Is the Anker 737 Power Bank (PowerCore 24K) overhyped?

Marketing claims partially hold up for core performance features but are contradicted by serious battery longevity and hardware reliability issues. The 140W output and OLED display are validated by 6 and 5 user mentions respectively, with owners confirming real-world performance matches claims. However, battery health collapsing to 5% after just 136 cycles and a USB-C port dying after 3 months directly undermine claims of 'Smart charging technology' and '10 safety features for ultimate protection' — suggesting the premium price ($) does not guarantee long-term reliability.

Issues Reported by Users
Battery health degrades catastrophically fast, with one owner reporting a drop to 5% capacity after only 136 charging cycles, and another unit shutting off at 50% charge when unplugged.
“After 136 Charging Cycle, battery health drop to 5%”
vs Marketing: Marketing claims 'Smart charging technology' and the ability to 'keep multiple devices running for days', but real-world battery health collapses well before a reasonable product lifespan, making sustained multi-device use impossible over time.
At least one owner experienced a USB-C port failure after approximately 3 months of normal use, raising serious build quality concerns for a premium-priced device.
“Mine was great at first but one of the USB-C ports died after about 3 months of normal use. For the price I expect the ports to last longer than a single season.”
vs Marketing: Marketing touts 'A combination of 10 safety features that work together to provide the ultimate protection for your devices', but physical port failure within a single season contradicts claims of robust protective design.
Multiple users flag the unit as too large and heavy for casual carry, limiting its practical use to backpack or desk scenarios rather than everyday pocket portability.
“The power is awesome but this thing is a brick – it's heavy enough that I don't want it in my pocket. Great for a backpack or desk, not something you casually carry all day.”
vs Marketing: Marketing emphasizes 'Ultra-Powerful Two-Way Charging' and broad device compatibility without adequately disclosing the physical trade-off in size and weight that limits real-world portability.
Only 2 USB-C ports are available even on the higher-capacity variant, forcing users with two phones and a laptop to charge devices sequentially rather than simultaneously.
“The only thing i don't understand is they still only have 2 USB C even on the 26 mah version. Makes no sense. I have 2 phones and want to get a usb C charging laptop. I will have to take turns in use.”
vs Marketing: Marketing claims the bank can 'charge multiple devices at once', but the 2-port limitation means users with three USB-C devices cannot achieve true simultaneous charging as implied.
At least one prospective buyer declined to purchase specifically because the battery cells are not user-replaceable, making any repair equivalent to buying a new unit and raising sustainability concerns.
“I was about to grab the 737 but backed off after realizing the cells aren't user replaceable and repairs are basically a new unit. That's too much e-waste for a premium price.”
What Users Like
Owners consistently confirm the 140W output delivers on its promise, with the unit recognized by MacBook Pro and gaming handhelds as a full-power charger across 6 feature mentions.
“I've had the 737 for about a year and it's been a beast – it'll top up my work laptop and phone crazy fast, and the 140W output really does what Anker claims. It's basically my travel wall outlet now.”
140W Charging Output PerformanceThe real-time wattage and time-to-empty OLED display is praised as genuinely useful for managing multiple devices, validating the marketing claim across 6 feature-related mentions.
“Didn't think I'd care about the little screen but it's actually super handy. Seeing real-time wattage and estimated time to empty makes it way easier to manage multiple devices.”
OLED Display UtilityOwners confirm the unit runs Steam Deck and Nintendo Switch at full power without throttling, making it a reliable travel solution for handheld gaming across long flights.
“This is my go-to battery for the Steam Deck and Switch – both run full power and the bank barely breaks a sweat. I can game cross-country flights without hunting for outlets.”

Anker Prime 27650mAh Power Bank (A1340)
