A colleague lent me his RAVPower RP-PB054 during a week-long conference where the venue’s outlets were always occupied by the time I found my seat. What sold me on it was not the phone charging, every power bank does that, it was plugging my laptop’s own wall charger straight into the built-in AC outlet on the side and getting a real laptop charge out of a battery pack for the first time.
Here is a walkthrough of a full day with the RP-PB054, from the morning it left the charger to the point it finally tapped out that evening, along with the setup details and quirks worth knowing before you buy one.
Morning: What You Get in the Box
The PD Pioneer RP-PB054 is built around a 20,000mAh (74Wh) battery, which keeps it just under the 100Wh limit most airlines allow in carry-on luggage. Unlike the simpler brick-style power banks, this one has an actual AC outlet built into the side alongside standard USB ports.
- USB-C output with 30W Power Delivery 3.0
- USB-A output with 18W Quick Charge 3.0
- Built-in AC outlet rated up to 80W (100W peak)
- USB-C input for recharging, also supports 30W Power Delivery
- Blue LED indicators showing remaining charge level
The physical size surprised me at first, it is roughly 6 inches long with a boxy 2.7-inch square profile and weighs about 1.46 pounds. It does not slip into a jacket pocket the way a slim phone-only power bank would, this is something you pack in a bag.
Midday: Charging a Laptop From the AC Outlet
This is the feature that actually matters for this device. At the conference, I plugged my laptop’s own charging brick directly into the AC outlet on the RP-PB054 exactly like plugging into a wall socket. It worked, and my laptop charged at a reasonable rate through a full afternoon session.
- Press the power button once to wake the display before plugging anything in.
- Plug your laptop’s standard wall charger into the AC outlet, no special cable needed.
- Watch the blue LED indicators, a laptop charging through the AC outlet draws down the bank noticeably faster than a phone would.
- For lower-wattage laptops (under 65W), expect one nearly full charge cycle before the bank needs a recharge itself.
The rated 80W (100W peak) AC output covers most ultrabooks and many mid-range laptops, but higher-draw gaming laptops that need 130W or more chargers will not get a usable charge from this outlet. Check your laptop’s charger label for its wattage before assuming it will work.
Afternoon: Phone and Tablet Charging Alongside the Laptop
What impressed me most was using the AC outlet and a USB port at the same time without either output slowing to a crawl. I charged my laptop through the outlet while topping up a phone on the USB-C port simultaneously, and both devices still charged at a reasonable pace. The 30W USB-C output alone is enough for most phones to hit a fast charge speed comparable to their included adapter.
- Use the USB-C port for phones and tablets that support Power Delivery fast charging.
- Use the USB-A Quick Charge port for older devices or accessories without USB-C.
- Reserve the AC outlet specifically for laptops or devices with a standard wall plug.
Evening: Recharging the Bank Itself
Recharging is straightforward since the RP-PB054 accepts USB-C Power Delivery input, meaning a compatible fast charger can refill it considerably quicker than the Micro-USB-only banks I have used in the past. A full recharge from near-empty using a 30W or higher PD charger took a few hours rather than the better part of a day.
Air vents built into the bottom of the unit help manage heat during heavier use, which I noticed as a faint warmth rather than anything concerning while the laptop was charging through the AC outlet for an extended stretch.
Troubleshooting Notes
- AC outlet not turning on: some units require a firm press-and-hold on the power button specifically before the AC inverter activates, a quick tap only wakes the USB ports.
- Laptop not charging through the outlet: confirm the laptop charger’s wattage does not exceed 80W continuous draw.
- Bank shuts off during use: built-in protection circuits can trip under a sudden power spike, unplug everything and restart the unit.
- Slow recharge speed: confirm the charger plugged into the bank supports USB-C Power Delivery, a standard 5W phone charger will take far longer than expected.

Frequently Asked Questions
Can I bring the RP-PB054 on a plane?
Yes, at 74Wh it is under the common 100Wh airline carry-on limit, but it must travel in carry-on luggage rather than checked bags. Confirm your specific airline’s battery policy before flying.
Does the AC outlet work with any laptop charger?
It works with most laptop chargers rated at or under 80W continuous draw (100W peak). Check the wattage printed on your laptop’s charging brick before relying on it for a full workday.
Can I charge the power bank while it is charging other devices?
Pass-through charging is possible but is not the ideal way to use it long-term, since it generates extra heat and can add wear to the battery cells over time.
How does it compare to a smaller USB-only power bank?
It is heavier and bulkier, but the built-in AC outlet is the real differentiator, a standard USB-only bank simply cannot charge a laptop through its original wall charger the way this one does.
Conclusion
By the end of that conference day, the RP-PB054 had charged my laptop through a full afternoon, kept my phone topped up, and still had enough left for a coworker’s tablet before I finally plugged it back in that night. The AC outlet is the feature that justifies the size and weight, if you regularly need to charge a laptop away from an outlet, this is one of the few power banks that genuinely handles it.
