Fitbit Charge 6 Fitness Heart Rate Sleep Tracker GPS Smartwatch Black - Tested
Used
Why we picked it #1
This listing gets you the flagship Fitbit Charge 6 at a solid price, and what really stands out is that you're getting the authentic charger included—meaning you won't deal with aftermarket cables or extra purchases. The seller has a strong reputation, so you can feel confident about what you're receiving. Compared to some cheaper listings, you're paying a bit more, but you're getting the assurance of a tested unit and seller with lots of positive feedback. The few things to keep in mind: this is a used item, so expect some typical wear, and the listing mentions general warnings—nothing alarming, but it's not open-box or pristine. If getting a current Charge 6 with all original accessories from a vetted seller is your priority, this is one of the most trustworthy and complete options on the list. You might save a few bucks with other listings, but you'll often give up either charger certainty or seller track record.
Fitbit Charge 6 36MM Activity tracker
Used
Why we picked it #2
You're looking at the lowest price for a Charge 6 here—and that instantly makes this listing tempting if you're all about the best deal. It comes with the authentic charger, so you're not sinking extra cash into accessories. The tradeoff? You'll see minor scuffs on the face, bezel, and band—nothing major, just the kind of signs you'd expect on a well-loved device. If you care more about function than flawless looks, this is a sensible choice. You do give up a bit in terms of seller history compared to the top listing, and it doesn't highlight a thorough testing process. So, if you're after rock-bottom pricing and don't mind light cosmetic wear, this gives you unbeatable value. If you'd rather up your budget slightly for better cosmetic condition or a higher-confidence seller, options #1 and #6 are worth a peek.
Fitbit Versa 3 GPS Smart Watch w/ Heart Rate Monitor
Used
Why we picked it #3
This listing switches things up with a Fitbit Versa 3—a full-on smartwatch with GPS and heart rate monitoring. You’re not just getting the watch, but also extra face covers, which is a thoughtful add if you want more personalization. It’s being sold as-is by the original owner, which means you’re trusting their word on condition, but it’s a fair price for a watch that doubles as a fitness tracker and smart device. If you’re comparing with the Charge 6, you’re trading the latest sensors and slimmer band design for more smartwatch features and a slightly older model. Go with this if you want more than just fitness stats—for calls, apps, and a more watch-like look. For pure fitness tracking at the same price, though, the Charge 6 in the top spot is a better bet for up-to-date metrics and sensor improvements.
BLACK - FITBIT CHARGE 6 FITNESS / HEALTH TRACKER #156589#
Used
Why we picked it #4
Here, you're getting a used Charge 6 with the authentic charger included, but you’ll be paying the highest price among all the Charge 6 listings. While the device itself is still feature-rich and current, you’ll want to pay attention to a few things: the listing notes normal cosmetic wear (expect it to look 'used'), and accessories are only included if pictured, so double check what’s actually coming. More importantly, there's explicit uncertainty around battery life and you aren’t getting photos of the exact unit—so there’s a bit more risk than usual. If condition and full transparency matter to you, you might want to look at pick #1 or #2 where you’re either saving substantial money or getting a better balance of trust and disclosure. This one only makes sense if the included charger and device color are exactly what you want and you’re comfortable with the listed risks.
Fitbit Versa 2 - Health & Fitness Smart Watch Copper Rose / Pink Band FB507
Used
Why we picked it #5
This listing is for a Versa 2, so you’re getting an older, more affordable Fitbit smartwatch. You’re saving some cash, and the seller’s near-perfect feedback gives you good peace of mind. It’s a smart value pick if you care more about smartwatch features than having the absolutely latest health sensors. The caveat: this is an older model compared to the Charge 6, so you miss out on new features like improved heart tracking, ECG, and Google integrations. The listing isn’t clear on whether a charger is included, so that’s an extra step for you to confirm. Overall, this is a smart budget option if you want smartwatch functionality from a seller you can trust, but if you want the best health features, it’s worth stretching your budget to a Charge 6 listing.

Fitbit Charge 6
Fitbit Charge 6: Why Buy Used?
The Fitbit Charge 6 (October 2023) is Fitbit's most refined fitness band ever — flagship-grade health sensors, built-in GPS, Google Wallet NFC, ECG, EDA stress sensor, and crucially the return of the tactile haptic side button that was sorely missed on the Charge 5. Compared to its predecessor, Fitbit cites roughly 60% improved heart-rate accuracy, plus Google integration (YouTube Music controls and Google Maps turn-by-turn directions on your wrist). It's the slim-band counterpart to a full smartwatch — discreet, lightweight, and packed with health features.
At roughly two years old, the Charge 6 sits at a sweet spot on the used market: $159 new in 2023 has dropped substantially while the watch retains its full software support and feature set.
What Makes the Charge 6 Stand Out
- Restored tactile side button — A real haptic button returns after the Charge 5 attempted (and failed) capacitive-only controls. This is a meaningful UX recovery and the single biggest day-to-day improvement.
- Built-in GPS — No phone needed for outdoor workout tracking. Run, cycle, and hike routes record directly on the band.
- Google Wallet NFC payments — Tap-to-pay anywhere Google Pay is accepted.
