, so this dossier leaves watt-hours unknown. The mAh label alone does not establish usable USB energy or a device recharge count.

INIU P63-E1 25,000mAh 100W Power Bank review
Exact model: P63-E1
Product identity · checked 2026-10-12
Our take
Choose this for a USB-C laptop you charge on its own at up to 100W. Plug in a phone too and the laptop port drops to 65W. That matters if your laptop needs more power while you work.

The buying decision
Should you buy it?
For a laptop charged on its own
INIU rates USB-C1 at up to 100W with PD3.0 and PPS support, alongside a 45W USB-C2 and 18W USB-A. Use USB-C1 alone for the full laptop rating. With USB-C2 connected, the allocation becomes 65W for the laptop and 45W for the second device.
Know this before you buy
INIU lists 100W for USB-C1 alone, 80W with all three ports active, and 110W for the best dual pair. The comparison chart adds a 163W figure that equals the arithmetic port sum. The actual dual allocation is 65W plus 45W, not 100W plus 10W. All three ports allocate 65W to USB-C1 and share 15W between the others.
Match your laptop’s USB-C Power Delivery requirement to the bank’s port profile and cable. Check laptop compatibility.

What this score tells you
Each reading gets a percentile within its group. Higher output, capacity and input score better. Lower weight scores better. Ties share a midpoint. We combine those percentiles using the weights above and round the final result.
A score of 100 means the strongest combination in this peer set, not a perfect power bank. Scores can change when we update a rating or publish another model. Compare scores within the same group.
The score does not include wireless charging, weather protection, price or safety. Capacity is the manufacturer’s mAh rating, not usable USB energy or a phone recharge count. Check the verdict and charging limits before you buy.
Formula version 1.0. Source dates are attached to each reading. See the full method.
What changes the choice
Other drawbacks to consider
Before connecting devices
Ports and charging behavior
A port’s published maximum and the combined multi-port limit are separate ratings. A device can draw less than the bank’s maximum based on its own requirements and the negotiated charging profile.
Recharge over USB-C1 at up to 65W
INIU lists input from 5V 3A up to 20V 3.25A through USB-C1 and ties its 1.4-hour full-recharge claim to a 65W or stronger charger and cable. A weaker charger refills the bank at its own lower rate.
The two lower-power ports share 15W
USB-C2 plus USB-A together are capped at 15W. Keep the laptop on USB-C1 when both lower ports are in use, since that pair cannot draw from the higher dual-port budgets.

Exact-model questions
Frequently asked questions
Can one laptop draw 100W while another device charges?
No. INIU specifies 65W on USB-C1 plus 45W on USB-C2 when both are active. USB-C1 also drops to 65W when USB-A is used. To get the full 100W laptop output, leave the other ports empty.
Is the P63-E1 the same bank as the P62-E1?
No. The P63-E1 lists 25,000mAh, 100W single-port output and 392.3g against the P62-E1 with 20,000mAh, 65W and 323g. They are separate Cougar-series models with separate listings.
