For portable sound, choose Charge 4 for louder output and USB‑C; pick Charge 3 for lower price, stereo sound, and calls.
JBL Charge 4
JBL Charge 3
Budget Route
- Want the lowest out‑of‑pocket.
- Need a built‑in mic for calls.
- OK with micro‑USB charging.
JBL Charge 3
Balanced Route
- Prefer louder output and fuller bass.
- Like USB‑C and faster top‑ups.
- Plan to link speakers with Connect+.
JBL Charge 4
Portable Bluetooth speakers live on patios, desks, and backpacks. These two hit the same jobs with different angles: one leans on louder power and USB‑C, the other keeps the price down and keeps a mic. You’ll get a fast verdict and the trade‑offs that push most buyers one way or the other.
In A Nutshell
Pick the newer model if you want stronger output for outdoor space and a modern USB‑C charge port. Stick with the older model if budget matters, you like true stereo drivers in this size, and you want speakerphone calls. Both claim 20 hours on a charge and both are IPX7, so water isn’t the decider here.
Side‑By‑Side Specs
JBL Charge 4 — What We Like / What We Don’t Like
✅ What We Like
- 30W RMS output that carries better in open space.
- USB‑C charging with a quicker top‑up time than the older plug.
- Lower bass floor (rated to 60 Hz) for punchier low end at this size.
- JBL Connect+ linking for bigger sound with compatible models.
- Same 20‑hour battery claim while adding a larger 7500 mAh pack.
⚠️ What We Don’t Like
- Heavier body than its sibling, which you feel in a day‑pack.
- No built‑in microphone for calls or voice prompts.
- Mono driver layout; stereo separation needs a second unit.
JBL Charge 3 — What We Like / What We Don’t Like
✅ What We Like
- Lower street price, especially in JBL’s refurb store.
- Dual drivers yield native stereo without pairing a second speaker.
- Built‑in mic handles quick calls and voice prompts.
- Solid 20‑hour claim with a still‑useful 6000 mAh pack.
- Aux‑in keeps older sources in the mix.
⚠️ What We Don’t Like
- Micro‑USB charging feels dated and takes a bit longer.
- Lower rated output and bass floor than the newer model.
- Ships with JBL Connect; you may need a firmware update for Connect+.
Charge 4 Or Charge 3: Which Fits You Better
Performance & Speed
The newer unit is rated at 30 watts RMS and uses a single 50×90 mm transducer. That extra headroom brings more punch for patios, park tables, and backyard noise. The older model runs a two‑driver layout rated at 2×10 watts. In tight rooms it sounds lively and gives you genuine left/right separation from one can—handy for podcasts, pianos, and acoustic sets.
On paper the lower cutoff also tilts toward the newer unit (60 Hz vs 65 Hz). That five‑hertz edge isn’t night‑and‑day, but it lines up with how these two feel: the newer one pushes more sub‑bass tone at moderate volume. If you’re often outside with wind, chatter, and street noise, louder output usually wins.
Battery & Charging
Both advertise up to 20 hours per charge. The newer unit gets there with a 27 Wh pack (about 7500 mAh at 3.6 V) and a faster 4‑hour charge time. The older one uses a 22.2 Wh pack (about 6000 mAh) and needs about 4.5 hours. In day‑to‑day use that means you can leave either on the porch all weekend without hunting a wall. If you do need a top‑up before a bike ride, USB‑C on the newer model is simply easier to live with.
Ports & Connectivity
Both keep the 3.5 mm aux input for set‑ups where Bluetooth isn’t ideal. Both act as power banks with 5V/2A output. For multi‑speaker sessions, the newer unit uses JBL Connect+, which links over 100 compatible speakers. The older unit shipped with JBL Connect but can be upgraded via the app to Connect+ on most units. Connect+ does not mix with PartyBoost models, so don’t plan to link with a Flip 5, Flip 6, or Charge 5—those speak a different language.
Software & Updates
JBL’s Portable app (formerly Connect) handles firmware updates and pairing modes (party or stereo). If you pick up the older model, run the app the first night and check for updates to enable Connect+ and features that shipped later in its life. The newer model pairs two phones at once; the older one pairs up to three, which some families enjoy when trading the DJ seat.
Pricing & Packages
New stock rotates toward the latest generation, so your best deals on these two live in JBL’s refurb shelves. The newer model has carried a higher list price from launch. The older one undercuts it and often shows bigger discounts when available. Both still include the audio cable input and the familiar rubberized shell, so value comes down to your priorities: louder output and USB‑C, or stereo drivers and a mic at a lower number.
ℹ️ Good To Know: JBL’s Connect+ speakers link with each other, but PartyBoost models don’t cross‑link with Connect/Connect+. Plan your mix before you buy.
Price, Value & Ownership
Here’s the quick math on total cost and living with each model. Numbers below lean on JBL’s U.S. listings; refurbs come and go, so treat them as snapshots.

Decision Guide
✅ Choose JBL Charge 4 If…
- You want the louder option for porches, parks, and backyard dinners.
- You prefer USB‑C charging and a faster top‑up before heading out.
- You plan to link multiple speakers using Connect+ for bigger events.
✅ Choose JBL Charge 3 If…
- You want the lowest price while staying in the same rugged family.
- You like native stereo from one unit and the ability to take calls.
- You don’t mind micro‑USB charging or running the app once to update.
Best Starting Point For Most Buyers
Start with the newer model if you host outside or need more punch from a single speaker. The jump to 30 watts, the USB‑C convenience, and the deeper low end make it the safer buy for open spaces. Grab the older model if you’re price‑sensitive or want one device that does stereo and quick calls. It’s the bargain route that still looks and feels like the same tough family.