- YouTube Music + Google Maps integration — Skip music tracks and get turn-by-turn navigation on a band-class wearable. Genuinely unusual at this size.
- ECG (electrocardiogram) — FDA-cleared atrial fibrillation detection via the Fitbit app.
- EDA stress sensor — On-demand stress assessments using electrodermal activity.
- Daily Readiness Score — Fitbit's signature 0-100 daily recovery score, synthesizing HRV, sleep, and activity. (Some Daily Readiness features may require Fitbit Premium.)
- 7-day battery life — Class-leading in the slim-band category, even with frequent feature use.
- 5ATM water resistance — Swim-proof, pool and shallow-water safe.
- AMOLED display with always-on option — Vivid colors. Always-on shortens battery substantially.
- iOS 15+ and Android 9.0+ compatible — Works with both iPhone and Android via the Fitbit app.
What the Charge 6 Does NOT Do
- No phone calls — No speaker; the Charge 6 shows call notifications but you cannot speak through it.
- No Wi-Fi — Updates and syncs go through your phone's Bluetooth connection.
- No third-party app store — Unlike Versa-series smartwatches, the Charge 6 is band-class with limited app extensibility.
- AMOLED burn-in risk — Heavy always-on use over years can leave ghost UI imprints.
Who Is the Fitbit Charge 6 For?
- Buyers who want a slim, discreet tracker — not a chunky smartwatch — but with full health sensor depth (ECG, EDA, SpO2, Daily Readiness).
- Google ecosystem users — Google Wallet, YouTube Music control, and Google Maps turn-by-turn integration matter.
- Runners and cyclists who want built-in GPS without paying smartwatch prices.
- Existing Fitbit users — your historical data, Premium subscription, and routines carry over seamlessly.
- Sleep and stress trackers — the EDA sensor and Daily Readiness Score are differentiated against many smartwatches in this price band.
Smart Tips for Buying Used
- Check that the proprietary USB charging clip is included — Fitbit does not use USB-C. Replacement clips exist on aftermarket sites but add cost and risk.
- Verify the haptic side button clicks — its restoration is the headline Charge 6 fix; failure here is a regression worth catching.
- AMOLED burn-in check — ask the seller for a photo on a uniform white or gray screen, especially if always-on display was used heavily.
- Confirm the Fitbit account has been removed — a factory reset clears the previous owner's account, but ideally the seller has already done it.
- Battery at 2 years — typically still strong; 7-day battery may degrade modestly. Daily Readiness Score requires 3 nights of sleep data to calibrate after setup.
- Bands are interchangeable and cheap — third-party Charge 6 bands are abundant. Don't reject a deal over a worn band.
Frequently Asked Questions
Is the Fitbit Charge 6 worth buying used?
Yes. The Charge 6 is genuinely the most refined Charge generation — the restored haptic button alone fixes the Charge 5's biggest UX flaw, and Google integration plus ~60% improved heart rate accuracy make it a meaningful upgrade. At used prices well below the $159 launch, it's a strong value for buyers who want a slim band rather than a full smartwatch but still want ECG, EDA, GPS, and Daily Readiness Score.
Does the Fitbit Charge 6 work with iPhone?
Yes. The Charge 6 is fully compatible with iPhone (iOS 15+) via the Fitbit app. ECG, GPS, Google Wallet, sleep tracking, Daily Readiness Score, and notifications all work on iPhone. Apple-exclusive features like Siri are not available, but core Fitbit functionality is fully supported.
What's the difference between the Charge 6 and the Charge 5?
The Charge 6 is the more refined model. Three big differences: (1) Restored tactile haptic side button (the Charge 5's capacitive-only controls were widely criticized), (2) Improved heart rate accuracy (Fitbit cites ~60% improvement), and (3) Google integration — YouTube Music controls and Google Maps turn-by-turn directions. The form factor and core sensor lineup are very similar. If choosing between the two used, the Charge 6 is clearly preferable.
Can the Fitbit Charge 6 detect atrial fibrillation (AFib)?
Yes. The Charge 6 includes an ECG sensor that can detect irregular heart rhythm consistent with AFib via the Fitbit app. This is FDA-cleared in the United States. Setup requires completing the ECG assessment in the Fitbit app, which takes about 30 seconds. The feature is on-demand assessment, not continuous automatic detection.
What is Daily Readiness Score and is it worth it?
Daily Readiness Score is Fitbit's signature health feature — a 0-100 morning score based on overnight HRV, recent activity load, and sleep quality. A high score (70+) means you're recovered for hard training; low (under 30) suggests rest. It's particularly valuable for athletes who train consistently and want data-backed recovery guidance. Note that some Daily Readiness Score features may require Fitbit Premium subscription.
What should I check before buying a used Charge 6?
(1) Charging clip included — Fitbit's proprietary USB clip is essential and not USB-C compatible; (2) Haptic side button works — the restored tactile button is the Charge 6's headline UX fix; (3) AMOLED burn-in — ask for a photo on a white screen if always-on display was used heavily; (4) Account removed — confirm the previous owner's Fitbit account has been cleared (or be prepared to factory reset); (5) GPS lock test — for outdoor workout users, ideally confirmed within 60 seconds outdoors before purchase.
